Mostly with the Romulan/Klingon outfits, I have noticed that the color palettes are messed up. For example with the Romulan/Klingon bracers 2, with the left arm you have access to the whole color palette, but with the right one you it is limited to two lines of color.
Also you can not wear any other outfits. Whenever you try to switch to another nothing happens.
