I have… well. Mixed feelings about this whole issue tbh.
Most armor, like the one in OP, would look about the same regardless. The only difference really would be size & height maybe. And most armor in the game by far is large enough to hide most body proportions anyway. Remember we’re not talking about regular people from today, the women & men in Darktide are buff & built for combat.
But there are some costumes where I find this an issue, like the vet’s prison garb tanktop thing. Someone posted pictures showing that it’s literally the same model for both a while back, one just a bit smaller than the other. Not a huge issue on its own, but it is when we can literally see the underwear model sometimes so it’s so obvious that the tanktop doesn’t go on the same body but is really just a full torso replacement. Combine this with our ridiculously lackluster face & hair style options and it’s definitely annoying. 
But this is why the mixed feelings.
On one hand, I’d much rather take what we have here than yet another over-sexualization garbage.
On the other, why the heck is the male model the default yet again? If we’re talking equality, making us look the same as men seriously isn’t doing it for me. And why the heck are men the default and #1 choice in every single UI, database, gender/sex selection system etc. anyway? As if that wasn’t a fantastic example of our cultural & unconscious bias. I think it would be a far better statement if they did the opposite and went with women as the default for once.
Anyway the issue here comes down to one thing: choice. You’re free to look at literally any game popular with women with customization options. You’ll see most of us actually want to look good, but on OUR terms, in a way WE want & like. Men making women over-sexualized is bs, obviously. Men making women look like men? It might be better, but it’s still men making the choice for us, for everyone of any gender. It’s still the same problem! The only difference is in degree.
I know it’s not this simple with game design, artistic style etc. and all. Few games actually have a robust character creation with tons of customization options for anyone. And all in all, Fatshark has done things far better with Darktide than many others. But still.
But what really annoys me is how this whole subject no matter the game is so permeated with incels that I feel dirty even talking about it, nevermind seemingly taking their side (which I’m not). So after everything is said and done, I’d much rather take what we have here than the other thing. … Even if I seriously want more and prettier faces & just a whole lot more hairstyles than we have.
