6 Best Plus Size Maternity Underwear Options

Below are the best options for plus size maternity underwear and reviews from plus size parents. If you're looking for maternity clothing – we've got you covered with our plus size maternity clothes guide.

1. Plus Size Maternity Underwear Over The Belly

When it comes to plus size maternity undergarments – these are the ones that come to mind first for most people.

Plus size maternity briefs provide great comfort and support. We feel like every panty drawer needs at least a few of these, and this option goes to 4XL!

Do not worry if you need a larger option – we have you covered throughout this resource.

2. Plus Size Maternity Support Underwear

All basic plus size full coverage maternity panties provide some level of support, but this plus size maternity underwear over the belly option goes to the next level!

Plus size belly support underwear is made from different materials like spandex. You not only get full belly coverage but these can also help smooth out your belly if it’s shaped like a B and you’d like a smoother shape.

3. Plus Size Boy Shorts Underwear

From your plus size pregnancy well into postpartum, plus size boy short underwear is a great pick! Yes, there are maternity-specific options but you don’t have to pay extra for that maternity label. The design of these undies should last from pregnancy to motherhood.

Speaking of design, boy shorts not only come in many patterns and colors but also can be frilly with lace – plus size maternity intimates! There’s truly a style for every preference from the cotton boy short underwear that goes to 6XL to lace options to 5XL. Both have hundreds of positive reviews!

You might also like these Fruit Of The Loom boxers that go to 6XL.

If your panty preference is a thong, just size-up for plus size thongs! You can do the same with plus size lingerie – just size-up or select baby doll designs with a slit opening for your growing belly.

4. Plus Size Maternity Under Belly Panties

If you're unsure if you want plus size maternity underwear that goes over or under your belly, you'll love this fold-over option! With this design, you can pull it up over your belly for extra support or fold below your bump if that's more comfortable.

These undies are super comfortable, but might not be the best fit if you have an apron belly.

With different colors and sizes up to 3x, you'll want to check out these briefs!

No one really wants to talk about it, but preparing for postpartum bleeding is an important part of getting ready to have a baby. Your postpartum recovery process will include a few days to a few weeks of bleeding so it's good to know about disposable maternity underwear plus-size options.

Will the mesh underwear hospitals provide for labor and postpartum fit me if I’m plus size?

The answer is that these mesh undies aren’t one-size-fits-all, they actually come in different sizes! Be sure to ask your care provider about what your selected medical facility offers. You can also purchase your own mesh underwear that goes up to a 3XL.

“Whatever you do just buy some big ones to that you don’t mind tossing out (if need be) for the month after.” – Sarah

6. Plus Size Underwear & Other Options

We’ve mentioned this a few times already but good old regular plus size underwear, whatever your preferred style, can last throughout your pregnancy. Just size-up!

One of the most popular options for those who like the full brief coverage is Fruit Of The Loom Flexible Fit that goes up to a size 6XL. 

“I just wore my regular underwear but a size bigger!” – Brandi

“Grannies all the way! Just My Size brand is great!” – Krista

Another option might make you chuckle but it’s a suggestion many plus size moms-to-be share: wear your regular underwear backward!

“Wear them backward” – Tinika

Boxer briefs are another solution people have found if their partner wears them. The benefit of boxer briefs is that not only do they work as maternity underwear, they also offer some belly support and prevent inner thigh chafing.

“My hub’s boxers! LOL” – Jessica

Last but not least, just go commando!

“Umm…. I wore none.” – Ashley

Where To Buy Plus Size Maternity Underwear & Regular Plus Size Underwear

While there are options beyond this shortlist, below you’ll see the most popular places to purchase plus size underwear (maternity or regular).

1. Motherhood Maternity

Motherhood Maternity is the go-to for all things plus size maternity. What a lot of people don’t know is that you can purchase Motherhood Maternity underwear and maternity clothes options on Amazon!

2. Walmart and Target

Walmart! The plus size maternity underwear Walmart selection is limited. That said, their regular plus size underwear sizes are a popular option during maternity. People just size-up! Target is an option too but their sizes run smaller.

“Walmart has a small maternity section. They have these super comfy over belly 2-packs. I still wear mine!!!” – Jerrica

3. Belevation

Another popular plus size maternity brand is Belevation because of their plus size underwear support design.

“Belevation are soooo comfy!” – Alexandra

4. Torrid and Lane Bryant

Torrid and Lane Bryant are leaders when it comes to plus size clothing. For plus size maternity undies, sizing up regular underwear is a suggestion you’ve read about. While many people don’t want to spend $15+ for 1 pair of underwear, both of these stores often have sales and great clearance selections.

5. Kindred Bravely

Kindred Bravely might work if you’re on the smaller size of the plus size spectrum (18/20). The quality of their clothes is superb but they aren’t by definition a plus size clothing brand.

6. Amazon

Amazon is the leading online shopping resource and there are far more plus size maternity options that can be found via Amazon than anywhere else!

From briefs to thongs, now you have a lot of great options when it comes to finding your perfect pair of plus size maternity underwear! Feel free to share in the comments below anything that worked well for you.

The idea of just sizing up on your regular underwear is just not an option for me. They don't make anything over 13 and thats my size! Wearing them backwards is ridiculous because I have a huve but and I am not interested in weggies thanks. In none of your links did I find anything past size 13 or a 3xl. Super frustrating because I thouvht I found the answer.

@plussizebirth, tomboyx carries underwear up to a size 6X


Saturday 14th of August 2021

Hi Ginny, I sure feel your frustration. If plus size maternity underwear options existed beyond a 3X - they would be listed. If you happen upon anything, please let me know. I've spent so many hours searching. That's why I create this resource with other plus size underwear options based on feedback from plus size people during pregnancy. Have you tried the boy shorts style? That worked well for me during pregnancy and there are options to 6XL listed. I'm happy to search for you if you need larger. Best wishes!

I'm 55 and have this same problem belly apron, not due to pregnancy have lost weight just getting worse the rashing is beyond awful with an atrocious order feels like if I can smell so can others. Cleaning numerous times daily gold bond worked for a bit but was so messy that started using towel with it. Suited two purposes to help keep dry & powder in place. Then i discovered no stain stick deodorant area must be dry super dry before using or makes it messy and just not worth doing, promise it works but problem now is night sweats and small case of bci bladder control issue mainly at night so trouble finding something to wear at night. Thinking of trying the old hospital pads that use a belt with to see if might help at night. Will follow with update. Thanks for those of use with this issue not from pregnancy most sites say exercise exercise unable due to lung disease.
