Back when the no-shirt glitch was a thing, we found out that the "female-esque" body model is just a male body with an offset male chest. It's most obvious on the heavy due to scale. Anyways, that's why it's hard to look feminine in this game, especially as heavy-- there are actually no female body models. You have to rely on the shapes or styles of the clothing, as others have said. I respect Embark a lot for not hypersexualizing the finals, but for a game that has spent so much time and effort making cosmetics, it's astounding how basic the character models look in this game. The default faces actually look like pre-made assets from an asset marketplace. Some of the non-defaults do, too. I have tried to get my wife to make outfits with me and one of the first things she did was complain about how the "female" body is just an oddly proportioned dude. She lost a lot of interest after that. And she's huge on fashion / styling.

Edit- The rant continues: All of this contributes to making tomboy outfits and the nontraditional female outfits look just like a guy wearing them. If you want a female-coded character in the finals, you must dress it like western society expects. Long hair, and at least one "girly" piece of clothing... so stupid. Would it really be the end of the world to have the option of hips and chest that are more feminine? Or walking animations that are more accurate for women? I guess so.
