May 18, 2020 Updated June 11, 2021

Swimsuits for Women

This coming swim season, we want to be ready with the most flattering one-piece swimsuits out there (we have been stuck inside wearing yoga pants for a year, after all). This time around there will still be plenty of fun in the sun—and in the pool—to be had, and that means now is the time to start searching out the most flattering swimsuits to wear this summer. We know it can be tricky finding a bathing suit that feels comfy, looks cute, and fits securely enough to allow you to focus on mom duties: That’s why we’ve taken it upon ourselves to help out.

When you’re a mom, bathing suit shopping isn’t just about hunting down the most flattering swimsuit for your bod (or about finding the cheapest swimsuit). Whether you have a baby on your hip, are bent over/chasing a toddler, or diving into the pool with your big kids, having a suit that’s supportive and stays put is just as important as style—perhaps even more so.

But that doesn’t mean you can’t have it all when it comes to a swimsuit: There are plenty of options available that meld fashion, function, and figure flattery. Matronly “mom bathing suits?” Not here. We scoured the internet—you might say we did a “deep dive”— to come up with the best, most flattering swimsuits for every mama whether she needs rashguard swim or plus size. From a chic one-shoulder suit that looks good on everyone to a bikini that’s perfect for big boobs, there’s a swim style (or several) to suit you.

Best One-Piece Swimsuit

Hilor Women's One Piece Swimwear

Hilor offers some of the most supportive–and most flattering–swimsuits for women with big boobs. Case in point: This best selling one-piece is offered in sizes 4 through 16. It comes with elastic shoulder straps with a cross-over design for extra boob support, and is totally wire free with removable bra cups to ensure it fits you just right. “Awesome suit for big busted girls,” said one Amazon reviewer. “I was pleasantly surprise that there was see through mesh between the black lines. I have large breasts between a d/dd and was worried they would either be spilling out on top of underneath especially seeing as there was no wire for support. Boy was I wrong it fits great and looks great.”

SummerSalt The Perfect Wrap One-Piece

This best selling swimsuit is known to be “universally flattering.” From the painted floral print and plunge to the the customizable knot, this personality-filled one-piece is ready for a day at the beach or lounging by the pool. (If for some reason, you don’t like the floral pattern, it also comes in a solid colors, gingham, or color block styles). We love that it provides full-coverage for your bum, so there’s no worry about overexposure and having to tug at it constantly. It shows off cleavage but it’s still modest enough for the kiddie pool. Simply put, “So incredibly flattering!” said one reviewer. “This one did not disappoint. The deep v, faux side wrap with tie, and compression is a dream. I almost stopped my pre beach vacay diet it looked so good.”


Tempt Me One Piece Swimsuit

What’s more flattering than 1) black 2) ruching 3) a high neck? Nothing, that’s what. This suit has a nearly perfect 5-star rating on Amazon for a reason — it’s sexy as hell. Better yet, it comes in a wide variety of sizes from extra small to plus size 22. And if black isn’t really your thing, this bathing suit also comes in a whopping 41 other colors and pattern schemes.


CUPSHE Women's One Piece Swimsuit Wrap Color Block Tie Side Bathing Suit

This bathing suit ties in the front, has a sleek plunge, and comes in the cutest patterns and colors! (13, to be exact.) It’s a super clever one-piece that gives off a two-piece vibe, thanks to different colors and prints on each half — and if you really want to go wild, grab one that has patterns on top and bottom!

$32.99 AT AMAZON

CUPSHE Vintage Lace Bikini

Proof that you don’t need to spend over $30 on a designer-looking swimsuit! Don’t be fooled by this adorably lacy one-piece’s extremely reasonable price tag (it looks like something you’d get at Anthropology, doesn’t it?). Reviewers are obsessed with the flattering fit, and its quality and support make it look and feel much more expensive than it is. It comes in nine colors and patterns and a few different styles, including some with side cutouts.

Best Slimming Swimsuit

Miraclesuit Network Jena One Piece Slimming Swimsuit

If there’s ever a time in our lives when we want to feel just a little bit trimmer, it’s while we’re in our swimsuits. While not nearly as bad as the actual in-dressing-room try-on experience, wearing a suit can leave you feeling a little reminiscent of your pre-kids body. Well, Miraclesuit shapes you and drapes you just where you need, and the Network Jena style does it with mesh inserts and flattering jewel tone colors. The luxurious fabric feels good (not sucked in) so you can wear this lounging on the kids sprinkle-donut floatie now, and definitely again later when you and the girls finally escape to the spa weekend planned for post #quarantine season.


Best Swimsuit for Big Boobs

L.L.Bean Women's Slimming Swimwear

Work it, mama! If this cobalt vines swimsuit doesn’t make you feel like a HMIC (Head Mom in Charge), then we don’t know what will. Seriously ladies! That tummy control lining is the definition of flattering. From the plunge neckline and ruched fabric around the tummy to the body-sculpting lining, what’s there not to love?? Plus, you won’t have to worry about showing off too much skin or pulling and tugging to keep everything in place. There’s even thicker straps in place in case you want to do a backward dive into the swimming pool. For a designated beach day, just add a sunhat and a beach cover-up (although this suit has built in UPF 50+ protection too).

Best Rash Guard One-Piece Swimsuit

AXESEA  Long Sleeve Rash Guard One Piece Swimsuit

We don’t know who needs to hear this but don’t forget to lather on the SPF. If you burn to a crisp after only a few minutes out in the sun, then a trusty rash guard will be your BFF. It’s not too late to snatch up this insanely cute floral print rash guard swimsuit from AXESEA. Picture this: You, a designated pool day, and this moisture-wicking suit front and center. Bid adieu to summer in style… and without breaking the bank. 😉 We love that this mom-approved rash guard is made from a quick-dry fabric—beyond the pool, you’ll be able to run errands in it, make an appearance at a socially distanced BBQ, or play mini golf.

Best Reversible Swimsuit

Cupshe Light Up The Night Print One-Piece Swimsuit

We pretty much live by the shopping adage of “If you love it, get it in multiple colors,” and with a reversible swimsuit, you can literally do exactly that–without having to buy multiple items. This stylish one-piece bathing suit does double duty with a dark navy bohemian print on one side and a white/blue floral on the reverse. It offers an adjustable fit thanks to the lace-up tie back, which is ideal for those who are smaller up top, though reviewers note that it offers decent support for bigger busts, as well (with pads for coverage and shaping). “This bathing suit is amaaaazing,” wrote one reviewer, “So much cuter than I even thought it would be. The material is nice and comfy as well. Very much true to size and I am thinking about getting another one because I love mine so much!” There are few things we enjoy more than getting major bang for our buck and at under $30, well, this pick delivers.


Best Swimsuit Back

Boden Lindos Swimsuit

Why choose between coverage and cuteness when you can have both? This Boden one piece swimsuit gives you coverage with a hint of sexy (just look at that plunge) and full back (no wedgie) while delivering on a really stylish crossover back. We love the simple yet bold color red, but you’ve got options between black, teal, and a fun green print too.

$68.60 AT BODEN

Best Swimsuit During Pregnancy

Bhome Pregnancy Beachwear Swimsuit

This maternity swimsuit is a fan favorite on Amazon; it comes in over a dozen colors from rich solids to tropical floral prints so there’s something for every mama-to-be. Padded cups, adjustable shoulder straps, and ruched sides help keep preggos comfy and accommodate growing bods, and the fabric features UPF 50+ for safe sunning. Expectant reviewers have praised its comfort and coverage, including one who noted “There is good support for the ladies and great coverage all around. I went with a large and it fit perfectly. Covered my butt completely, and never felt self conscious. A must have for pregnant women at the beach!” Available in sizes S through XXL, this is a one-piece swimsuit you can rely on to stay put: As another reviewer told it,  “the suit stayed in place and didn’t roll or bunch up on me as I was bending and chasing my toddler around the pool. Would def recommend this as cute maternity suit option.”


Best Post-Partum Swimsuit

Zando Women's Slimming Tummy Control Swimdress

Calling all new moms! You shouldn’t be shy about showing off your bod at the beach, but we 100% understand if you’re not quite ready for an itty-bitty bikini yet. Instead, make a bangin’ entrance with the cutest post-partum swim dress (okay, technically it’s a two-piece) featuring slimming tummy control. We love that it’s subtly sexy—it complements the curves of your body without showing off too much skin. Says one Amazon customer, “Recently took a trip to Barbados. It’s been a while since I’ve purchased or worn a bathing suit so I was a little self-conscious. I ordered it not really expecting much but I was pleasantly surprised! I ordered a large, which is about 12-14 size. I loved the boy shorts instead of the regular bottom that typically comes with a swimsuit. This two-piece was perfect for me.”

Best Holiday Weekend Swimsuit

Boden Santorini One Piece Color-Blocked Swimsuit

Memorial Day, 4th of July and Labor Day are all on the horizon, so let’s celebrate with a new (color appropriate) suit. As if we need an excuse for something so flattering and colorful. This is a one piece swimsuit that let’s you chase the kids, do a deep-dive and even get a teeny tan during nap time (let down that halter tie). And although the red, white and blue color combo is bold and beautiful, we may need a second one in the way of the berry or yellow color-block. The targeted waist definition and darker color placement down the sides is a slimming trick we all need now. Whether you’re a size 2-22, in regular torso or long, get ready to look V cute by the pool stat.

Best Stay-Put Swimsuit

Athleta Cross Train One Piece Swimsuit

A flattering swimsuit that’s stylish and stays put? Yep, it can be done–and Athleta’s done it. If you’re an active mama who doesn’t want to worry about flashing your boobs or having your butt cheeks spill out when you’re chasing the kids in your bathing suit, this brand offers sporty styles with plenty of coverage. Their high-neck one-piece gives  support in all the right places and has a perfect rating online. As per one reviewer, “This suit holds everything in the right places and even makes my bust look smaller, which I love! It’s also great because I actively swim with my 5 yr old during his swim lessons and everything stays put and I don’t have to worry if anything is “hanging out” when I get out of the pool. The quality of this suit is also superior and I feel this will last a long time.”


Best One-Shoulder Swimsuit

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 Under $50 Swimsuit

Swimsuits For All Ashley Graham Hotshot One Piece Swimsuit

For some of the most flattering swimsuits out there that won’t offend your wallet, just head on over to Walmart (online, of course). Among the selection, you’ll find gems like this chic polka dot one-piece from Ashley Graham’s collection that’s as on trend as it is affordable. From the playful print to the classic tank shape, this bathing suit hits all the right style notes–without sacrificing function for fashion. Soft, removable bra cups offer shape and modesty, and wide straps give full support up top. Available in sizes 4 through 24, it’s easy to see why this suit is an instant classic with customers–some even mention wearing it as a bodysuit, too. As one happy shopper bluntly put it, “This suit is simple but very cute. Nothing bad to say about it so far.” Another wrote, “I have tried endlessly to find suits that flatter and at 34 years old have FINALLY found one I love! Can’t wait until the warm weather to hit the pool with my little girl!” 


Best Minimalist Swimsuit

Lively The One Piece - Colorblock Swimsuit

Come for the chic styling, stay for the figure flattery! Lively’s color-blocked black one piece swimsuit is thoughtfully designed to look modern and sexy, featuring a cutout back, high-cut leg, and minimalist-friendly hues. It’s one of the most flattering swimsuits for women who are looking to draw the eye up and away from the tummy area, whether you’re post-baby or post-bagel (Do you, girl). Either way, the reviews section is filled with comments from women who say this style has renewed their confidence–that includes one that noted, “I love this suit so much! I’m 6 months postpartum and feel confident and comfortable, without sacrificing style.” Another wrote, “Bought to hide my stomach…I have a 7 month old. Super flattering. Very supportive.” The overall verdict on this swimsuit: Flattering and mom-friendly without being matronly. Or as one reviewer put it, “Every time I wear this I get compliments. I am a mom, but this is cooler than a mom bathing suit.” Done and done.

Don’t sleep on it, ladies… this suit is currently on sale for less than $200! It’s time to get ready for the beach getaway you’ve got booked with the girls.
