Black Triangle Bikini

Why the black triangle holds

Why the black triangle holds

The triangle is the simplest top cut in swim — two panels, a tie, nothing to construct around. Black is the base color that pairs with everything in the palette. Put the two together and you get the default set: the cut does the minimum, the color does the rest.

The pool runs 108 styles, about $17 to $59 — the solid black triangles plus the black base builds that carry the print, the push up, the high neck cross back and the tie dye reads across the family.

How the black triangle pool breaks down

How the black triangle pool breaks down

  • Classic solid black triangle string sets
  • Push up and lace builds on the black base
  • High neck cross back high cut ribbed sets
  • Tie dye and polka dot reads on the black triangle
  • Strappy ruched Brazilian builds in black
  • Floral print push up halter on the black base
Styling a black triangle set

Styling a black triangle set

  • Black is the base of the outfit — one accent color on top and the set reads complete
  • White is the classic partner; gold hardware is the evening read
  • Off the beach, a black triangle top under a white shirt reads as the base layer
  • When the set carries a print on the black base, keep the accessories solid
Caring for black swimwear

Caring for black swimwear

  • Rinse after the water — black dyes settle in the fiber in the first few swims
  • Dry in shade; the deep black holds heat and shifts under sun
  • Keep black sets away from white and pastels when damp; the dye carries at the edge
  • Check the lace and the push up builds at the edge after each wash; the finished edge takes the wear

Frequently asked questions

Is the whole pool solid black?
The pool tracks the black family — the solid black triangles plus the black base builds that carry a print or a colorway. The product page shows the exact read of each style.
How many black triangle styles are in the store?
108 styles, about $17 to $59 — the widest pool in the black family of the store.
Will the black fade?
Black shifts under heavy sun and chlorine use, usually toward a softer tone rather than grey. Rinse after the water, dry in shade, and keep the set away from light fabrics when damp.
Does the push up build support in the water?
The push up is the panel construction of the cup — the shaping comes from the cut and the gather, not a wire. The underwire builds in the store are the alternative for the structured shape.
