I would love to be able to dye the outfits.

each race does have its own lore...(some of it you can read in-game when you make a race.)
there's even some set of subquests involving the duskwight elzen the underground ruins that they used to live in to avoid the elementals wrath ages ago in the black shroud.

most races don't originate in Eorzea, however which is probably why there isint a whole lot of talk about racial things.

Even so i wouldn't have much of a problem allowing others to wear it.

knowing SE it would be crafted vanity though~ (which i wouldn't mind either. but i know some people would lol)
