What swimwear is allowed at Masters meets, and can it be modified?

Question

Accepted Answer

World Aquatics swimwear rules apply to Masters Swimming Australia competitions.

Swimwear includes goggles and caps, and up to two caps may be worn.
In pool competition you wear only one swimsuit, in one or two pieces. Items such as arm bands or leg bands are not regarded as part of a swimsuit.
For Masters competitions, a suit that complies in shape and material (permeable open mesh textile) can be used even if the model is not on the World Aquatics approved list.
You must not wear or use any device or swimwear that may aid speed, buoyancy or endurance (for example webbed gloves, flippers, fins or adhesive substances).
Tape on one or two fingers or toes is allowed if needed to treat or protect an injury.

Modified or alternative swimsuits: swimsuits may be modified, or alternatives worn, for individual needs including modesty, religious or cultural purposes, gender identity or physical disability, provided the Referee approves them before your first event at that competition. Such swimwear still qualifies for a National record or National Top Ten. For World Aquatics Masters World Records and World Masters Top Ten, a World Aquatics approved swimsuit is required.
