I don’t have to imagine Elizabeth Olsen wearing the revealing Scarlet Witch costumes from the comic books because she actually did so in the “Halloween” episode of WandaVision.
One person who would care having Wanda Maximoff wear revealing costumes more often is Elizabeth Olsen herself. She said in an interview that she found the “cleavage corsette” costume she wore in Avengers: Infinity War was too revealing:
“I like corsets, but I’d like it to be higher. Everyone has these things that cover them — Tessa Thompson does, Scarlett does. I would like to cover up a bit. It’s funny because sometimes I look around and I’m just like — wow, I’m the only one who has cleavage, and that’s a constant joke because they haven’t really evolved my superhero costume that much.”
Many other people would find it sexist to have her wearing revealing clothing when fighting whereas the men dress more sensibly.
Question answered: Can you imagine Elizabeth Olsen wearing the revealing costumes from the comic books? Will anyone care if the costumes are too revealing?
