Supergirl is officially making her DCEU debut in The Flash, appearing alongside Ezra Miller's Barry Allen, and now we have an idea of what her big screen suit will look like. Director Andy Muschietti has been posting photos of the various hero suits from the film on his Instagram throughout production, showing off the threads for Miller's Flash and Michael Keaton's Batman. On Friday, Muschietti offered up the first look at Supergirl's new outfit.
