Best Maternity Underwear

The short answer

Over-bump or under-bump

Over-bump

A full panel coming up over the bump. More support, smoother line under clothes, and nothing to slide. The complaints are heat — it is another layer across your abdomen all day — and the top edge rolling once the bump pushes against it.

It is also the rise that matters later: after a caesarean, a waistband sitting on the incision is painful, and a high rise clears it entirely.

Under-bump

A wide band sitting beneath the bump. Cooler, invisible under fitted clothes, and preferred by a lot of people through summer. Its failure mode is gravity: once the bump has real weight, the band works its way down over a few hours.

Foldable

The underrated third option. A fold-over waistband means the same pair is over-bump when you want support and under-bump when you want to be cool, which is genuinely useful across a pregnancy that spans two seasons.

Fabric: why cotton is worth seeking out

Stretched skin itches. It is one of the more commonly reported discomforts as the bump grows, and ACOG's material on skin conditions in pregnancy covers the broader territory. Synthetic fabric against itchy, stretched skin makes it worse; cotton does not.

Add to that the fact that pregnancy makes you run warmer and sweat more, and cotton or a cotton-rich blend becomes a sensible default rather than a preference. The trade is that cotton loses shape through a day and needs washing to recover.

Seamless synthetic has its place, which is under fitted clothes where a cotton waistband would print through.

How many do you need?

More than for ordinary life, for three reasons: you will be washing more often, you may have more discharge (which is normal in pregnancy), and later on bending to sort laundry is less appealing.

Eight to ten pairs is a comfortable number. A mixed pack of six plus a couple of better-made pairs covers it, and the better-made ones are what you will still be wearing afterwards.

Do not buy all of them at once in one rise. Buy a mixed pack, find out which you prefer, then top up.

The postpartum overlap

Worth planning for, because it changes what to buy now.

For the first week or two after birth you will want mesh or disposable pants rather than anything you own — they hold a maternity pad, they breathe, and you will not mind ruining them. That is a separate purchase and it is covered in postpartum underwear.

From week two onward, high-waisted maternity underwear is what most people move into, and it is the thing that keeps getting worn for months. That is the argument for buying a couple of good high-rise pairs now rather than only cheap packs: those are the ones with a second life.

How we picked

Six axes: whether it stays put, fabric comfort, breathability, size range, whether it survives washing, and cost per pair. Staying put and fabric comfort are weighted hardest, because those are what the reported complaints are about — sliding waistbands and synthetic fabric on itchy skin.

We read the current listings and the reported experience; we have not worn these. The method is on how we pick.

One thing worth mentioning to your provider

Increased discharge is normal in pregnancy. Discharge that is itchy, sore, smells unusual, or is green, gray or bloody is worth mentioning to your midwife or GP rather than assuming it is ordinary. So is any fluid that might be leaking rather than discharge, particularly before 37 weeks, which needs contacting your maternity unit now.
