To dress up for a disco party, look for shiny, stretchy materials, like spandex, Lycra or velor. Choose an open-necked button-down shirt, shiny, long-sleeved top or mini dress. Then go for an extravagant pair of bell bottoms or torches. Look for a pair of platform shoes and make them shiny to blend into your disco look. You can also have pieces with bracelets and necklaces or shiny chains. Wear your hair long and straight or give it volume with gel or hair spray. If you wear makeup, use black, brown, purple or blue eyeliner and a floating eyeshadow to complement your 70s outfit. Read more for more tips, including how to choose a disco style.
