Best Maternity Bikinis of 2026: Supportive, Adjustable and Bump-Friendly

When it comes to planning a beach trip while pregnant, there’s no need to feel intimidated where swimwear is concerned. Whether you’d like to sun your growing belly in something skimpy or cover up with a supportive one-piece, there’s a swimsuit on the market for you.
Regardless of whether you’re planning for your first child or your fourth, the last thing you have time to do is research swimsuits for your upcoming family vacation, so we did the hard work for you. Below, learn more about the best maternity bikinis on the market and shop a few SI Swimsuit-approved picks.

Are maternity swimsuits a thing?
Yes! Maternity swimsuits are definitely a thing. While you can always size up to accommodate your growing belly and rock, say, a string bikini, maternity swimsuits are made specifically for your changing figure. They’re designed to be worn throughout the duration of your pregnancy so you can hit the pool without worrying about your wardrobe.
Oftentimes, maternity suits are made out of stretchy fabric and feature ruching around the belly, built-in support at the bust, and adjustable straps so you can find something that fits (and can be continually adjusted) throughout your pregnancy.
What kind of swimsuit should I wear while pregnant?
Whatever you’re comfortable in! Anything goes, and it’s all up to your personal sense of style. While some women may be more comfortable baring their bump in a tiny two-piece, others may seek out a more supportive garment, like a one-piece with underwire.
