It's an interesting point. Thieves would be in leather, and wizards using, say, bracers, cloak, and ring (I'm showing my age here) wouldn't necessarily be completely covered up. Of course, they're used to being in back and avoiding missile fire, so dressing to attract attention might not be the smartest thing. But we could easily see an arrogant magic-user with a high CON showing off their physique, and some of the newer spellcasting classes like sorcerer or warlock that are charisma-based might make it part of their shtick--seductive enchantresses are a thing in mythology. Indeed, it wouldn't even have to be gendered the usual way--if it's magically enhanced charisma, it's not impossible to imagine a warlock distracting people (even if they don't usually swing that way) with his supernatural studliness.
And, of course, Bards. Nothing but DM Fiat stopping them from making a form of Exotic Dance their performing art of choice.
