A selection of some of the best maternity swimsuits

We include products we think are useful for our readers. If you buy through links on this page, we may earn a small commission. Here’s our process.

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 have the lowdown on whether you need a maternity suit or not, and some cute picks if you decide to get one.

The 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.

“If you don’t like investing in a large maternity wardrobe, this might be the way to go as you can still wear a bikini after you have a baby.”

It is not possible for other types of swimsuits, especially when you are in your third trimester. The fit of a tankini is not meant to accommodate an expanding belly, so it is not going to be an option that you can pull from standard sizes.

If you are a style person, you will want to look for a maternity swimsuit.

We found a few selections that we think are going to be great for your next beach vacation or day at the pool. We wanted to poll our Healthline family for their top recommendations. We chose maternity suits that were comfortable.

  • 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.

You should consider the fit, material, price, design, and style when shopping for maternity clothing.


Depending on the store you choose and the style, prices can vary. A simple, solid-colored two-piece will not suffice for more intricate styles.


“If you want to get the most bang for your buck, you need to consider the fit. If you are shopping from standard sizes, look for bottoms that have a different style of tie so you don’t have to buy more bottoms as your belly grows.”

A good tankini is the best option for the second and third trimesters, while a supportive halter style is the best for the fourth and fifth trimesters.

“Sometimes the fit of a one-piece can be difficult. If you find that your search for the perfect one-piece isn’t working, you should move on to a two-piece instead.”


You can find a maternity swimsuit in the same sizes as a standard-sized swimsuit. That includes swim dresses, bikinis, and swim bottoms. There is no right or wrong choice here, as long as you pick something that you feel good in!


“You are pregnant, that doesn’t mean that your sense of fashion has gone out the window. You want a swimsuit that reflects your personality and style, just like before you got that BFP. Maybe you prefer solid colors over patterns, or maybe you like side-tie bikinis with fun accents on the strings. The sky is not the limit, mama.”

What size maternity swimsuit should I buy?

The swim style you pick will affect the size of your swimsuit. The most forgiving is the bikinis 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. If you choose to wear roll-down bikini bottoms, it is best to choose a maternity size as these will accommodate a growing babybump.

You can still shop your regular size with maternity sizing. The design features like ruching and paneling are meant to accommodate your babybump. The bust area may be a little more generous as pregnant women tend to increase their bra size by a few cups.

Can you buy normal swimwear while pregnant?

Only for certain styles. If you focus on under-the-belly bikinis, you can get away with buying regular-size swimwear. You may be able to size up in some styles. Your breasts may be larger. 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.

It can feel like a catch-22 if you want to stay stylish while not overspending for 4 to 5 months of maternity fashion. A good maternity swimsuit can help you transition into early postpartum. If you like bikinis even when you have a baby, those babies can last a lifetime.
