GirlsMustHave plain colour swimwear highlights what matters most: the cut, the line and the silhouette. Without a print, everything relies on the precision of the design, the quality of the fabric and the balance of proportions. It is this apparent simplicity that gives these pieces their strength.

A graphic black one-piece, an ivory bustier, a bikini in a deep or sunlit shade: plain colours create a purer, more timeless look, while remaining distinctly feminine. They reveal the brand’s work on cut and allow the fabric to stand out at its best: an Italian fabric with a silky finish and a sculpting effect.

Designed to last and to be worn season after season, our plain colour swimwear can be discovered through our one-pieces, our two-pieces and our Summer 2026 Collection. For a more expressive approach, you can also explore our prints and our stripes.
