While some people may find the classic aerobic costume overplayed, we love it for its recognizably-’80s qualities and über-comfortable nature. Make this costume unique by building a solid base and layering on intentional details. Don’t feel like walking around all night in a glorified swimsuit? Slip a short-sleeve crop top over your leotard or add a pair of dolphin shorts for a little extra coverage.

An ’80s prom queen look starts with a great dress. Look for one made from a satin-like fabric featuring the biggest sleeves, ruffles, or pleats you can find. Off-the-shoulder styles were super popular during the ’80s, along with bows, sash-tied waistlines, and floor-length hems.

If you’re into keeping it casual, there’s no better outfit for an ’80s party than simply wearing a vintage sweater from the decade. ’80s sweaters are famous for their loud colors, bold patterns, and oversized cuts. Take your pick from our large selection of vintage ’80s sweaters or dig one up at your local thrift store. The bottoms you choose are flexible: you can go the classic route and stick to leggings, or go in the direction of acid-washed jeans, a pair of slacks, or a full skirt like the one shown above.
