Introduction

Triangle bikini tops create adjustable coverage and a flattering neckline for every body shape.

  • Thin adjustable straps let you customize fit and support.
  • Minimal coverage design maximizes sun exposure and tanning.
  • Lightweight fabric dries quickly after swimming or lounging.

Find your perfect triangle bikini today.

FAQs

A triangle bikini top features two triangular fabric cups connected by strings or thin straps, offering adjustable coverage and a classic beach look.

Slide the cups along the neck and back ties to position them where you want coverage, tghten or loosen the strings for comfort.

They offer light support suitable for small to medium busts. Larger busts may prefer styles with underwire or thicker straps for extra hold.

Match with string, Brazilian, or high-waist bottoms depending on the coverage and silhouette you prefer for your day at the beach.

Rinse after each use, hand wash in cold water with mild detergent, and lay flat to dry away from direct sunlight to preserve elasticity.
