In some CGs that show the MC body with.... Less clothing.... I don't know how to explain exactly, but the waist looks like is too low, or too large, and that looks more like a male body anatomy. I'm really bad at biology so it would be better if you google *male and female waist*. If you could hide how they look, it would really help the body look neutral.
I'm really bad at english, sorry if you don't understand well.
