Maternity one-piece swimsuit

Why choose a one-piece maternity swimsuit?

When sunny days arrive, nothing beats a well-designed one-piece swimsuit to enjoy the sea, the pool, or the sun during pregnancy. More covering and reassuring than a bikini, this type of swimsuit offers an excellent balance between style, comfort, and UV protection. At Cache Cœur, we’ve designed swimsuits to accompany expectant mothers in all their movements while flattering the figure. Available in various sizes and colors, they adapt to all preferences and body types.

Absolute comfort during pregnancy, even at the beach

The growing belly, sensitive breasts… being pregnant changes your needs, even for swimwear. Our swimsuits are made from soft and stretchable fabrics that provide true freedom of movement. They don’t pinch or leave marks and follow your curves gently, so you can swim, walk, or relax without constraints.

Good support to accommodate your changing body

During pregnancy, the body changes quickly. Proper support, especially for the bust, becomes essential. Adjustable straps, built-in cups, detailed backs… each piece in our collection is designed to combine support and femininity. The result: you feel well-supported without ever being compressed.

Coverage suitable for pregnancy

One-piece swimsuits are perfect for those looking for a bit more coverage, particularly around the belly. They also provide excellent sun protection thanks to our UPF 50+ certified fabrics. All our swimsuits are also OEKO-TEX Standard 100 certified for optimal safety, even against sensitive skin of expectant mothers.

How to choose the right one-piece maternity swimsuit?

Choosing a swimsuit for pregnancy means thinking about comfort, fit, and use. Here are our tips to help you select the right one according to your needs.

Which size to choose for a maternity swimsuit?

Good news: at Cache Cœur, there’s no need to size up. Our models are designed to fit the curves of pregnancy. Simply follow your usual ready-to-wear size. A size guide is available to help, and if in doubt, reviews from other moms provide useful insights.

The ideal fabrics for pregnancy and swimming

Fabric choice greatly affects comfort. Our swimsuits are made from soft technical fabrics, resistant to both chlorinated and salt water, and sometimes even include recycled fibers. This allows us to offer more eco-friendly options—a welcome bonus during pregnancy.

A cut adapted to your growing belly

With cuts and ruching designed to evolve with your body, each model hugs your curves without compression. Some designs are slightly plunging, others more covering, with details that balance aesthetics and comfort. You’re sure to find the one that flatters your silhouette.

Beach, pool, or spa: a swimsuit for every use

Whether you plan to swim lengths, enjoy a day at the beach, or relax at a spa, our maternity swimsuits adapt to every situation. Some models even allow discreet breastfeeding thanks to an easy-access opening. You can also pair your swimsuit with other items from our collection: light dresses, skirts, or flowing tops for a complete look.
