Most glitter garments use polyester or nylon. Swim shells often use a nylon/spandex blend (listed as 82% nylon, 18% spandex) to provide stretch and help the suit retain its shape.
Care varies by item: many glitter swimsuits recommend gentle handling (hand wash cold and hang/line dry) to protect glitter and elastic. Athletic or coordinated sets typically list machine-washable instructions and may allow tumble drying or recommend line dry/lay flat—follow the product’s specific care label.
Support features vary by style: some strapless pieces include built-in underwire and non-slip lining, many swimsuits are fully lined, and certain sizes offer removable padding (noted in some Big Girl sizes). Check each product’s details for exact support options.
Glitter appears in several ways: all-over glitter textures or premium metallic glitter fabric, printed glitter graphics (for example glitter-print motifs like a horn), and as sparkling accents or puff-print details on coordinated sets.
Product details note performance knits for a soft feel, nylon/spandex blends that provide four-way stretch and shape retention, quick-dry and stretch-and-snap-back fabrics, and at least one swimsuit listing UPF 50+ in its specifications.
