Yenra Wanda Maximoff - Scarlet Witch from Marvel's Avengers: Age of Ultron Scarlet Witch Cosplay: A woman dressed in a Scarlet Witch costume from Marvel's Avengers: Age of Ultron. She has long brown hair and is wearing a maroon jacket, black dress, knee-high socks with holes in them, and black boots. Her hands are positioned as if she is casting a spell or using her powers. The background appears to be an outdoor setting with a concrete wall on the left side and what looks like a gray or white building behind her. The overall atmosphere suggests that this is a photograph taken at a comic-con event or similar gathering, where fans of the Marvel Cinematic Universe have come together to celebrate their favorite characters.
