The CW released the first photo of Ruby Rose at Batwoman on Tuesday.
Four-time Oscar winner Colleen Atwood designed the skintight red and black costume for Rose. Her look also features flowing red hair and a scarlet-tinged cape.
The Orange is the New Black alum is reportedly already on set in Vancouver for the role.
Batwoman will make her first appearance on Arrow on December 9, as the show's Greg Berlanti works to create a standalone series about the lesbian superhero.
The Vampire Diaries' Caroline Dries will be writing the script.
