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 suit.

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 aren’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 criteria above, we found a 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 Healinggeeks family for top recommendations. We chose maternity suits based on:

  • Style. Just like with your pre-baby body, everyone has different tastes. There are a wide range of options from under-belly to over-belly bikinis, one-pieces, and tankinis or monokinis.
  • Size. We made sure brands included offered a wide range of sizes.
  • Color: You can’t go wrong with black, but there’s a wide range of options out there. From bold solids to bright prints, we don’t feel like you have to be limited just because you’re rocking an outfit for two.
  • Price. Some people want to splurge, others want to save. So we included maternity swimsuits across the spectrum to accommodate a variety of budgets.

Much like when you’re shopping for other maternity clothing, you’re going to want to consider the fit, material, 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 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 side-tie bikinis with fun accents on the strings. The sky’s the limit, mama.

What size maternity swimsuit should I buy?

Picking the right size for your swimsuit is going to depend on the swim style you pick. Bikinis tend to be the most forgiving because you can usually buy your pre-pregnancy size, which means you can continue shopping from standard-sized lines rather than focusing solely on maternity collections. However, if you opt for roll-down bikini bottoms, it’s best to focus on maternity sizes as these will feature ruching that accommodates a growing bump.

With maternity sizing, you can still usually shop your regular size. However, you’ll find that the design features like paneling and ruching are intended to accommodate your bump. Likewise, the bust area may also be a little more generous, as pregnant women tend to increase their bra size by anywhere from one to three cups.

Can you buy normal swimwear while pregnant?

Yes, but only for certain styles. Typically, you’ll only be able to get away with buying regular-size swimwear if you focus on under-the-belly bikinis. In some styles, you may simply be able to size up. Keep in mind that your breasts may be larger. So, if you want to focus on regular sizes, look for mix-and-match swimwear that allows you to shift up or down in size for tops so that you can accommodate your growing bust line.

What are the best maternity swimwear brands?

Best is always subjective and will also depend heavily on your budget. If you’re shopping on a budget, most mass retailers like Target, Old Navy, and H&M will be great options that are affordable but still offer stylish and durable solutions that can last more than a handful of uses. If you have more flexibility in your budget, brands like Seraphine and PinkBlush offer great maternity styles that are moderately priced. And if budget is no issue, premium brands like Hatch are fantastic at offering fashion-forward solutions for outfitting your bump.

Maternity fashion can feel like a catch-22 as you try to find a happy medium between staying stylish and not blowing through your budget for ultimately 4 to 5 months of bump fashion. But a good maternity swimsuit should be able to transition with you at least into early postpartum. And if you’re a fan of bikinis even when you’re sporting a bump, those babies can last a lifetime!
