Best Maternity Swimsuits of 2020

Find a maternity bathing suit you'll actually want to wear.

If you don’t live in a hot climate or visit the beach on the regular, you might not place maternity swimwear high on your shopping list.

But the bigger your baby bump gets, the more you deserve to show it off — and, the more you can probably benefit from jumping in a pool of water. Swimming can not only help you cool off, but it also offers your joints some relief.

There are tons of reasons you might need to wear a swimsuit while pregnant, but with all of the options, it’s hard to figure out which one might work for you. Here’s what you need to know to find the best maternity swimsuit for you.

Why Do I Need a Maternity Swimsuit?

You might not think that you need maternity swimwear, or that it would be easy to go through your pregnancy without it.

However, there are probably more opportunities to wear it than you realize, including:

  • Cooling off when the weather is hot — a dip in the backyard kiddie pool is refreshing during summer.
  • Wearing on family vacations even if it’s not to a hot-weather destination; hotels have pools.
  • Playing with or chasing your kids at the beach during summer.
  • Relieving back and other joint pressure by floating or swimming (1).
  • Wearing during childbirth — even if you don’t plan a water birth, many hospitals have soaking tubs for pain relief during labor.

You might be tempted just to wear your old pre-pregnancy bikini since it goes below the belly and you could probably make it work to cover your nether regions.

And we get it — it can be hard to cough up money for such a restricted-use wardrobe item when you’re preparing for all the other expenses related to having a baby.

However, there are many reasons you really should consider a swimsuit designed for the pregnant body.

  • It will be more comfortable.
  • You will be more confident as there will be less chance of a “wardrobe malfunction.”
  • Your breasts will grow during pregnancy, making the fit more awkward.
  • Your hips will spread during pregnancy, potentially making your previous bottoms too small.
  • A well-designed maternity one-piece or over-the-belly two-piece can provide extra support to your belly weight, helping to relieve pressure on your back.

Types of Maternity Swimwear

Maternity bathing suits come in all different types and styles, just like regular swimwear. Popular styles are:

  • One Piece: This is the standard swimsuit, but with more fabric in the front to accommodate a swollen belly.
  • Over-the-Belly: For moms who want to flaunt their baby bump, the high-waisted swimsuit is back in style and is totally being manufactured to fit over a baby bump. This is a two-piece suit that has a bikini top but a full-coverage bottom.
  • Maternity Tankini: The maternity tankini has a full-coverage top but bikini bottom. This style offers the convenience of a two-piece (hello, bathroom breaks!) with the coverage of a one-piece. They also tend to be less tight across the belly.
  • Bikini: This is the style for the mom who wants to show off her full baby bump and breasts, this is an option for the confident mom — and also the one who wants as little fabric touching her middle as possible.

How to Choose the Best Maternity Swimsuit

When buying the best maternity swimwear, look for the following:

  • Style: Mama, this is YOUR time. Don’t worry about what other people think you should wear — you wear what makes you feel comfortable. And if that’s a full-coverage, high-necked one-piece, rock it. And if it’s a string bikini, do the same.
  • Leg Opening: If you’re short or self-conscious about your thighs, choose a high-legged opening to elongate them. If modesty and full bum coverage is your primary concern, choose one with a lower leg opening.
  • Room to Grow: We know that this is a maternity swimsuit so its lifespan is limited, but you don’t want to have to buy a new one every two months. Buy maternity swimwear that can accommodate your growing belly, expanding breasts, and widening hips throughout your pregnancy.
