Considering that pregnancy lasts for 9 months, depending on when you conceived, there’s a strong chance that you’ll be pregnant during the summer months. Or, you might decide to take a babymoon to a warm spot before your bundle of joy arrives.

Whichever scenario applies, if you’re pregnant and planning on hitting the beach or pool, you’re probably wondering whether you should just size up in a standard-sized swimsuit or if you should opt for a specially designed maternity swimsuit.

We’ve got the lowdown on whether you need a maternity suit and some cute picks if you decide to snag one!

The tl;dr (too long; didn’t read) answer is, it depends on the style you pick and where you are in your pregnancy.

With a traditional bikini that features a bra top and a simple underwear bottom, regardless of what pregnancy stage you’re in, you can probably make do by simply going up a size to accommodate your growing bust.

And if you’re in the camp that isn’t a fan of investing in a large maternity wardrobe, this might be the way to go as you can still wear that bikini even after you have your baby.

The same can’t be said for other types of swimsuits, especially once you enter your third trimester. Specifically, any one-piece or bikini style with a longer top — such as a tankini — isn’t going to be an option that you can pull from standard sizes as the fit isn’t meant to accommodate an expanding belly.

So, if one-pieces, tankinis, or swim dresses, are your style, you’re going to want to look for a maternity swimsuit.

Using the same criteria we recommended above, we came up with a few selections that we think are going to be a great fit for your next beach vacation or day at the pool. We also made sure to poll our Healthline family for top recommendations.

Best maternity one piece

Seraphine Front Twist Black Maternity Swimsuit

Price: $$

Like we mentioned earlier, one-piece maternity swimsuits can be tricky because the fit through the torso varies between moms-to-be. But this pick from the very-trendy Seraphine offers ample room in the belly (thanks to the ruched sides) without compromising on style.

You’ll appreciate the front twist in the bodice along with the metal ring accents at the straps, and the cross back for a fun and sporty look. Plus, as is common with maternity swimwear, the bottom offers modest coverage.

Best maternity two-piece

The Maternity Ribbed Voyager Top and Classic High-Rise Bottom from Summersalt

Price: $$$

This Summersalt cross back halter bikini top still gives you plenty of coverage, while the adjustable straps mean that you can use this top for every stage of your pregnancy. You’ll also appreciate the built-in cups to give your girls added support — which will come in handy — along with the microribbed fabric for added gentle compression.

The Classic High Rise bottoms are exactly what they sound like — the same ribbed material in a high-rise cut that shows just a peek of bum. Fans of this suit say they love that the elastic doesn’t cut into their bump and that the suit is true to their pre-pregnancy size.

Likewise, the adjustable bikini bottom means you can create a few different looks. When you feel like showing off your growing bump, wear the bottoms low. Or, raise the band for an over-the-belly look.

Best basic black maternity swimsuit

Old Navy Maternity Halter V-Neck One-Piece Swimsuit

Price: $-$$

For the mama who wants something simple, you can’t go wrong with Old Navy. This budget-friendly solution still gives you a bit of style thanks to the tie accent at the bust and the halter design.

If you’re torn between a one-piece and a bikini, a maternity tankini should give you a good blend of flexibility and coverage where you want it.

Best splurge maternity swimsuit

Hatch Mallorca Maillot One-Piece

Price: $$$$

If money is no object, then you need to make a beeline to Hatch to shop for a maternity swimsuit. Their Mallorca Maillot is a one-piece swimsuit with color block accents that’s available in two colorways. It’s a truly modest pick that’s ideal for the third trimester, while still playing up fun elements with the functional tie accents at the shoulders.

You’ll get plenty of support thanks to the built-in shelf bra and ruched seams at the bust and in the torso. The back also has a fun scoop and the fabric also contains UPF 50+.

Much like if you’re shopping for other maternity clothing, you’re going to want to consider the fit, the material, the price, design, and style.


With maternity clothing, prices can vary widely depending on the store you select and the style. More intricate styles will understandably cost more than a simple, solid-hued two-piece.


If you’re looking to get the most bang for your buck beyond simply focusing on the price, you need to consider the fit. If you’re shopping from standard sizes, look for bottoms that have adjustable ties so that you don’t need to keep buying more bottoms as your belly grows.

And as for the top, a supportive halter style will work through all three trimesters while a good tankini option is best for the second and third trimesters.

If you’re more comfortable in a one-piece, keep in mind that sometimes the fit here can be tricky. Everyone carries their pregnancy differently, so if you find that your hunt for the perfect one-piece isn’t working, move on to a two-piece instead.


You can find a maternity swimsuit in all the same configurations that you would a standard-sized swimsuit. So, that includes one-pieces, two-pieces (i.e. bikinis, tankinis), swim dresses, and swim bottoms. There’s no right or wrong choice here as long as you pick something that you feel comfortable wearing!


You’re pregnant — that doesn’t mean that your sense of fashion has gone out the window. Just like before you got that BFP (big fat positive), you want a swimsuit that reflects your personality and style. Maybe you’ve always preferred solid colors over patterns, or maybe you like tie-side bikinis with fun accents on the strings. The sky’s the limit, mama.
