Triangle Bikinis

What Is a Triangle Bikini?

A triangle bikini top is two triangle-shaped cups connected by ties — one tie around the neck, one across the back. The shape is the definition: the cups are cut as triangles, and strings do the fitting.

Triangle is a top construction. The bottoms vary — string, Brazilian, thong and cheeky all appear with triangle tops, and the collection includes full sets.

Triangle names the cup; ties do the fitting.

Triangle Construction Types

Triangle tops differ in how the cups are built and adjusted:

• Tie-string triangle — classic neck and back ties, fully adjustable.
• Sliding triangle — cups slide on the band to change coverage and position.
• Padded or underwire triangle — cups with built-in structure.
• Solid vs. micro triangle — cup size runs from barely-there to full triangles.

Ties are the adjusters: retying the neck or back changes how the cups sit, and sliding styles let you move the cups themselves. The same top fits differently tied loose or snug.

Cup shape sets the look; the ties set the fit.

The Styles in This Collection

Triangle tops show up across these silhouettes:

• Triangle string thong sets
• Sheer and micro triangle sets
• Solid triangle Brazilian bikinis
• Sliding triangle styles with rhinestone or backless details
• Ribbed, vinyl and wrinkled-fabric triangles
• Neon-trim and animal-print triangles

Prices run from about $22 to $40, and sizes from XS to XL with a few one-size pieces.

Pick the cup first, then the tie style.

Wearing and Fit

Ties are the fit mechanism: the neck tie sets how high the cups sit, the back tie sets how snug the band holds. Cups should sit flat with no gaping at the top edge, and ties should hold without digging in.

Sliding triangles adjust coverage by moving the cups together or apart on the band. Ties can loosen in the water — retie after swimming. If you prefer more structure, look for padded or underwire triangles; unlined styles are the lightest.

Ties adjust, cups sit flat, retie after a swim.

How to Choose

Work through four decisions:

• Cup: micro, classic or padded
• Adjustment: tie-string or sliding
• Coverage: how the cups and bottoms balance
• Bottom: string, Brazilian, thong or cheeky

Sizes run XS to XL with some one-size pieces — check each listing’s chart.
