I would wear the white canary suit plus a mask just because it’s so cool and I love Sara Lance. In reality if I was a superhero I would make up my own suit but out of these choices Sara’s suit for sure.
If I had superpowers (speed?) then Flash, just as long as it's not the season 5 suit. But if I don't, then I'll take Green Arrow, either season 2 or season 8 suit, but I wouldn't mind the 5-6(?) suit either.
