How many pairs of maternity underwear do I need?

How many pairs of maternity underwear you need will differ for each person. You might consider how often you want to do laundry and whether your pre-pregnancy underwear will be suitable for some days or occasions. Then, get as many pairs as you need to have enough between laundry days.

How do I wash maternity underwear?

You can either hand wash your maternity underwear or wash them in your washing machine. With many brands, either method will work. However, take a look at the product label for specific instructions for the pairs you purchase.

Do you go up in underwear size while pregnant?

Typically, you should still wear the same size in maternity underwear as you do in regular underwear. However, some people may want to go up a size to allow more room to grow. Note that each brand is different, so consult the sizing chart to ensure you get a good fit.

The 10 Best Pairs of Maternity Underwear of 2023

The weeks pregnancy are an exciting and ever-changing time for your body. As your belly grows, maternity clothes become essential for every day comfort. While some of your regular underwear may continue to fit, maternity underwear is made to fit the shape of a growing, pregnant belly so it’s better suited to your changing body.

If you’re ready to make the switch to maternity underwear, it’s important to choose a style and size that is right for you. Most maternity underwear sits over the bump, under the bump, or right on the baby bump. Just like regular underwear, maternity undergarments come in various cuts and styles, from boy shorts to thongs. When searching for the perfect pair of maternity underwear, prioritize comfort to accommodate your changing body.

To find the best maternity underwear, we considered comfort and versatility. We looked at various styles and size options, and considered different fabrics—particularly those that are breathable and stretchable—so the undergarments will last. Some pairs on our list are even suitable for postpartum recovery.

Based on our reviews, these are the best maternity underwear on the market today.

Reviewers sing the praises of these seamless, high-waisted mesh panties. Praised for “holding it all in” and providing lots of support without being too snug, these are well worth the higher price tag.

Stretchy, smooth, and comfortable, these pairs are made from 72% bamboo (plus nylon and spandex), creating a breathable and soft fabric. The lightweight undies provide full coverage and a crossover waistband that sits below the belly.

Reviewers note these are also a great style option for postpartum wear and for those with a C-section scar since the waistband is just low enough that it won’t bother your healing skin.

A boy short style provides extra coverage in the hips and bum and will stretch to fit a changing body. While two colors are available, each three-pack only has one color, so you can’t vary colors.

As with most things pregnancy-related, the 4th trimester is a time of transition. After childbirth, postpartum bleeding can continue for several weeks. Once the heavier flow stops, you may feel more comfortable with some period panties, so you’ll have leakproof protection all day long.

Lace panels add an extra flair of style, while the striped elastic waistband is sporty and practical. Sizing ranges from XS through 1X, so you can find the postpartum size that works for you.

For an under-belly style, these maternity panties fit low but don’t place any pressure on your body. Low cut, they’re made from a cotton/spandex blend.

What to Look for in Maternity Underwear

Style

There are maternity underwear styles out there for every pregnant person's needs. In fact, during pregnancy, it’s easy to maintain your current style, just in a more comfortable way. Just like the underwear you normally buy, the style of maternity underwear that you choose should be comfortable for your body type. When it comes to accommodating your growing bump and changing body, there are two main types of underwear.

Over the belly: This type of underwear, as the name would suggest, has a stretchy panel that covers and supports your bump. Some can have built-in, light compression, or just a breathable panel.
Under the belly: Designed to rest around your hips and underneath your bump, this type of maternity underwear may be ideal during warmer months or underneath fitted clothing.

Beyond belly coverage, maternity underwear is available in a variety of cuts like bikini, boy short, and even thong. Try a few styles since your comfort level may change as your belly grows. If you have a special event or specific need, invest in one or two pairs that meet that need.

Sizing

It can be tricky to determine the right size for maternity underwear, especially when it feels like your body can change dramatically overnight. Check each brand’s sizing recommendations, but most pregnancy underwear (and maternity clothes in general) use sizing based on your pre-pregnancy size.

Depending on where you are in your pregnancy, you may choose to purchase a few different pairs of maternity underwear in various sizes to accommodate your growing bump throughout your pregnancy.
