Found this tutorial on learn-to-draw.com and tried, this is the result. I'm going to streamline the steps as much as possible:

1. Draw the head. In this example it takes 3 rows

2. Individuate nipple level, 1 head downwards. Leave a little space in the center and draw two circles for the boobs. In my example the breasts have a radius of 1 row

3. the neck is half a head long, 1,5 rows in my example, shoulders included

4. refine the neck, shoulders and bust shape

5. Go 1 head down (3 rows) and draw the navel. Then 1 more head measure down and draw the crotch

6. 1/3 head (1 row) up from the navel and 1/2 a head measure on both sides (1,5 rows). Congrats, you have the waist's thinnest point

7. Midway between the navel and crotch, 1,5 head measure (centered). Those points are the widest hip measurement

8. 1 head down and you get the knees level, 2 more heads units and you have the ankles

9. Feet are 1/2 head units tall. In total your figure should be 7,5 heads tall

10. For the arms, 4/3 head units (4 rows) and you get the elbow, 1 head measure and you are at the wrist level

11. I admit the armpit is a bit off, it should be at half head from the shoulder. Also the fingers should reach no further than 7 rows from the armpit

12. You now have the basic shape on which you can add details

13. If you need to do a profile, a tip: on normal "thickness", from front of crotch to back of ass cheeks it should be 1 head measure
