I would love to see this as i been waiting and wanting these unlocks to happen one of these patches...they said that they will add them in in a future patch but since march nothing been said or show since which i dono't know if they will just pop up in a big surprise way or what is going on. -_-; i would give so much for these glamour pieces and just thinking of all of the ways of outfits and stuff to go with them just would be so much fun to see and do.
a couple of ideas they could do this:

have a special npc that sales these in a town and just put as their names: Hempen: hyur (of all of the races)
cash shop
market board
grand company seals

just thinking off the top of my head.
