Woman in Costume at Convention or Event

A woman dressed in a costume, likely from a science fiction or fantasy series, standing in a room with people around her. She has long, wavy hair and is wearing a brown leather jacket over a tan shirt. Her pants appear to be khaki-colored, and she is holding a gun in her right hand. The background of the image shows a group of people standing around, some of whom are looking at the woman or taking pictures. The atmosphere suggests that this may have been taken at a convention or event where cosplayers gather.
