Shiro (manga costume)
One of the lead characters from "Deadman's Wonderland" (anime and manga). I asked why her costume has so much red in it (the character is normally all white with some red swirls on her costume). She said that this was from one of the manga covers and not her normal costume. Fair enough. Still looks good on her.
Tech stuff: had to use PS to move the front of her wig down two inches as it had slid back and was showing the cosplayer's real hair; and used Topaz Adjust to add a bit (~11%) of extra texture to the whole image.
