Vault-Tec Cosplayer: The woman in this photograph is dressed as Vault-Tec from Fallout, a popular video game series. She wears a blue jumpsuit with gold accents and holds what appears to be a futuristic gun in her right hand. Her left arm is not visible, but she may have some sort of device or tool attached to it. The background of the image is blurry, but it seems to be an indoor setting, possibly at a convention or event where people are gathered together. The overall atmosphere suggests that the woman is part of a cosplay group or community, and she is posing for photos with her fellow cosplayers.
