Hollow Out Bikini

What Is a Hollow Out Bikini?

A hollow out bikini is a bikini with cutouts — sections of fabric removed so the openings are part of the design. “Hollow out” and “cutout” are two names for the same construction: deliberate openings in the fabric at the waist, sides, back or chest.

The detail travels across garments: hollow-out bikini tops and bottoms, one-pieces and monokinis with cutout sides, and even cover-ups and beach dresses with openwork panels. In this collection it also picks up crochet and lace openwork, which create the same look with texture.

Hollow out is an opening in the fabric — different from sheer, which is a see-through material.

Where Cutouts Sit and What They Do

Cutout placement shapes the look more than the cut itself:

• Waist and side cutouts — openings along the torso or hip on sets and one-pieces.
• Back cutouts — openings across the back, from straps to deep scoops.
• Chest and strappy cut-outs — openings framed by thin straps across the top.
• Openwork texture — crochet, lace and netting create hollow-out effects in the fabric itself.

Cutouts are a style element, not a coverage shortcut — the openings sit where the design places them, and coverage around them is set by the rest of the piece. Read the photos to see exactly where the openings run.

Placement sets the look; the panels around the openings set the coverage.

The Styles in This Collection

Hollow-out styles show up across these silhouettes:

Pick the opening placement first, then the garment.

Wearing and Fit

Cutout edges are finished with elastic or binding, and that edge does the holding work — it should sit flat without gaping or digging. Sit-test the fit before active days, since openings change how a piece moves with you.

Care follows the fabric and the finish: hand-wash in cold water, and be careful with openwork and crochet — the openings snag easily on jewelry or rough surfaces. Dry flat to keep the cutout edges from warping.

Edges flat, sit-test before sports, gentle wash for openwork.

How to Choose

Work through four decisions:

• Opening placement: waist, side, back or chest
• Garment: set, one-piece, monokini or cover-up
• Texture: smooth cutout, lace or crochet openwork
• Coverage around the openings: fuller or minimal

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