I know there's always the concerns about budget, time, etc, but I think this is not something that should be low on the priority list in any way.
To me, it's VERY IMPORTANT that what I see on screen somewhat relates to the idea I had in mind when coming up with a character. If there's a wide disconnect, I simply end up playing someone/something else, because the look is too much in conflict with the idea. A lawful good human wizard and an evil drow wizard don't shop the same place.
I've passed on many RPGs (looking at you, BioWare) because I didn't like the possible looks on the characters.
Thankfully, regardless there is a very active community in Nexus that is dedicated to providing your characters with the coolest outfits.
