TLDR: Big hero female default
There are 3 default bodies, Basic hero male, basic hero female, and big hero male. I'm not suggesting large woman for the sake of being PC, but there are characters in pop culture who fit this body type, but aren't easily makeable just by maxing the default basic hero female bars. Opera viking women, comedic spy heroines, and serious one for some versions of Amanda Waller, really, are ones that I can think of.
My wife wanted to make a character based on the Venus of Willendorf but the character can't be made with the current body types. I understand that the creators probably didn't want to make characters that could be either taken as a mockery of heavy people or make boobs a focus of character design, but more options is more options. And if you make a large chest more saggy, it's less likely to be viewed as porny, although boobs are boobs. Just a suggestion that I know will be hard to make, but adding a new body type will also allow more future content.
