"When anybody thinks of that era, you think of that movie," says Kevin Kinkead, co-owner of Boomerang, in Kansas City, Mo., which rents and sells 1970s-era clothing and accessories. Men were the definite peacocks of the disco era with their shiny shirts, tight polyester pants and platform shoes.

And don't forget the gold chains.

Ladies in the days of disco often wore sheer chiffon-style ankle-length dresses. "People don't realize the dresses were on the drab side," Kinkead said.

Dresses can be glammed up with shimmery sheer pantyhose, metallic shoes and glitzy jewelry. Many women attending disco parties go for their interpretation of the era instead of the reality, wearing glittery tops and bell bottoms. And some men wear reproduction shirts because they're flashier, too.

Or, again, you can look to "Saturday Night Fever" for inspiration. Because the famous dance floor cost so much, the filmmakers saved money on the rest of the club set by decorating the walls with colorful blinking Christmas lights and aluminum foil.

But don't try to re-create the film's dance floor. Instead, play the movie on your TV (set to mute because there are some sad scenes) and admire the flashing colorful squares in the background.

Hand out sports whistles on strings, aka disco whistles, as party favors. Guests can wear them around their necks and blow them to the disco beat as they dance, as they did back in the day.

Lower the disco ball and throw confetti when the clock strikes midnight. Play "Last Dance" by Donna Summer as an unsubtle cue that it's time for guests to ease on down the road.
