Keyhole Detail
Keyhole Detail
A small, often teardrop-shaped cutout in a garment, typically at the bust or back, adding a peek-a-boo design element.
What Is a Keyhole Detail?
A keyhole detail is a small, shaped opening cut into a garment — most often a teardrop, oval, or narrow slit — that exposes a controlled glimpse of skin. In lingerie, you will find keyhole cutouts primarily at the center front between the cups, at the centre back below a clasp, or along the neckline of a bodysuit or chemise. The name comes from the shape's resemblance to an old-fashioned door keyhole.
The appeal of a keyhole is its restraint. Unlike plunging necklines or sheer panels that expose larger areas, a keyhole reveals just a sliver of skin — enough to draw the eye without sacrificing coverage. This balance makes keyhole pieces popular for gifting: they feel flirtatious and intentional without crossing comfort boundaries. A back keyhole, for instance, adds an unexpected detail that only reveals itself when she turns around.
In quality construction, the keyhole opening has reinforced edges — often bound with satin tape, sealed with a narrow elastic, or finished with a metal or fabric-covered ring that holds the shape. Poorly made keyholes stretch open, fray at the edges, or distort under the tension of the garment. A well-finished keyhole holds its shape wash after wash and lies flat against the body.
Sinderella places keyhole details where they create the most visual impact — at the décolletage on bra sets and along the back of bodysuits — always reinforced so the shape stays crisp over time.
How to Wear & Style
A front keyhole bra pairs especially well with a slightly open button-down shirt or a deep scoop-neck top, letting the detail peek through intentionally. For a gift, keyhole bodysuits are a strong choice because the cutout adds visual interest while the garment itself provides full coverage and an hourglass silhouette. When washing, fasten any hooks around the keyhole first to prevent snagging.

What is keyhole detail?

Will a keyhole cutout show under my clothing?
It depends on the neckline of your outer layer. A front keyhole at the bust center usually hides under crew-neck or boat-neck tops. Under a V-neck, the cutout may peek through — which can be intentional and attractive. Back keyholes stay concealed under most tops but show beautifully under low-back or racerback styles.
Does keyhole detail affect the support of a bra?
A well-constructed keyhole is reinforced around its edges, so it does not compromise the structural support of the garment. The cutout removes a small amount of fabric from a non-load-bearing area. If the keyhole edges fray or gape open when worn, that indicates poor construction rather than an issue with the design itself.
