Currently it's already possible to make look of your own... just mix and match races and colors, and you can get some special results as well. To illustrate, this is my current armor:
Rocci's new armor
Just spend some time with the BM dressing room (spriteh posted the link) and you can make all sorts of looks. I have this one for hunting, and the exact same one in white for harvesting. Use your imagination.
Theres (12*8)^5 options for light armor alone. That's 8153726976 combinations... same for MA... for HA it's even more... 782757789696... I doubt those will all be used one day... even if you leave out the basic/fine colors you still get amazingly high numbers.
EDIT: Forgot to add in caster pants... so basically for LA there's even more options...
