Old pants, over the belly pants or under the belly pants – which are best? Pregnancy and beyond pants don’t have to be…pants, here’s what you need to know.
You might be wondering whether to choose over the belly pants, under the belly pants or whether maternity underwear is even worth it. Then there’s after you give birth. Here’s our guide to the plethora of pants possibilities…
There are many different options for pants in pregnancy. Many women find their old knickers are fine as they sit underneath the belly so still fit well.
You might though find your old shapewear or control pants too restrictive to wear. And bear in mind you might start to suffer with chafing especially towards the end of your pregnancy. Tight or skimpy underwear might not be the most comfortable.
Other women swear by big knickers.
Mel, mum to Phoebe and volunteer with Redhill, Reigate and Horley NCT branch, says: “Full brief granny pants. Sexy? No. Comfortable? YES.”
Some women find that as well as their bump growing, their bum does too.
Eleanor, mum to Toby and member of Bromley NCT group, says: “I just bought supermarket multipacks of knickers in the next size up, ending up two sizes bigger at full term. They fitted under the bump and accommodated the ample backside!”
You can also get maternity knickers that have an elasticated band and sit high over your bump. These can also keep your bump warm in cold weather.
Whether it’s your old underwear or new maternity pants, just go for whatever feels best to you.

Comfy pants for after the birth
It’s worth having old pants on hand for after the birth that you don’t mind throwing away. (You’ll see what we mean.) You could also do this for for the end of pregnancy when your waters might break or you might have a show – the mucus plug coming away.
Some people even get disposable knickers so they don’t have to scrub stains from their underwear.
Remember that you’ll need pants that you can use maternity pads with because of the bleeding (lochia) you’ll get after birth. This bleeding can last for several weeks.
Underwear for after caesareans
Loose styles of pants are a good idea as you may be feeling sore after the birth, particularly if you had a caesarean (NHS, 2016). Big, high-waisted briefs are the way to go after caesareans as bikini styles could rub on your scar.
Women who’ve had a caesarean are particularly encouraged to wear cotton underwear (NICE, 2011). You can also buy specific post-caesarean underwear if you like.
Feeling good and looking good
Maternity underwear has moved on from what it used to be, thankfully, so you can still feel attractive.
You’ll probably have a lot of physical changes happening, which might include weight gain and stretch marks. So if investing in some pretty maternity underwear helps you to feel good about yourself and your changing shape, then go for it.
Plenty of retailers now offer lots of stylish maternity options with patterns and lace, and many come with matching bras. See our article about finding pregnancy and feeding bras.
And breathe out…
Cotton and other natural fabrics are usually the best materials to go for when you’re pregnant or after you give birth (Public Health England and NHS England, 2018). That’s because they’re breathable.
See our article for more tips on how to keep cool when you’re pregnant.
Whatever type of pants you choose, whether you go for the biggest knickers you can find, style or something in between, comfort can help you feel better. Sometimes it’s the little (or not so little) things that help you through the discomforts of pregnancy.
