Leanna is a five-year-old girl who loves superheroes. When she wears her superhero clothes to kindergarten, though, the boys tell her that superheroes are “for boys.” She has even started to wear her jacket all day to keep from being hassled about it. (For the record, princesses aren’t “for girls,” either.)

Her seven-year-old sister Adalina has declared Wednesday, October 1, to be Wear Your Superheroes Day. Boys and girls of all ages who believe superheroes are for EVERYONE should wear their superhero stuff on Wednesday and post a picture with the hashtag #WearYourSuperheroes. Solidarity!
