Plus Size Swimwear

At Sans Complexe Paris, we believe every body deserves swimwear that truly fits. Our plus size swimwear collection for women is designed for comfort, support and style, from size 12 (UK) upwards, with special attention to fuller busts and curvier figures. One-piece, two-piece, high-waisted or shaping: every cut is designed to flatter without compromise.

Why the Right Plus Size Swimwear Makes All the Difference

Ill-fitting swimwear can quickly ruin your summer. Too loose, and it won't support the bust; too tight, and it digs in and compresses. That's why our styles for curvier women are designed from the ground up with structured cups, adjustable straps and stretch fabrics that move with the body instead of fighting it.

Our team has specialised in plus size lingerie and swimwear for many years, with one constant standard: cuts that are genuinely tested on fuller, curvier figures, not simply scaled-up standard patterns. The result is swimwear that holds up at the beach and in the water, season after season.

Our Plus Size Swimwear Collection

Whether you prefer the simplicity of a one-piece or the flexibility of a mix-and-match set, our range covers every preference.

Plus Size One-Piece Swimsuits

The plus size one-piece swimsuit remains a safe choice for anyone looking for support with elegance. Tummy-control panels, flattering necklines, swim-back or plunge-back styles: these designs shape gently while staying flattering. It's often the most reassuring first step into plus size swimwear, especially for pear or hourglass shapes.

Plus Size Bikinis (Two-Piece Swimwear)

Want more freedom, or need to mix top and bottom sizes? Plus size bikinis let you choose cup size and bottom size independently — a real advantage when bust and hips don't grow at the same rate. Underwired bikini tops, draped tankinis or bralette-style tops: each cut offers a different level of support. If you'd rather cover more of the tummy while keeping it stylish, a plus size tankini is an excellent middle ground between bikini and one-piece.

High-Waisted and Shaping Swimwear

High-waisted plus size swimwear is loved for its natural shaping effect: it defines the waist, supports the lower tummy, and pairs well with either a bikini or tankini. Our shaping plus size swimwear features strategically placed technical panels for an instant smoothing effect without excessive compression. Discover our dedicated High-Waisted Bikini Bottoms for Women range to complete your favourite top.

How to Choose the Right Plus Size Swimwear

Choosing the right plus size swimwear comes down to two key things: bust support and overall fit.

Which Style for a Fuller Bust (Cup Size)

For a fuller bust, choose a style with underwire or reinforced, adjustable straps, which distributes the weight of the bust more evenly and stops straps from slipping. Balconette and full-cup tops, already trusted in bras, are also available in full bust swimwear styles — offering a natural shape and optimal support, even for larger cup sizes.

Choosing Your Size (Size Guide)

The right size depends on both your bust and back measurements, as well as your lower body shape, which can vary independently. If in doubt between two sizes, it's best to go up a size for comfort, especially with a one-piece. To avoid ordering mistakes, check our swimwear size guide before choosing.
