There was definitely some dodgy outfits during the seventies, but for a fancy dress party, why wouldnt you want to throw on some sequins, flares and frilly shirts. If you are becoming a disco dancer with a Travolta outfit, or would rather become a groovy dude, then look no further. Pimps were also a big part of the 70s fashion, so go a bit wild with animal prints, big hats, big jewellery, a cane and insanely bright colours. Fancy dress has never look so groovy!
