alicostume 

The most slutty, whorebag, lingerie stripper outfits that you could possibly imagine. Girls use Halloween as an excuse to wear these costumes, when they really wish they could walk around like this all the time to solicit attention from the opposite sex (or anything that moves).

No, that's not an alicostume. She was wearing that to Algebra at nine o'clock this morning!
