The customization needs to start at character creation for sure so you're not forced to start the game in the wrong clothing.
Spellcasters especially.. they're kind of forced into a spellcaster uniform without any personality whatsoever. I want a long coat and pants, or basically anything edgier than a flat robe.
There's some kind of a tinting system in place already because NPC's in the same armor have diferent colors. Hopefully that will extend to PC's. BG1 had it in 1998. =)
