You walk out in the pink one, listen to the police, gasp demurely, then say “excuse me for a moment” and come back out in the black one. Sounds reasonable and completely unsuspicious.
I am Silver Tongue, I am an artist. I have many characters and you can check out my art in the art tag. I occasionally practice witchcraft though I don't do anything too complicated. I am girl 2 and don't know what else to put here.
