Sailor Mercury

A woman dressed in a blue and white costume with a large bow on her chest. She has short, straight hair that is dyed blue and cut in bangs. Her eyes are brown and her eyebrows are thick and dark. She is wearing a gold headband with a gemstone in the center of her forehead. The background of the image is blurry, but it appears to be an outdoor setting with people standing around. The overall impression of the image is that it was taken at a costume party or event, possibly a convention for fans of Japanese anime and manga.
