Hunza G Square Neck one-piece swimsuit in black

The Best One-Piece Swimsuits for Every Body (and How to Choose Yours)

The one-piece has quietly become the most versatile piece in a summer wardrobe, as at home under linen trousers at lunch as it is in the surf. With so many silhouettes on offer, choosing the right one comes down to fit, fabric and how you plan to wear it. Here is our guide to the best one-piece swimsuits, drawn from the swim labels we curate at Tuchuzy.

For a flattering, fuss-free fit: Hunza G

If sizing stress is your issue, Hunza G solved it. The brand's signature crinkle fabric stretches to a true one-size fit (UK 6 to 18), sculpting and holding without boning. The square-neck and scooped-back styles are modern classics. In stock now, the Hunza G Square Neck Swim Black is the one-and-done that styles under everything, while the Hunza G Pamela Swim Black gives you a softer neckline in the same forgiving fabric. For a warmer tone, the Hunza G Domino Swimsuit Blush is the blush one-piece we keep restocking.

For sculpting and support: Montce

Prefer structure? Montce Swim cuts flattering, fashion-forward silhouettes with real support, ideal if you want a piece that holds its shape from pool to bar.

For sustainable style: Fae Swim

Made from regenerated ECONYL nylon, Fae Swim proves a conscience and a cult fit can coexist. If you would rather build your own from a mix-and-match set, the in-stock Fae Swim Honey Bikini Top Lilac is the easy way in. A note: Fae runs small, so size up.

How to choose your one-piece

  • Neckline: a plunging or square neck elongates; a high neck feels sporty and covered.
  • Back: a scooped or open back adds drama and keeps tan lines minimal.
  • Fabric: look for stretch that recovers its shape and holds up to salt water.
  • Versatility: the best one-piece doubles as a bodysuit under skirts and trousers.

Style it beyond the beach

Tuck a one-piece into wide-leg linen trousers or a wrap skirt and you have an instant going-out top. That is the quiet genius of the style.
