Best Options for Super Plus Size Maternity Clothes

Before we dive in, we have a more extensive plus size maternity clothes resource with a list of places to shop. This resource is for the best plus size maternity must-haves with super plus sizing.  

Plus Size Maternity Underwear Options

Okay, some people like their plus size maternity underwear and there's nothing wrong with that.

I just prefer wearing plus size boy short underwear.

I like to look cute while feeling comfortable at all times! Plus I'm on a budget and boy short undies last throughout pregnancy and beyond (not to mention larger sizing options).

You'll find what works for you, but also be surprised how long your own undies last throughout your pregnancy.

Plus Size Nursing Sleep Bra

I sure recommend picking up a wrap nursing sleep bra as I shared in the video. Not only is it functional, but it's also super comfy throughout pregnancy and postpartum.

Sizing ranges from the popular Motherhood Maternity bra (fits most people who wear a size 22/24) to the comfort bra that goes to 6XL below.

Plus Size Nursing Tank

While this wasn't included in the video, we sure think a plus size nursing tank is a must-have during pregnancy and postpartum.

As your body changes during pregnancy, you'll appreciate a little extra support.

Motherhood Maternity's tank with built-in bra is a popular option, but their sizing seems to be currently very limited.

So, don't limit yourself to the “maternity” label!

Regular tanks with built-in bras that have a bit of stretch will last throughout your pregnancy. You just might need to size up. This one below goes up to size 6XL.

Plus Size Maternity Shapewear And Plus Size Maternity Support Belt

If you're feeling some back and belly aches, my boxer brief tip might not provide you with enough support. There are many different types of plus size belly bands, shapewear, and support belts.

One option many plus size women rave about is the Belevation maternity underwear go up to a size 26. There's also a basic belly band that's super popular.

See even more options here – Plus Size Belly Band Resources

Plus Size Maternity Jeans

While plus size maternity jeans are a must-have for many, they are difficult to find in larger sizing.

The go-to for plus size maternity jeans used to be Motherhood Maternity. Like most plus size maternity jeans, they go up to a size 3XL, but their selection is more and more limited.

Another option is Good American, where they say they offer jeans up to size 26 – but those are slim pickings. However, if you're a size 24 or under, they have you covered.

A workaround is to make your own plus size maternity jeans and it's not as difficult as you might think.

6. Plus Size Maxi Dresses

Go through your closet and pick out loose-fitting or maxi dresses. Hit up affordable stores, like Ross, that carry plus size maxi dresses.

You don't need to pay extra for “maternity” maxi!

Amazon has a lot of affordable plus size maxi dresses, including the one below that, goes up to a size 26 and comes in 19 different colors and patterns.  

7. Plus Size Maternity Yoga Pants

I talk about plus size gaucho pants in the video but these days the go-to seems to be plus size maternity yoga pants. But I don't think you can go wrong with either!!

Comfy black pants, that you can dress up or down, are a necessity during pregnancy!

Most maternity options like those Pink Blush carries goes to 3XL.

If you want a larger size you'll need to skip the maternity section. Stretch, featured below, goes up to a 5XL and will last you from pregnancy to well into motherhood.

8. Socks

This tip is something you probably won't see on most lists but it's sure on mine – fuzzy socks!

Swollen feet and pregnancy go hand-in-hand so why not treat your feet to something soft and comfy?!

But along with fuzzy socks, there are two other types of socks you might want to consider during pregnancy.

First, compression socks have many benefits during pregnancy including to help reduce the risk of blood clots (see our favorite plus size pair below).

Second, grip socks are handy for any time spent at the hospital for childbirth or if you have slick floors at home.

9. Plus Size Maternity Swimwear

This is another item that didn't come up in the video but it should've because swimming was one of my favorite things to do during pregnancy!

Swimming is a fabulous way to not only get in some great physical activity during pregnancy but also enjoy the benefit of feeling weightless.

Pick yourself up a plus size maternity bathing suit and hit the pool (look out for indoor recreational centers during cold months).

The tankini suit below goes up to a size 28 and comes in many different patterns. Tankinis are a great alternative to splurging on a maternity suit.

Once you have the essentials above, you can raid your own closet!  You'll be surprised how long you'll be able to wear your own clothes. Yet, it's also nice to treat yourself to a few cute plus size maternity tops.

I hope you found these plus size maternity clothes tips helpful and regardless of what you're wearing, your beautiful pregnancy glow is the best accessory ever!

I was lucky with my first pregnancy in 2016 in that I started at 295lbs and delivered at 330lbs and I didn't buy maternity jeans until my last 3 weeks, I found them on (I lived in them for a few months after just because they were comfy post c-s) Otherwise I lived in plus size maxi skirts from Dress Barn and Target, Yoga pants from Lane Bryant with a control top panel which helped with Belly Support, found a few loose tops at Walmart and TJ Maxx and all was well. I lost all the baby weight within 2 weeks but then came down with gallstones which required Surgery 1 month post c-s (that outpatient Surgery was worse than my c-s) When I went back to work the weight slowly crept back. Now I'm in 2018 and starting pregnancy No. 2 and everything is different! I was finally loosing weight made it to 315lbs, then the weight started to come back and I realized I was pregnant. This time I have zero energy and feel discouraged while trying to shop to buy a few items that might fit. I can't wait for December to get here and this is all over!

I'm in my second week and I think I will need to follow your tips because I'm already getting bigger. I can't seem to stop eating more and more. Pregnancy makes you hungry all the time. Anyway thanks for the useful tips.

I can't tell you how relieving it is to see this website. I am nearly 8 months now and have struggled to find anything that fits me. It's bad enough companies and clothing lines don't make plus size clothing but so many stores are taking away their maternity clothes!!! Or they have one small rack that is meant for size 2. Seriously what are pregnant women suppose to do go completely naked???? While I love the motherhood store it is sooooo expensive, I had to get super creative with my wardrobe, I wish I had been big in the summer because I could get away with the dresses but alas I am having a Christmas baby. I currently have one pair of pants that fits me that I have to wash over and over again it sucks. I ended up buying a bunch of mens long sleeve shirts at a yard sale just so I can have something for the go to times. I had a couple of belly bands but I even outgrew those but thank you for making me feel better I needed to see this.

I'm so glad my site brings you comfort, beautiful!!

You have some good suggestions, however, I believe most of them work best for someone who is an apple shape. Could you provide some suggestions that would work for other shapes, for example a pear. I am a pear shape (size16/18 top and size 24/26 bottom). I know I'm going to struggle finding pants and bottoms that fit as I've already searched on plus size maternity clothing sites and most just barely will truly fit a 26 (and they don't have any larger sizes). And I can't fall back on the maxi dress solution until I can find maternity shapewear to keep my thighs from rubbing.

Could you speak to those items? And are there any maternity stores you can suggest for anyone who is a 24 and larger?

Anthe- I am not pregnant but I am plus size and have a large tummy. Underneath dresses I wear a pair of leggings that I cut into shorts to prevent my thighs from rubbing. They have leggings in extended sizing at Walmart and on amazon. This is a great tip (and cheap) and has been a huge lifesaver for wearing skirts and dresses. Plus it’s way more comfortable than spanks.

Hi Anthe! Thanks so much for your comment. I just did a posting on the Plus Size Mommy Memoirs Facebook page for you ( I hope you get lots of helpful feedback learning how to dress for all different body types. As for size 24+ I've heard positive things about Woman Within and there's always online coupons you can use.
