We've featured Irina Ushenina aka Rei-Doll's cosplay on GeekTyrant a few times, most notably in the Catwoman Best of Cosplay Collection. Despite five films with the "not nude" blue design, when I think of the character Mystique I always envision the comic design with the white dress, long white gloves, and long white boots.
Ushenina brilliantly uses a skin tight under-suit to side step the issue of blue body paint ruining a white costume. With a perfectly matched face makeup color the whole thing feel seamless. Great cosplay photos like these are no accident and in this case took a whole team to pull off, namely, photographer Kifir, Ryoko, PredatoR, Paula, Daniel and Mario.
