                                Why Choose a One-Piece Maternity Swimsuit?

                                When the warm days arrive, nothing beats a well-designed one-piece maternity swimsuit to enjoy the beach, pool, or sun during pregnancy. More covering and reassuring than a bikini, this type of swimsuit strikes the perfect balance between style, comfort, and UV protection. At Cache Cœur, we design one-piece swimsuits that support moms-to-be in every movement while flattering their changing silhouette. Available in multiple sizes and colors, they adapt to every body shape and preference.

                                Comfort at the Beach Throughout Pregnancy

                                As your belly grows and your bust becomes more sensitive, your needs evolve—even when it comes to swimwear. Our swimsuits are made from soft, stretchy fabrics that ensure complete freedom of movement. They don’t pinch or dig in, instead adapting naturally to your curves so you can swim, walk, or relax without restriction.

                                Support for Your Changing Body

                                During pregnancy, the body changes quickly. Proper support—especially for the bust—is essential. With adjustable straps, integrated cups, and carefully designed backs, each piece in our collection combines comfort and femininity. The result: you feel supported without ever feeling compressed.

                                Coverage Tailored for Pregnancy

                                One-piece maternity swimsuits are perfect for moms-to-be seeking more coverage, especially around the belly. They also provide excellent sun protection thanks to our certified UPF 50+ fabric. In addition, all our swimsuits are OEKO-TEX Standard 100 certified, guaranteeing safety even against sensitive skin.

                                How to Choose the Right One-Piece Maternity Swimsuit?

                                Selecting the right swimsuit during pregnancy means thinking about comfort, fit, and functionality. Here are our tips to help you make the best choice.

                                What Size Should You Choose?

                                Good news: with Cache Cœur, you don’t need to size up. Our swimsuits are designed to adapt to your pregnancy curves. Simply choose your usual ready-to-wear size. A detailed size guide is available, and customer reviews from other moms can also help you decide.

                                The Best Fabrics for Swimming and Pregnancy

                                The choice of fabric makes a big difference in comfort. Our swimsuits are made from technical, soft, and durable materials resistant to chlorine and salt water—sometimes even crafted from recycled fibers. This makes them both eco-friendly and pregnancy-friendly.

                                A Fit That Grows With Your Belly

                                With side gathers and smart cuts, each design adapts to your body without compressing it. Some models feature slightly plunging necklines, others offer more coverage, with details that combine style and comfort. You’re sure to find the one that best flatters your silhouette.

                                For the Beach, Pool, or Spa: A Swimsuit for Every Occasion

                                Whether you’re swimming laps, enjoying a beach day, or relaxing at the spa, our maternity swimsuits are designed to suit every situation. Some models even allow for discreet nursing thanks to practical openings. You can also pair your swimsuit with other pieces from our collection—light dresses, skirts, or flowy tops—for a complete summer look.
