Superman costume

You take the Superman suit with cape. You've never done Superman, and you think you'll look good in tights. When you try it on, a slight breeze blows through your hair.

You make a fake leap with your arm outstretched, just clowning around. You fly up through the ceiling of the store, crashing through the plaster and wood. It didn't hurt.

Flying feels amazing. Near the costume shop you notice a blue-and-red-clad form floating in the air. As you get closer you see that it's Supergirl.
