Yes! It's a chick(en)! 
She had removed her unwanted feathers in order to get tan all over and look great. That's why her wings are like that.
Well, I guess that way it is easier to use them as "hands", but she will have to wait a bit during fall before the feathers come back (yeah, I know, in reality, it can't happen).
And as for her shirt, well, I put on it the french flag, but just because I wanted to fill it with something. But then, one of my friend said she was the girl version of "Le coq sportif", a famous sport brand in france, that litterally means "the sporting chicken" (remember that the french mascot is the chicken
).
I found what he said very funny, and so I was hesitating about changinf the title of it ^_^
