this is the tutorial for women. i'm sorry for the crappy outlining of the colors but it's just to see the lines a bit better.
curvy: start with your skeletal base, doodle a curvy women's outline, then add in detail
straight a: same as curvy women but make the base of the waist a bit smaller.
loli: same as curvy women and straight a, only difference is to make the waist smaller then the chest.
i hope it's helpful~ :3
