Much like the pink controversy, I think all characters should have access to all of the clothing options, even if the defaults remain. However, mapping those items to the other character models (every item in-game and all dyed variants onto every possible character) would take even longer than making more colours accessible. I doubt this will ever be implemented, but I certainly want it to be.
I agree. I was disappointed to see that the "Santa" hat on female characters actually look like some Pilgrimage hat. I know it's supposed to be Mrs. Claus' hat, but I prefer the traditional Santa hat that should be gender neutral. (The female option could come without the beard)
