Beautikini
Beautikini sells period-proof swimwear, leak-proof underwear, and maternity-friendly swimsuits priced $28-$68, squarely in the mid-range. All sales flow through its own Shopify-powered site and Amazon storefront; no brick-and-mortar stockists are listed.
The brand’s core technology is a three-layer gusset—quick-dry outer, absorbent middle, and leak-proof TPU barrier—built directly into bikini bottoms and one-pieces, eliminating the need for tampons or pads. Styles are fashion-forward (high-cut legs, color-block sets) rather than clinical, and every suit is advertised as chlorine- and salt-safe for 100+ washes.
Customers are Gen-Z and millennial women who swim, surf, or travel during menstruation and want discreet, eco-friendly protection; many post TikTok reviews citing zero leaks on heavy days. The label also courts post-partum mothers with light bladder loss and tweens buying their first “real” swimsuit.
Beautikini competes in the functional-intimates space against DTC period-apparel labels and mainstream swim brands now adding “leak-resistant” lines. It differentiates by focusing exclusively on swim, offering mix-and-match sizes (XS-3X) with bust support up to F-cup, and backing every order with a 90-day leak-free guarantee plus free returns on worn product.
Swim freely on your heaviest days, no pad required
