The idea of customized clothing is a pretty cool one. I'd much rather have a few items that fite like they're supposed to rather than a closet full of stuff that almost fits (it'll cost about the same too). In that quest, here a few links for your perusal:
Custom Jeans
A bunch of custom clothes
Custom fleeces
Customized kicks. Wicked!
OK, this one's not clothing but it's still customized right?
