In the shop imagery of the Oscelda, the cuirass shows a flowing backpiece/skirt. Upon equipping I found on that I have a measly towel hanging from my butt.
Personally, i'm ok with having little differences between make and female variants. They are different body types after all. HOWEVER, changing the appearance fundamentally is a BIG nope for me, and frankly, not what I payed for.
I'm really looking forward to the male variant having the same flowing backpiece/robe/skirt
