There’s no denying that the shape of your body changes during pregnancy. You expect your belly to grow, of course, but your hips also widen to make room for baby—which means you may find yourself in need of new underwear. Instead of simply sizing up on your favorite before-baby undies, consider purchasing some maternity underwear that’s cut just right for moms-to-be. The best pregnancy underwear tends to be stretchier and have a fuller cut, which is just what’s needed when you’re sporting a baby bump.

The good news is that pregnancy underwear comes in lots of different styles, so whether you prefer a thong or a pair of full-coverage briefs, there are plenty of options. Also keep in mind that there are varying cuts available, including over-the-bump and low-rise designs. Comfort is key, so try on a few different styles before stocking your underwear drawer. We recommend grabbing at least one or two pairs that provide full coverage, as they’ll come in handy for the early postpartum days as well (or go ahead and opt for postpartum-specific underwear!). Wondering where to start? We’ve got some tips about how to shop for the best maternity underwear, as well as a list of some of our favorite options.

Types of Maternity Underwear

Maternity underwear comes in many different styles, from bikini briefs to shapewear and even absorbent undies. Like any other type of intimate wear, the option you choose depends on your own personal preference and comfort needs. Here are the three main types to choose from:

  • Under-belly maternity underwear. This type of maternity underwear rests just under your bump and sits low on the hips. Some under-belly styles also feature a crossover design to reduce pressure on your stomach. Women’s health expert Jennifer Wider, MD, recommends looking for “breathable materials, cotton and forgiving waistbands—which most are designed to have.”
  • Over-belly maternity underwear. Also known as high-waisted or over-bump underwear, this type sits just under your bust line, offering full belly coverage. This style of underwear provides gentle support, and some pairs even have built-in compression panels to reduce pregnancy aches and pains. “If you need support with your belly, you may want underwear with a high waist so you feel like it’s tucked in,” says Christine Greves, MD, a board-certified ob-gyn at the Winnie Palmer Hospital for Women and Babies.
  • Absorbent maternity underwear. This underwear typically has special fabric at the gusset (the piece of fabric that comes in direct contact with your crotch) to help lower the risks of leaks. “Up to 70 percent of women may have incontinence in the third trimester,” says Greves. “You might want some with extra absorbency.”

Things to Consider When Shopping for Maternity Underwear

The same factors—quality, cost and cut—come into play whether you’re shopping for regular undies or pregnancy panties. But during pregnancy, fabric choice and sizing concerns play a big role too. Keep the following in mind to find the best maternity underwear for your needs:

  • Fabric: Fabric choice is key when it comes to selecting the best underwear for pregnancy. Some synthetic fabrics, like latex or polyester, trap heat and moisture, which can cause itchiness and irritation. Greves recommends opting for natural fabrics, like cotton or bamboo, as they’re naturally hypoallergenic and breathable. Other materials like rayon and spandex offer great stretch, so it’s okay to wear them as long as the gusset is made from cotton.
  • Sizing: During pregnancy, your body undergoes a rapid transformation in a short space of time, meaning it can be tricky to determine your correct clothing size. In general, you can select your pre-pregnancy size when shopping for maternity underwear. But always check the brand’s size guidelines—and if in doubt, get the tape measure out to double-check your measurements. “Maternity underwear is designed to accommodate a growing belly and, in many cases, is more comfortable than regular underwear,” says Wider.
