Magenta – maid with wild red hair… black button down dress with a white apron. black stockings and stiletto boots.

Columbia – easiest is when she’s wearing her blue striped pajamas and Mickey Mouse ears.

Janet – white bra, white panties, white half-slip and white mary jane shoes (think very 70s). You could also go with the white labcoat over everything.

Floorshow – black corset/teddy, black garter belt, panties, fishnets thigh highs and heels. They also have red ribbon on their garter belt staps. One arm has a black fishnet glove, the other a red sequin glove. Just drag around a feather boa with ya

But honestly, I think anything in “the spirit” would be fine!

Be Janet. Wear a white bra and a slip. Whoever your date is can wear underwear and walk around saying “Damnit Janet!”

Panty hose, heavy face makeup, rose tinted glasses, and a transylvanian ID.

White bra and white panties or just something gothic and skimpy
