I think an 80's theme party sounds like a great idea!

big hair, legwarmers, sweater dresses (which are making a comeback), balloon skirts (also making a comeback), lace a la Madonna, ripped jeans with leggings underneath, bandanas, headbands, spandex (yes, shudder!), vests, gloves with the fingers cut out, day-glo, hyper-color, biker shorts, long belted belted t-shirts, jellies, jelly bracelets, super pointy-toed shoes, dark bras under white men's dress shirts, denim denim denim denim denim denim
...ack! when i think of some of the things we wore!
