@OP I wouldn't call that armor sexy. The words 'trashy', 'garish', and 'tasteless' come to mind. I don't mind some delicate or even elegant armor but it's still armor and your examples are way over the top for this game. It's BG3 not 'Succubi from Mars'.
and BG3 is a game rated M for mature with nudity and full sex scene, where is the problem with having some "cleavage" on robe and armors that are magical on top of it?. why limiting it like that?
this is not a game for kid by the way its for adult.
check the full post, I linked plenty of robe and armors, and even 5e rule for sexy armors
I'm sorry but as an adult I find that armor pretty immature and more something a horny teen would prefer.
