I tend to not go into clothing in a character sheet purely for this reason XD If required I'll describe a general style of dress, but usually I tend to use their "profile image" (or whatever you want to call it lol) to give an idea of that and then if necessary IC give a brief like one sentence or so description of clothing where it seems necessary/appropriate :P 

I always see a character sheet as kinda interchangable anyway...the character is going to develop and change throughout the course of the RP they're in (presumably, or else they wouldn't be a particularly 'good'(I use the term VERY loosely here, don't jump on me o.o) or believable character), and their CS or profile should be a general outline or a summary of that, meaning it can and will change as the RP or character develops more. ouo
