Triangle Bikinis

All Bikinis Bandeau Balconette Bralette Underwire High-Waisted Cheeky Plunge One-Pieces One-Shoulder

The triangle bikini is the original — adjustable, minimal and endlessly versatile. Our edit covers sliding string triangles, fixed triangles, embellished and crochet styles from the world's best swim labels.

Triangle tops suit smaller to medium busts and let you tune coverage by sliding the cups. Pair one with cheeky bottoms for a classic look or high-waisted bottoms for a retro feel. Need more support? Try balconette or underwire bikinis, or browse all designer bikinis.
