Of course, there is always the chance that Amell is talking about another character from his own television superhero show, but most fans already have heir own theory that Ruby Rose has already gotten to do a Batwoman costume fitting test.

Amell certainly knows what he’s doing, and with the veritable fire of excitement surrounding the casting of Rose as Batwoman, it’s a safe bet that this is exactly who he is talking about. After all, the announcement that Batwoman was coming to The CW had meen made a good while ago, meaning that the costume designers had some time to start working on the character’s suit in advance. It could be that when Rose was announced as the actress that would bring the character to life, the costume was already ready for a fitting.
