Old Navy / Bare Necessities

Buying a new swimsuit is something that’s usually high on the shopping list when a vacation is on the horizon. Well, ladies, it ain’t right now…but that bb pool and sprinkler pad are looking really appealing after a long winter spent inside. And just because we’re swimming in our backyard doesn’t mean we want to wear something outdated and out of style.

In-store shopping is not ideal this year, so we’re shopping for swimsuits online exclusively. Leaving many of us wondering – “Where can I even buy cute bathing suits online?”

There are great options— many with hassle-free returns or exchanges, so you can figure out style and size preference at home. Anyone who has ever tried on a bathing suit in the fluorescent lighting of a fitting room with a toddler can appreciate the appeal of trying on a suit from the comfort of your own bedroom. (Send the kids outdoors for a swing break and start the fashion show!)

There are a few key things to think about before shopping online— even just knowing the color palette or style ahead of time can make the whole experience less painful. Also, have a good idea of what size you’ll need (size charts and reviews from other women are our best friends). Consider— get ready for this— something a little out of your normal wheelhouse. Do you really need another black or navy swimsuit? Are you ready for a bold print or maybe even a two-piece? We say YES.

We’ve done the homework and found fun, festive prints, and beautiful solids in one-pieces and bikinis, each guaranteed to give us the coverage we need and be figure-flattering— while still ensuring we can still keep up with whatever our LOs throw at us. All that’s left to do is click “add to cart”.

Based on style and ratings, these are the most trendy plus-size swimsuits of 2021!

Sovoyontee 2 Piece High Waisted Swimsuit

This two-piece reveals just enough with plunge top and the ruffled high wast bottoms. Available in 7 colors and patterns from classic olive to an American flag motif (Fourth of July, perhaps?), you’ll certainly have your pick. Reviews don’t lie and this one’s a crowd favorite, so snap it up before the temperatures turn scorching.

CUPSHE Natalia Striped Belted Plus Size One Piece Swimsuit

CUPSHE, an LA based swimwear brand (so they know what they’re talking about in the world of swim!), offers beautiful and affordable swimsuits to women of all sizes. We love this belted one piece for the stripes it offers. The v-neck with cross back means we can adjust the top to fit our exact comfort level without being completely covered up. Although our favorite feature for the plus size ladies is the cool buckled straps. Having a belt around the tummy gives the appearance of a flatter stomach, while the high cut bottom extends our legs, making it good for all body types.

One reviewer shared, “This is a great quality bathing suit. The design is unique and the fit is perfect!

Daci Tummy Control Bathing Suit

After having a baby, a ruched one-piece like this with tummy control was my savior. I will also admit that nearly 10 years later, it’s still a fave in my swimsuit wardrobe. With 16 styles to choose from, you can grab one in a fun color or print like the hot pink suit, or opt for a neutral color like navy. And for this price, why not buy two so you can pick according to your mood that day?

Swimsuits For All Lace Plunge One Piece Swimsuit

This sexy one piece might be for hot tubs with the husband rather then the kiddie pool but it still has a place in backyard fun. Or maybe we save it for a girls weekend when girls trips once again become a thing? Either way, this suit is fun and fully lined (a must have) with molded wire-free cups and a power mesh tummy control panel. Swimsuits For All is an online exclusive retailer for women sizes 4-26, so they know a thing or two about how to fit a woman in a bathing suit. The details of the banded waist and adjustable straps are figure flattering. 

One reviewer shared that the suit is, “Incredibly flattering, sexy, and comfortable. I get SO MANY compliments every time I wear this suit. I found it fit very much true to size, if not running a little large. I’m 6′ and typically wear a 14-16. After adjusting the straps a little bit, the 14 fit like a glove.”


OLD NAVY Deep V-Neck Secret-Slim Underwire Plus-Size One-Piece Swimsuit

Accentuating a women’s waist is a great feature for a trendy plus size bathing suit to have. Old Navy’s Deep V One Piece is an optical illusion of a perfectly nipped and tucked waist. Expertly designed with a pattern laid in varying ways, our waists look slim and trim. The adjustable straps and cut-out back only add to the look by creating our perfect fit. 

Looking at a swimsuit’s size chart before buying online is our number one piece of advice. These are usually found on a brands website, right next to the size button. Reading customer reviews is also really helpful, they’ll tell you what worked and what didn’t. This swimsuit works for us, and we love it in dark navy and in the bright coral option.

La Blanca Tropical Rain Over the Shoulder One-Piece Swimsuit

La Blanca has been around for more than 40 years creating beautiful, long lasting, fashion forward swimwear for women of all sizes. With the La Blanca mission of making women feel comfortable in their own skin, the Tropical Rain Over the Shoulder suit delivers. In a fun island print (hey we can pretend we’re in the Tropics right?), the off the shoulder neckline is a good option for avoiding awkward tan lines. But if you’re more than a little afraid that junior will just tug it down (we’ve all been there when they decide to just explore!), never fear the top will stay in place with the included detachable straps. Simply remove them during nap time when you get a little me time out by the pool.

Speedo One Piece Endurance+ Swimsuit

Sometimes we just want a good classic black bathing suit with tummy control. Done. Speedo’s One Piece Endurance+ Swimsuit offers powerful compression mesh tummy control support and a built-in bra all made out of long-lasting bio-based material up to size 24. It does also come in blue, purple and a pretty print if you’ve got your black one-piece already set. A pro-tip for this suit is to size up. That powerful compression panel means going up a size. We think it’s worth it since the slimming feature is so effective.

According to one reviewer, “As a heavyset woman who has needed to get back into swimming for exercise but has dreaded the thought of wearing a matronly, dowdy, frumpy, manish looking, “practical” swimsuit this swimsuit has spared me. It has a panel down the front that is ruched in a way that doesn’t give “too much information” and makes me feel snug and secure without feeling like a sausage or like I’m letting it all hang out. It’s sleek. It’s fashionable. It’s understated with a slight vintage quality. It’s sturdy. If you’re looking for a bathing suit that you’ll feel as good as possible in, this is it.” We couldn’t have said it better ourselves!


Summersalt The Sidestroke Swimsuit

Summersalt’s best-selling Sidestroke one-piece is truly one of the most flattering swimsuits out there–just ask one of the 900+ customers who gave this suit a perfect rating score on the brand’s site. So what exactly is it about the Sidestroke that has women going wild? It could be the compression fabric that keeps everything exactly where it’s supposed to be, providing support for all bust sizes without cups or pads. Or perhaps it’s the full-coverage bottom–or the fact that this one-shoulder bathing suit is offered in 11 color-blocked colorways (always with the darker color strategically placed at the bottom), in sizes 0 to 24, as well as a long torso option. Most likely, it’s all of the above. As for those happy customers, they consistently rave about the quality, support, and overall look of this swimsuit. As one put it, “I have gotten so many compliments on this suit. It’s very flattering. I haven’t had a suit look this cute since before my kids.” And there you have it.


Best Plus Size Tankinis

B2prity Tankini Set

As an option for plus size swimwear, Amazon provides a lot of variety at affordable prices. However, it can be hard to sift through it all when you’re a busy mom. We love this 2-Piece Tankini from B2prity with an included bottom. A tankini is like a one piece, but better! You’ll know what we mean when you need a bathroom break. The looseness of the top creates a forgiving silhouette if you’re postpartum and need a little extra room. Available in 19 patterns and up to size 24 plus, there is surely something for mamas of all shapes. 

One reviewer had this to say, “I really love this bathing suit. It is cute while still providing coverage. I am a size 18 in jeans, and I ordered an 18 plus – it fits perfectly. The shorts are high-waisted and not too tight. The top provides enough support for my 44D bra size.”

Aqua Eve Women Plus Size Tankini Swimsuit

Sweet, simple, and classy. This tankini set is super comfy and supportive with the flowy bottom and removable push up bra. Take it from this Amazon reviewer who said, “LOVE is an understatement!” they raved. “Usually swimsuits that are loose enough in my belly are too big in the bust. This one is perfect. It helps to disguise my broader back w the way the back is cut and also hides armpit fat lol… This swimsuit helps me feel better about myself in a swimsuit. I recommend!”

Best Plus Size Swim Dresses

Magicsuit Plus Size Brynn Ruched Tank Swimdress

Plus size swim dresses have the ability to look oh so grandma-like if we’re not careful. Magicsuit’s Swim Dress is sexy and functional we’ll definitely be wearing it around the pool this year. The ruched side leg creates a slimmer silhouette and lengthens legs (yes please!) while the convertible straps can adjust to fit our precise needs.

A pro-tip for ordering swimsuits online is to order multiple sizes in your favorite styles (this one is available from size 16-24). Try your usual size and then one size larger so you can try them both at one time and compare the comfort and coverage. 


Old Navy Printed Secret-Slim Underwire Plus-Size Swim Dress

When looking for plus size swim dresses (or plus size swim wear in general) the patterns aren’t always the latest. Luckily, good ols Old Navy has got us covered (as usual) with this super cute black and white polka dot swim dress. It kind of looks like the trendy Dalmatian print, right? It even has underwire for extra support and cute tie detail to make it unique.

$56.99 AT OLD NAVY

Best Plus Size Two-Piece Bathing Suits

Torrid One Shoulder Flounce Bikini Top With High Waisted Bottom Swimsuit

Does summer make you long for the days before BB when you were able to rock a killer 2 piece? Us too. We love this High Waisted Bikini from Torrid to cover any scars acquired post baby and it’s cute one shoulder top. The one shoulder look of this swim top provides additional support for bending and lifting without having to worry about things coming loose, but just in case you want more, there is a detachable thin strap for the other side. 

One of the best aspects of Torrid’s website is the ability to see these suits on models of various sizes. Torrid’s suits come in sizes 00 to 6 (equivalent to size 10-30) but are shown in a 1, 2, or 4 depending on your preference to give the most realistic idea of what you might look like in the suit. With the tops and bottoms sold separately, you can get whatever size fits best in each piece, and mix and match styles for a really custom swimsuit

Old Navy Textured Underwire Plus-Size Bralette Swim Top

A bralette swim top means extra support and we’re here for it! This ‘Corazon’ red also makes it chic. Note that this cute set is sold separately, so don’t forget to grab the high waist bottoms too!

Cheap Plus Size Bathing Suits

Yomoko High Waist Bandage Bikini Set

This two-piece swim suit is another Amazon fan favorite. The unique crisscross details on both the top and bottoms give a sexy (yet subtle) peek-a-boo at what you’re working with…while still be community pool appropriate. Reviewers are in LOVE with the quality and fit. One Amazon reviewer said, “Absolutely love this suit! It’s well made, supportive, and comfortable. I carry most of my weight in my stomach and boobs, and I normally stick with black bottoms, but I’m so happy I stepped out of my comfort zone.”
