I think there should be multiple styles of armour for each type. Some can be "sexy" and some can be normal for both sexes. Also dyes, we have a framework for a crafting system and can collect herbs already. Each type of armour could have racial styles and also class styles. Something like Drow Cleric style for females I would expect to be "sexy" but some others I would expect to be practical. Ideally both sexes could wear whichever version they wished but that may be hard to add since the bodies are obviously shaped differently.
Personal preference, I prefer practical armour but I am not against the inclusion of more revealing stuff as long as there are plenty of options for everyone. Of the armours you showed, the Hide+1 looks the best, of course I would like to darken it a lot more.
Oh, and please no ridiculous pauldrons unless they can be added separately for those that like them. I like spiky stuff and skulls and all that, but stabbing myself with my own armour is just not my thing.
A good idea, but I don't think they will implement it because they will have to pay for additional clothing models/concepts(??). In fact, EPIC and good-looking armor doesn't have to be exposed. You can be sexy without exposed body parts. The problem is that now there is simply no such armor in the game. Right now the most terrible clothes for magicians, my opinion. That awful robe that only changes color.
