What are some good ideas for a disco-themed party?

Ideas for a disco-themed party include a costume contest, a dance contest and karaoke. Guests are challenged to wear fashion trends from the era and are judged by category. Widest bell-bottomed pants, highest platform shoes and best hair are some examples. Prizes are awarded to the winners.

Hosts can hold a dance-off. Dancers are judged by categories such as funniest, best rendition and most original. The Bump, the Hustle and the Bust Stop are examples of disco dances. Videos can be shown to give lessons. Rent a karaoke machine. Guests can take turns singing. Song titles can be drawn from a hat, or guests can choose their own.
