Diamond, Houseki no Kuni

A woman dressed in an elaborate costume, posing for a photograph. She has short, light blue hair styled in bangs and worn down over her face, with a few strands framing her cheeks. Her eyes are brown, accentuated by dark eyeliner and mascara. She is wearing a black romper-style dress featuring a white collar and belt, paired with white knee-high socks and black Mary Jane shoes. The outfit is completed with a black tie around her neck and a matching bow on the front of her dress. The background of the image appears to be an indoor setting, possibly a convention or event venue, given the presence of people in the distance. Overall, the woman's costume suggests that she may be attending a themed event or participating in a cosplay competition.
