Aw Friday, I am so jealous! I hope you have an amazing time. I would say go in some glam rock style gear or even Jem and the Holograms but I fear most folk would have the idea! Hope you find something.
Here, Throbbinhood, you can be arrested if you are wearing any clown gear. Had 3 reported incidents within the past few weeks and its a rural area. Feel for the real clowns who entertain at the children's ward who cant wear their working gear.
