Keyhole Bikini Top

What a Keyhole Is

A keyhole is a small, enclosed opening in the fabric — cut as a compact shape with fabric all around it, rather than an open edge. The name comes from the resemblance to a lock’s keyhole. In swimwear it most often appears at the front of a halter top, just below the neckline, as a single small cutout.

This collection holds 22 styles from about $17 under the keyhole label. The honest note: the label runs loose, and wider cutout and hollow styles sit alongside true keyhole pieces — each listing’s photos show the actual opening.

Keyhole vs Cutout

• Keyhole: a small, enclosed opening
• Cutout: any intentional opening, any size
• Hollow-out: open-space styling along edges

Keyhole is a specific member of the cutout family. Cutout is the general word for any intentional opening — the store’s cut out collection carries that full range. Keyhole narrows it to the small, enclosed shape. Hollow-out styles open space along edges rather than cutting a closed shape.

Where Keyholes Sit

The classic keyhole position is the front of a halter top — a small opening below the neckline where the two sides of the top meet. The cut is decorative: it opens the line of the top in a controlled point, and the enclosed shape keeps the fabric stable around it.

The placement matters for fit — the opening sits above the band, so sizing by the chart keeps the top’s structure sound. The keyhole itself is a seam-finished detail on standard swim construction.

What This Pool Carries

The 22 styles under this label mix true keyhole pieces with wider cutout neighbors: metallic keyhole-cutout halters and one-pieces carry the enclosed shape, while strappy cutout and tie-up styles round out the pool with larger openings.

Because the label runs loose, shop by the opening you want — small enclosed keyhole for the classic read, wider cutout if that is the look — and confirm the shape on the listing photos.

Styling and Caring

A keyhole reads as a precise detail — the small opening adds a point of interest without dominating the top. The cut works with clean styling, and the enclosed shape keeps the fabric secure around the opening.

Care follows the fabric: rinse after salt or chlorine, wash gentle, dry flat. The keyhole edges are seam-finished — standard swim care keeps the opening clean.
