The fashion issue happens with pretty much every outfit that has any non-skin tight parts to it. It also messes up outfits on the old PSO2 body type for whatever reason. Any coat, cape, skirt, etc are just bugged out like that, unless you make your body into a stick figure, which in turn makes skin-tight outfits look ugly. I also contacted support about this, but haven't heard back from it. Right now the only solution is spending SG or a Salon Pass every time you switch between these outfits.
