A young girl dressed in a Kigurumi costume of Marceline the Vampire Queen from Adventure Time. The costume is a black and white skeleton design with long, flowing hair attached to it. She has dark hair styled straight down her back, parted in the middle, and bangs that fall just above her eyebrows. Her face is painted white, except for her lips, which are bright red. She wears black sandals on her feet. In the background, there's a blurry grassy area with trees visible behind her. The image appears to be taken outdoors during the daytime.
