One piece swimsuit

Why Choose a One-Piece Swimsuit During Pregnancy?

When warmer days arrive, nothing beats a well-designed one-piece maternity swimsuit for enjoying the sea, pool or sunshine during pregnancy. Offering more coverage and reassurance than a bikini, this type of swimsuit provides an ideal balance of style, comfort and UV protection. At Cache Cœur, we have created swimsuits designed to support moms-to-be through every movement while flattering their changing silhouette. Available in a range of sizes and colors, they adapt to different styles and body shapes.

Complete Comfort During Pregnancy, Even at the Beach

A growing bump, a more sensitive bust… pregnancy changes your needs, including when it comes to swimwear. Our swimsuits are made from soft, stretchy fabrics that provide genuine freedom of movement. They do not feel tight or dig into the skin and gently adapt to your curves, allowing you to swim, walk or relax without restriction.

Reliable Support for Your Changing Body

During pregnancy, your body can change quickly. Good support, especially around the bust, becomes essential. Adjustable straps, built-in cups and carefully designed backs… every piece in our collection has been created to combine support with femininity. The result: you feel comfortably supported without ever feeling restricted.

Coverage Designed for Pregnancy

One-piece swimsuits are ideal for women looking for a little more coverage, particularly around the bump. They also provide excellent sun protection thanks to our certified UPF 50+ UV-protective fabric. All our styles are also OEKO-TEX Standard 100 certified, offering greater peace of mind even against the sensitive skin of moms-to-be.

How to Choose the Right One-Piece Maternity Swimsuit

Choosing a swimsuit for pregnancy means considering comfort, fit and how you plan to wear it. Here are our tips to help you choose the right style for your needs.

What Size Should You Choose for a Maternity Swimsuit?

Good news: at Cache Cœur, there is no need to size up. Our styles are designed to adapt to your pregnancy curves. Simply choose your usual clothing size. A size guide is available to help you, and if you are unsure, reviews from other moms can also provide useful guidance.

The Best Fabrics for Pregnancy and Swimming

Fabric choice makes a real difference when it comes to comfort. Our swimsuits are made from soft technical fabrics designed to withstand chlorinated and salt water, with some styles even incorporating recycled fibers. This allows us to offer more eco-conscious pieces—an added benefit during pregnancy.

A Fit Designed for Your Growing Bump

With carefully placed seams and ruching designed to adapt as your body changes, each style follows your curves without restricting them. Some designs feature slightly lower necklines, while others provide more coverage, with details that combine style and comfort. You are sure to find a swimsuit that flatters your silhouette.

Beach, Pool or Spa: A Swimsuit for Every Occasion

Whether you are planning to swim laps, spend a day at the beach or enjoy a relaxing spa break, our maternity swimsuits are designed for every occasion. Some styles even allow for discreet breastfeeding thanks to easy-access openings. You can also pair your swimsuit with other pieces from our collection, such as lightweight dresses, skirts or flowing tops, for a complete look.
