This is actually a second attempt, very much inspired by the Scarlet Witch cosplay worn by Valerie Perez who can be seen in this picture with my ol' pal Franchesco! [link] dress as Zatanna plus my own touch that I have to add to everything.
Hmmm... Not so sure they would go for Scarlet With so soon and I'm really not sure if something along the lines this costume would work.
I did read that Marvel Studios could use the Scarlet Witch and Quicksilver if they made no mention of the X-Men franchise or Magneto and Fox could possible use them in the X-Men as long as there is no link to the Avengers. I guess it's up to whoever uses them first if either studio wishes to do so.
