I dont think there is anything wrong with it, it might be a bit too light i agree, but i think its supposed to simulate a transparent skintight material. As in i dont think your bare skin is actually showing if this outfit was to be made in the real world. You can see the sheen off the belly that looks like the same luster on the legs and the transparent material on the sleeves from the concept art. Furthermore, this makes sense, i think its supposed to be a "catsuit" with some flare, so it should be a skin tight full-body suit. You can see what looks almost like a zipper in the back, the only silver metallic looking line on the whole outfit. This also explains how the outfit's seams and patterns are secured where they should on the body even in motion. Revealing and a bit deceptive, which makes it sexy.
