What to Wear for Water Aerobics: A Complete Guide

A secure, chlorine-resistant swimsuit or supportive aquatic outfit leads the list, with water shoes for traction and a swim cap to protect hair from pool chemicals.

Water aerobics puts fabric through repeated rebounding, arm swings, and deck walks on wet tile. The wrong suit shifts or sags; the wrong footwear turns a slippery deck into a hazard. What you pack depends on class depth, whether the workout includes submersion, and whether you’re outdoors.

Start With A Suit That Stays Put

The core requirement is clothing that stays secure through repeated movement, so a one-piece suit, jammers, swim trunks, swim briefs, or a well-fitted bikini all work — fit matters more than style. The Aquatic Exercise Association’s Standards and Guidelines notes aquatic exercise clothing can offer more support, coverage, and comfort than a conventional swimsuit, largely because many programs build in rebounding movements.

Avoid loose garments that shift or create drag, and avoid cotton, which soaks up water and turns heavy fast. Performance swimwear labeled chlorine-resistant will outlast a fashion suit by a wide margin.

For specific picks, this roundup of bathing suits tested for water aerobics takes the trial-and-error out of sizing and chlorine wear.

Water Shoes: When They Help And When They Don’t

Most shallow-water classes run better with dedicated water shoes, especially impact or traveling sessions. The Aquatic Exercise Association reports aquatic shoes can improve footing, boost traction, protect the feet, ease impact stress on weight-bearing joints, and support safer movement. Pregnant participants, people with diabetes or musculoskeletal disorders, and those carrying extra weight that loads the joints benefit most. The association also notes shoes help on wet decks, in changing areas, and entering or exiting the pool.

Street shoes don’t belong in the pool area — they track in contamination and raise slipping risks. In traditional, non-impact deep-water sessions, shoes can be unnecessary or counterproductive if they restrict ankle plantar flexion.

Goggles, Caps, And Flotation Gear

Goggles become necessary once your head goes underwater, keeping water and chlorine from your eyes; tinted or mirrored lenses help with glare and sun outdoors. Ear plugs are optional, worth adding to limit water entering your ears.

Flotation is the piece people most often get wrong. You don’t need to be a swimmer for a typical shallow-water cardio class, but non-swimmers need adequate flotation — in deep water, a belt or vest designed for aquatic exercise is standard. The association lists flotation belts, vests, and upper-arm cuffs as appropriate deep-water equipment. Land-based weights are not a substitute for aquatic gear.

Water depth tracks experience: beginner and intermediate classes usually run from waist to chest depth; experienced participants move deeper.

Final Walk-Through Before Your First Class

1. Confirm the class format — shallow or deep, impact-focused or gentle, and whether any exercise puts your head underwater.
2. Choose clothing with enough support and coverage for repeated movement, and skip cotton.
3. Pack water shoes for shallow and impact classes; leave them home for traditional deep-water sessions.
4. Add the accessories the format demands: cap and goggles for submersion, hat, sunglasses, and water-resistant sunscreen outdoors, vest or wetsuit for cool conditions.
