Well, with jobs we're getting job-specific gear, if I remember that concept art post on Lodestone that featured some pretty fierce looking mage clothes (among others). Also there's quite a bunch of NPCs with unique(ish) looking threads in game right now whose thread's I'd love to steal! (mostly different skins, not the actual 3D models). Hopefully all of that soon.
Perhaps the term used should be 'attractiveness' instead of 'sex appeal'?
More than fashion, I want better character customization, in as near a future as possible. We don't all got to have porcelain waxed skin, some of us would actually like diversity in form of body hair >_> As well as more hairstyles/face hair options. The Highlander Hyur have what? Like, 3 types of hairstyles to chose from? And it's not fun seeing many people with identical face tattoo patterns in only a different colour :x More scars, more birthmarks, more everything :U
And toe-long beards and hair for Lalafels so I don't feel weird when I pet them

It'll also make them look like cousin It
P.S. Whatever happened to the barber shop suggestion thread?
