Power Girl's

Power Girl answers her door, fully costumed, having just finished her duty. "What the hell happened to you!?" She asks, upon seeing the half naked Supergirl in the corridor.

"My clothes are disappearing, let me in!" She shouts. Power Girl steps aside and Supergirl runs in. You and Zatanna sneak in after her. "You have to let me borrow a top, I start duty soon!"

"Okay, but I just came here to get changed, before and after duty, all I have is the top I came in, or this." She gestures to the costume she's currently wearing.
