“Alright; Mom said we all have to find a dress today and she wants us all in black and white for our family pictures” 17 year old Leah Wilson told her two younger sisters as they all got into the car.

12 year old Kennedy got in the front seat and 7 year old Riley climbed into the backseat.

“We’re heading to the mall and I don’t want to spend all day there” Leah told her sisters.
“Whatever” Kennedy said shrugging her shoulders.

“We’ll only be there all day because of you anyway Leah” Riley said buckling up. “You’re the one who can never make up her mind. You’ll be all like ‘Oh I don’t like this one or this one is too long or this one makes me look fat or…’”

“That’s enough Riley” Leah said starting up the car. “Mom put me in charge of making sure all of us look good for these pictures so you need to listen to me today”

“Yeah right, like I’m supposed to listen to somebody who dresses like you” Riley said.

“Wow…got a little bit of an attitude problem in the backseat” Leah said. Maybe I should take my fashion tips from you…do I wear my night time pull up or my daytime one with skinny jeans”

“On a butt your size Leah, everything looks like a full diaper” Riley replied.

Leah just shook her head as she started down the street “You better knock off the attitude real quick missy; I’m not putting up with your mouth the whole day. I will tell Mom about what a brat you’re being”

“Kennedy will pick out my dress for me” Riley said.

“Keep me out of this” Kennedy said.

“You can act like a brat all you want and even if I do tell on you, I’m sure Mom won’t do anything to you anyway…you’re such a little brat. Must be nice to be the baby and get away with everything” Leah said.

“What are you talking about; you’re the one who gets away with everything. You can boss me around and Mom never questions you, it’s always ‘when Leah’s in charge, she’s in charge’” Riley said, dropping her voice lower to try and sound like her Mom.

“That’s how it should be. I’m the oldest and Mom put me in charge for a reason” Leah replied angrily.

“Well I’d like to be the one in charge for once” Riley said.

“You think it’s so easy being in charge and being the oldest” Leah replied.

“Well you obviously think it’s easy being the youngest, but the last time I checked; you’ve never been the youngest. You’ve never been bossed around your whole life by a bossy older sister”

“I wish you could see what it’s like to have to be the responsible one. You need to be in charge for once and try to put up with a little bratty know it all questioning everything you do” Leah said. “You know what…you’re right Riley; I never have been the youngest and right now I wish I was the youngest”

“Well I’ve never gotten to be the oldest and I obviously never will. You’ll always be older than me Leah but I wish that wasn’t true. I wish I was the oldest. I’d love to see what it’s like to be the one in charge and be the one to boss somebody else around instead of always being the one bossed around by you”

They pulled into the mall parking lot still fighting as Leah parked the car. “Let’s go” Leah said.

They walked into the department store and began to browse through the clothes. Kennedy picked out three black dresses right away and then had to follow around her sisters as they took forever.

Everything Leah picked out for Riley; Riley hated. And everything Riley picked out for herself; Leah hated.

Leah found a dress for herself and made Riley take three of her choices back to the changing rooms.

As they passed under the sign that said ‘Changing Rooms’ Riley said. “I wish it would change me into the older sister and Leah into the youngest”

Leah shook her head hearing her sister mumble behind her “Yeah okay…me too. Then I could make your life a living hell instead of you doing it for me”

Kennedy sighed as she followed behind just happy to finally make it to the changing rooms “Maybe it would teach them both a lesson and get them to shut up” she said to herself.

“Try the one on top first Riley…I think it will look cute on you and if we get you a pair of white tights and some black Mary Janes, Mom will like it” Leah said as she put Riley in the first changing room and she stepped into the one next to it while Kennedy went across the way.

“Whatever…shrimp” Riley mumbled enjoying her daydream about being the oldest. She could see herself in her mind being prettier and taller than Leah ever was and trying on a short and tight dress like the one Leah had picked up. She would twirl and spin and wear some really high heels.

Then she would barge in on little Leah in her dressing room, trying to put on a frilly and poufy dress and just tower over her. She could just see the look of fear that Leah would have in her eyes looking up at her big sister Riley for a change.

“Come on over there” Leah called out.” You need to get changed”

“No, you’re the one that needs to get changed…into a 7 year old” Riley laughed.

Riley took of her jeans and pink t-shirt and stepped into the dress. The tulle scratched her legs as she put on the dress but she got it on and zipped up before she opened the door and walked out to the mirror.

She fluffed out her long blonde hair so it sat on her shoulders as she frowned at the reflection. “I don’t like it” she said.

Leah came out of her dressing room then and walked barefoot over to where her little sister stood pouting before the mirror. She was wearing the black dress she had picked out. It came to her mid-thigh and was held up by spaghetti straps that showed off some cleavage.

“Mom won’t like your dress at all” Riley said crossing her arms.

“I’m planning on getting a white sweater to wear over it: She’ll be fine with it” Leah said as she turned to the side then put her back toward the mirror. She pulled her brown hair up to see her neck before letting it fall back down again.

“I like that dress on you” Leah told Riley.

“If you like it so much why don’t you wear it” Riley replied.

“Just go try on the next one” Leah said exasperated.  She shivered as she walked back into her room.

Riley quickly pulled the zipper down and let the dress fall to the floor. She picked up the next one and got it off its hanger.

She stepped into the dress and the first thing she noticed was that it felt tight on her. She pulled up to her waist though and was at least happy that it was softer than the first dress.

Riley put her arms into the sleeves and yelled over the top “I can’t even get my arms in the sleeves of this one…it’s way too small”

“It must be mislabeled then” Leah said in return. She turned to the mirror inside her room and said to herself “Just like this must be…I didn’t think it was this big, but this is huge on me…doesn’t fit at all”

There was now a gap in her shoulder straps as they bowed outward. Leah could put two fingers in the front of her dress and pull it out; it came nowhere near hugging her chest and as she stared in the mirror at her hips and waist she said “It doesn’t show off anything…it’s like I don’t even have any hips when I wear this dress.

Leah tugged at the bottom of the dress and it came down several inches on her thighs to just an inch above her knees “What the heck…” she mumbled.

Riley had managed to work the black dress on despite how tight it was feeling. She had to suck in a deep breath to get it zipped but she did it.

She wanted to giggle at the sight of sleeves ending several inches above her wrists but she had to keep sucking it in as the dress now felt even tighter on her than before.

Riley felt an itch begin on the top of her left foot, so she brought the heel of her right foot over and rubbed it across hoping it would take care of the situation. When it didn’t, she started to bend down to scratch her foot but what she saw and felt stopped her dead in her tracks.

When Riley bent over, the zipper popped and gave way on her back. It ran all the way down exposing her back. “Oops” she said but as she looked at her feet, she realized that something was different about them.

She looked puzzled but then she saw them wiggle on their own and begin to grow. She let out a quick “AH” that even sounded different; it sounded lower than usual. Riley could feel her feet moving and spreading out wider and longer on the short rough carpeting inside her changing room.

More than that, she felt herself lifting up; getting taller as her legs grew longer and started to develop curves. Her tiny dress strained at her waist as she began to develop hips and her ass began to grow out and fill in.

Riley struggled to get her arms out of the sleeves of the dress but she was a bit too slow. Her biceps flexed and expanded and ripped the light fabric of the sleeves to shreds as her hands and fingers began to grow longer and larger.

In the next stall over, Leah was feeling concerned at how loose her dress was “How did I even pick this out and try it on in the first place” she thought as she felt the strap droop off her left shoulder and hit her upper arm. “I...wait a second…something’s not right…I’m not this small…I can’t be that small”

Leah looked in the mirror. Her eyes widened and her jaw dropped at what she saw: Leah was little and getting smaller by the second. Every fiber of her being wanted desperately to scream out in terror but she was instead frozen in place.

The black dress that had fit her when she first put it on now hung on her like a sail. She looked in the mirror and then down at herself and was shocked by what she was becoming.

Leah slapped at the front of the dress and her chest and all she hit were two small swollen lumps, no breasts were there. Her hands grasped at her non-existent ass and her now straight and narrow hips. Her legs stuck out like skinny pencils from the bottom of the dress.

Her hands and feet were even smaller she noticed but it was her face that disturbed her the most. Her face looked like it belonged to a little kid. Her cheeks were puffy and her mouth shrunken with thin lips. Her eyes were large but her nose was tiny as were her ears. Freckles began to dot her face as even her hair began to change style and texture.

Her hair suddenly swept forward into a set of stringy bangs like what she wore when she was…it hit her then “I look like I’m seven again!”

Riley quickly crossed her arms in front of her chest as breasts budded and grew large on her chest. Her shoulders and back grew and she finally looked up into the mirror and saw her face.

“Oh My Gosh…” she began as she took in what her face now looked like. Full deep blue eyes sat out over high cheekbones and a thin aquiline nose. Her mouth was full and her chin pointed and defined and it was all framed by silky blonde hair that waved as it came down to her shoulders. “…I’m gorgeous…and I’M OLDER” She yelled out triumphantly.

Leah swallowed hard when she heard the deep voice call out from the next stall over. Her heart began to race “Oh No…it came true! Riley’s big and I’m little! I can’t let her see me like this” Leah thought as she backed herself into the corner.

Leah let out a high pitched yelp when she saw large feet move closer to the dividing wall and the person on the other side begin to crouch down.

“Hey little sister!” Riley called out as she ducked down, got onto her hands and knees and peeked under the bottom of the divider. “HAHA…You look so cute like that. I thought I’d find you looking like that. Looks like our wishes came true: I’m the big sister now and you are the little sister now. Isn’t this awesome!?”

“What do you mean awesome…” Leah whined.

Riley stood back up “Hey why don’t you do your big sister a favor and toss that dress over the top to me…I need something to wear to cover myself up now”

Leah was shaking but she picked up the huge black dress and flung it under the bottom.

“Thanks and here” Riley balled up the first dress she had tried on and scooted it underneath back to Leah. “Since you liked it so much…I want to see you wear it. Oh and give me your underwear while we’re at it…not like you need it anymore…you look pretty flat over there”

Leah did take off her underwear and sent it through to Riley. “What happened to me?” she thought in a panic. “This isn’t real…this can’t be real…” she was chanting as she heard the door next to her open and Riley stomped out.

“Your bra is really tight sis…I had no idea you used to be that small but this dress fits me awesome anyway” Riley said turning back and forth taking her mature body in the mirror “This…is…awesome”

Riley walked back and knocked on Leah’s door “Open up sis…I want to see how cute you look in that dress”

“No” Leah said shocked at how different her voice sounded.

“Listen you little brat, you’d better listen to me or I will leave you here. If I’m 17 now, then obviously I was the one that drove us here and I can drive off without you so get out here now”

Leah quickly put on the girls size 8 dress and undid the lock.

At the click, Riley pushed her way in and saw the look of fear in Leah’s eyes “Precious” was all she said.

Kennedy had listened to all of this in stunned silence in her own dressing room but now she finally opened the door and nearly fainted at what she saw.

“Oh hey Kennedy, I almost forgot about you over there” Riley said. “Surprise” she said as she bent her knees and threw her hands and arms straight up “How do you like your new big sister”

“I can’t believe what I’m seeing” Kennedy mumbled.

“And don’t forget to say Hi to your new little sister” Riley said waving her hands toward the small Leah like she was a prize on The Price is Right.

“Leah…Ohmygod…you’re so…so…little!” Kennedy said.

“I know…I…I guess I shrunk” she said with a shrug.

“Did you find one you liked Kennedy?” Riley asked.

“Um…yeah…I guess so…but what are we going to do about you two?” she said.

“Nothing” Riley answered quickly. “This is how it is now and I don’t see a problem with it, do you?”

“Um…what’s Mom going to say?” Kennedy asked.

“We’re going to find out aren’t we” she said as she pushed past Leah and went into the second dressing room. “We’re getting these three dresses so you need to get changed back into some clothes that fit you Leah” she said pointing to the room she had come out of and closing the door of Leah’s room after she went in herself.

Once inside, Riley took off the tight black dress and got dressed in her sister’s white tank top and denim shorts before she slipped on her flip flops.

Riley grabbed the purse that had been Leah’s and opened it up. She found the wallet with the money their Mom had given them but more interesting was when she found the driver’s license. It had her picture and name on it instead of Leah’s.

Leah staggered into the changing room and blindly got dressed in Riley’s jeans, pink t-shirt and white sneakers. She couldn’t even process what was going on before her big sister was knocking again saying “We need to get to the shoe department still…let’s go.

Once there, Kennedy again found her own pair while just staring at how her sisters, not quite believing that they had swapped places. Riley picked out a pair of size 4 Mary Janes for Leah and started trying on pumps in ladies 9 for herself. Leah was mortified when they were a size too big.

As Riley posed and checked out a pair of 3 inch heels, the cell phone in the purse went off and all three girls momentarily panicked.

Riley tossed it to Kennedy “You’re the only one who sounds the same: Answer it”

“Hello” Kennedy said.

“Oh hey Kennedy” their Mom said “How’s it going at the mall?”

“Um…I don’t know”

“What do you mean you don’t know; did you all find dresses?”

“Yes” Kennedy answered. “We’re shopping for shoes right now”

“Tell Riley nothing too high” Mom said.

“Um…what?” Kennedy replied realizing what she had said.

“And tell Leah to not be a brat and to not give her sister a hard time or she’ll be in Time Out when I get home”

Kennedy’s eyes widened and she felt sick to her stomach.  “Yeah” she said flatly “I’ll tell them. Gotta go…I think they’re wrapping up”

Kennedy hit the end button and stared at her sisters.

“What did she say?” Riley asked as Leah looked on hopefully.

“She said to tell Riley nothing too high in a heel and Leah to not be a brat and if she gives her big sister a hard time, she’s going to be in trouble later” Kennedy said.

Riley laughed long and hard as Leah stood shocked and said “What?!” with her hands planted on her hips.

“Oh this is too perfect” Riley realized. “To Mom this is how it’s always been; only the three of us know anything different” she laughed.

“But…but…” Leah began to weakly protest.

“So it was a size three in the shoes and a size small in the tights right pipsqueak” Riley said towering over Leah.

All Leah could do was nod “Yes Riley” she said but in her mind, she was already beginning to plot how to make her part of the deal come true.

“I may be small, but now I’m the baby of the family and I don’t think Mom will enjoy hearing about how my big sister tried to leave me by myself in the changing room…if she wants to be the big sister, I’ll make sure she has to deal with a bratty little sister”

As they walked up to the registers, Leah saw her first chance “Hey Riley…I have to go to the bathroom”

“Are you kidding me? They’re on the other side of the store” Riley complained.

“But I hafta go” Leah said playing up her age.

“Fine” Riley said in a huff and they headed to the other side.

Leah went in and stood around; she didn’t actually have to go but thought she could waste some time inside. She played with the water and jumped up repeatedly to see herself in the mirror; she still couldn’t get over seeing her younger face again.

“Are you finished in there yet” Riley yelled through the door.

Leah giggled “Just a minute…” She waited two more minutes before coming out.

“Jeez did you fall in?” Riley asked.

“I had to go…maybe my bladder is just catching up to my body getting smaller” Leah said.
She wandered and walked as slowly as she could until the got to the registers. Then she said “I don’t like my dress…I want to try on something else”

“What…you little…” Riley turned to her “Are you kidding me?”

“No…I think I liked the second dress better but I want to try it on again” Leah said calmly.

“No…we already picked out these dresses. You said you liked it so you’re getting it” Riley said.

“But that’s not fair! I changed my mind…you’re not my Mom…you can’t tell me what to do” she yelled at her sister.

“You’re going to be in such trouble when we get home” Riley said.

“I don’t care…I don’t want to look like a dork in the pictures” Leah protested drawing the attention of several of the employees.

Riley looked around and said through gritted teeth “Fine”

After they picked out four dresses for her to try on again, Leah announced “I have to go to the bathroom again…I can’t help it” and she took off for them quickly getting out of Riley’s sight.

“Leah get back here where I can see you” She looked around. “Kennedy! Go find your sister”

Kennedy sighed but headed off toward the bathrooms to look for Leah. She found her standing in the returns section.

“Oh…it’s just you” Leah said.

“How long are you going to do this?” Kennedy asked.

“Until she realizes that she hates being the big sister and changes us back” Leah admitted. “So sit tight big sister…we’re going to be here for a while”
