Some of the pictures OP is posting belong to one of those Asian MMOs where everyone is half naked and carries giant weapons.

But I wouldn't mind skimpy "armor".
Maybe some light armor with the belly exposed.
Or a fancy robe for clothies... they dont that much armor.

It just has to be done in good taste. Functional but "sexy".
Let players decide how they want to do this.

And make sure an armor that covers everything for men but makes female characters half naked doesnt happen.

Maybe someone wants to see skimpy Astarion. Well let them.
