I made a Night elf with pink skin and I sort of regret that now. I wish there was a free character re-customization service, like when you change your hair at the barber it would let you change how your character looks. Anyway, are you able to do a race change to the same race? I know a race change lets you customize the appearance again. I could switch to human and switch back to night elf if it doesn't let you change to the same one but that would be more expensive.
