Planning a vacation somewhere tropical? Let’s talk maternity swimsuits. The best maternity swimsuits will help you look and feel confident at the pool, beach or on your babymoon. While you can get away with a regular bathing suit during the first trimester, a purpose-built pregnancy bikini or swimsuit is well worth the investment. Maternity swimwear is designed with your changing body in mind, and boasts practical features such as ruching that stretches to accommodate your bump, adjustable straps and built-in shelf bras to support your growing bust. And most maternity bathing suits are made from super-stretchy, quick-drying fabrics, which is a major plus point. (Trust us, anything tight or restrictive is a no-no.) Remember, your skin is super-sensitive during pregnancy so it’s best to opt for a maternity bathing suit made with UPF 50+ material that’ll shield your skin from sun exposure.

The good news? There’s plenty of stylish maternity bathing suits to choose from. Whether you’re an active mama looking for a high-performance swimsuit or a beach babe that likes to bare the bump in a colorful bikini, there’s a style out there for you. But to save you extra trips to the dressing room (or multiple online shopping returns), we’ve curated a list of the best maternity swimsuits around. From maternity tankinis and bikinis to one-pieces and more, we’ve found the cutest maternity swimwear styles to suit any mom-to-be.

How We Chose the Best Maternity Bathing Suits and Bikinis

Finding a swimsuit can be tricky at the best of times—add a baby bump to the mix and it may feel nigh on impossible. The good news? The Bump team is here to help. To streamline your decision-making process, our goal is to do the bulk of the research for you, so you don’t have to spend hours scrolling through online retailers. We do this by considering a list of criteria when sourcing pregnancy-friendly swimsuits, including quality, material, value, style and stretch-factor. This way you can count on getting the best bang for your buck, while also having a flattering swimsuit that meets your needs.

To decide which pregnancy swimsuits are the best options on the market, we leverage our familiarity with leading maternity brands to make sure items are from reliable manufacturers. We read user reviews to get the low-down on how these products work for moms, and typically don’t consider anything with less than an average four-star rating.
