1970s disco costume

Most disco suit sets include four pieces: a jacket, a shirt, a vest, and matching pants.

Kids' retro sets often include accessories such as belts, headbands, fingerless mesh gloves, tulle overlays, and leggings—sometimes sold together as part of a multi-piece ensemble.

Common configurations are four-piece suit sets (jacket, shirt, vest, pants), single-piece shirts, and some children's outfits sold as larger multi-piece sets—occasionally up to seven pieces when accessories are included.

Disco costumes are promoted for Halloween, themed or retro parties, stage performances, group events, parades, and bar crawls.
