In the new Wandavision trailer released today, Wanda Maximoff, aka the Scarlet Witch, is seen wearing here original outfit seen in the Marvel comic books.
In the strange new trailer for the show, Wanda and even Vision are shown wearing strange clothing from past decades. There is a small clip in the trailer of Wanda in different costumes, ending with the comic costume.
Wandavision takes place after Avengers: Infinity War and End Game, with vision last being killed for the mind stone. Wanda is also set to appear in the next Doctor Strange movie, which deals with multiverses.
Another interesting comic Easter egg in the trailer is the mention of Wanda and Vision having kids. In the comics Wanda wishes two kids into existence, panicking the Avengers and help leading up to House of M.
With this awesome, true to the comics, super hero costume being featured in the trailer, we can forsee some awesome cosplay and halloween costumes coming soon.
