According to twitter, Sega has acknowledged there is an issue with outfits and outerwear, so hopefully they fix it come next maintenance.
Side note: some members of my alliance made some tests on the skin problem without realizing the connection to the outerwear bug. Whats interesting is that apparently messing with the Gloss Skin setting seems to "fix it". When using outerwear or outfits, if you dont have gloss at the default setting it straight up messes with the whole skin tone. Usually, little to no gloss gets the white skin while full gloss turns you very tanned.
