We tried Amazon’s bestselling one-piece swimsuits — see which impressed us most

Have you ever seen a tummy-control swimsuit this chic? Not only is there ruching along the sides to create a slimming effect, a criss-cross neckline and sexy cutout give it a fashion-forward feel. Our Senior Health Commerce Writer, Laura Williams tested it out and loved how comfortable it was and said she appreciated how easy it was to move around in. Despite its sultry cut-out and open back, she said it was "a great suit for water activities." Though maybe not for intense water sports, but for a casual active day, she found it perfect.

Williams said the suit supported her bust nicely, which was a bonus since she is still nursing a 1-year-old, and she liked that the back of the suit stayed put and provided ample coverage. "I have a bigger bottom, and prefer more coverage and this suit delivered," she said. Though she did note that she wished the suit offered a bit more lift in the backside. The one-piece ranges in size from XS to 22 Plus and it comes in 32 colors and patterns, which is great since Williams said it’s so stylish you may want more than one in your summer rotation.

Over 24,000 shoppers are five-star fans, and our Gift Editor, Amanda Garrity and Deals Writer, Britt Ross are among them. This ruffled silhouette will look great on all shapes and sizes thanks to the flattering ruching on the tummy area and the lace-up ties at the back that Garrity said allow you to find a comfortable fit. Ross noted that the front is quite low-cut, so if you prefer more coverage this isn’t the suit for you. But she loved the medium coverage the bottom provided. "it wasn't riding up my butt, but also didn't make me feel frumpy," she said

While Garrity loved the ruffles, Ross found them a tad too big as a very petite person but still found the suit to be super cute and flattering. Neither had issues with the suit becoming uncomfortable or see-through when wet. And they found it perfect for lounging at the beach or pool or partaking in low-impact water activities. But both did note, due to the low neckline they wouldn’t wear it for more intense activities.

This sleek, classic maillot by Cupshe features a V-neck, high-cut sides and ruching that smooths out your midsection. Our Home Editor, Lisa Schweitzer said "There was less bottom coverage than I assumed there would be, but it was actually flattering." She also felt supported in the bust, even though the one-piece doesn’t have built-in cups or thick straps. Ross agreed saying "When I first put it on, I was worried that it was too low-cut and that my boobs looked floppy. But once I adjusted the straps, it gave me the lift I was looking for and raised the cut. The bottom was just right for me — medium coverage with a high-cut leg that gave my 5' tall self a more elongated appearance."

Both found the ruched midsection to be complimentary and said it gave a sort of camouflage effect, but they didn’t notice much tummy control otherwise. Overall they said if you’re looking for a simple yet chic silhouette this is a great choice. "It doesn't have a lot of bells and whistles, but I prefer a more minimalist suit. I really like the classic silhouette and the lower-cut chest area, though it's certainly not a plunging neckline. (The Amazon photo seems exaggerated.)," said Ross.

Its modest silhouette, scoop neck and side-tie knot skirt are just a few of the reasons why this suit has racked up a near-perfect rating on Amazon. And our Senior Operations Analyst, Amanda Rickert and Deals Writer, Carrie McCabe are both fans of the curve-hugging swimdress, though they did wish it was a bit more supportive overall. "Coverage is pretty good. I was more interested in covering the upper thighs and backside area so I didn't wear it tied up at the bottom; I do wish it was a little longer, it does feel a little short for a typical swimdress. But I'm fairly bootylicious, so those who are a little smaller might not have that problem," said McCabe.

Rickert noted that while the suit felt snug in the midsection, it didn't feel like there was active control. "There is no fabric bunching that appears to be doing anything, so no illusion either," she said. The extra coverage the skirt provides gave her more reassurance to take part in water activities without feeling exposed. She did note that while part of the back is sheer when wet, the front is lined and the skirt around the bottom prevents you from showing off anything you don’t want to be seen.

I tested out this Cupshe suit and loved the modern feel of this square-neck one-piece and that the strappy back gave it a fashion-forward twist. The ruching in the midsection gives a flattering effect, but I did wish it had more compression to suck me in. I found the swimsuit to be very comfortable overall when wet and dry and the straps were easy to adjust to find my ideal fit.

Garrity has also been testing the sleek swimsuit and she loved that the straight neckline meant no cleavage spilling out. However, both of us found that the lining from the inside of the suit sometimes folded over the top, which was kind of annoying to have to adjust. Other than that the suit stayed in place and both of us said we would feel comfortable wearing it during any water activity without worrying about feeling exposed. We also thought the simple design of the bathing suit makes it a great layering piece to wear under shorts or a skirt too, so you can easily go from the beach to the bar.

This suit claims to have all the coverage you want, plus mesh paneling for a touch of sex appeal, though when put to our tests the suit fell quite short. While our Commerce Editor, Janelle Randazza said the suit "held up my B-cup girls well" our Executive Editor, Nicole Sforza noted that the mesh parts fell in odd places and caused underboob to show. Neither found it comfortable enough to partake in water sports, with Sforza saying "It's more for laying on a lounge chair."

The backside of the suit in particular was an issue for Randazza. "The thighs are slit so low that the butt I've been working on all winter with squats and bike rides looks 2 inches lower and 5 inches wider. Plus, I don't have particularly long legs. It made me look like I had stumps," she said. Overall, we would probably suggest skipping this bathing suit as there were much more flattering and comfortable options on the list.

This sophisticated halter-top one-piece from Suuksess features a sexy plunging neckline, removable cups and flattering ruching on the front. "This was surprisingly comfortable, given the plunging neckline! I didn't feel like it shifted around; fit like a glove and the material felt smooth and thick enough to provide coverage," said Sforza who opted for the bright red option. She said she got several compliments when wearing the suit which she paired with a sarong. "The suit showed off the girls, if you will, but I never felt afraid that I'd slip out. It pushed them up nicely, just as advertised. I was surprised how nice it was. The bottom coverage was fine — a tad cheeky, but in a good way," she said.

Rickert also tested the suit and said while she was comfortable with the cut of the bottom, she did want to note that "at least half your cheek is always going to be exposed (especially noticeable if your butt is bottom heavy!)" She said the halter was supportive enough at the bust for light activities but mentioned she wished there was more tummy control built in. "It says tummy control on the listing but it's not doing any active tummy control for me (the feel is hugging but not flattening or redistributing anything) — most of the tummy control is more illusion from the ruching and the suit being black, I think in any other color there wouldn't be much of an effect." She also mentioned the way the top of the one-piece is designed it made her look a bit bulky in the sides, but overall she found it pretty figure-flattering otherwise.

The one-shoulder silhouette lends a sophisticated touch while the cut-out adds a hint of sex appeal. Despite only having one strap, Randazza said it was very easy to move around in without it exposing you — it was even diving board-proof! "The coverage was just enough so that I could still run around like a 4th grader on field day. I love to body surf and dive and this suit totally held up and kept me covered," she said. While there is slimming ruching around the tummy, Randazza didn’t really feel much compression or added tummy control. "My husband didn't love the ruching, but I like having a bathing suit I can gorge myself on nachos in and not show a surprise belly bulge," she added.

Schweitzer found the black version to be very figure-flattering, but the material wasn’t as soft or as smooth as she had anticipated. "It's sophisticated and has the look of a much more expensive suit from the front, but the straps in the back are not as sleek," she said. Overall she liked that it provided good coverage and support without pinching or constricting her but she said the sizing seemed to run a bit small.

This is the second swimdress on the list that McCabe tried; she gave this option a slight edge over the Eomenie style because she found the neckline to be more flattering for a bigger bust. The backside of the suit rode up at times but the skirt portion kept everything covered. However, she did note she wished it was "A little longer in the back — even a 'mullet' type cut would be beneficial." Commerce managing editor, Katelyn Mullen found the back coverage to be great but "The bust coverage, [was] a little less than perfect."

"I am pear-shaped, with a larger bottom and a pretty small chest. In order to wear swimsuits comfortably on my bottom, they are often too big on top. Though these straps were comfortably adjustable and making them snug didn't hurt my shoulders, the cups in the bra section were not removable, therefore they had quite a bit of space between the fabric and my body," Mullen noted. Otherwise, she found it very comfortable. "I wore it for a full day at the pool, chasing my two small kids around, and I was not fidgeting or fixing it," she said. She also loved that it dried very quickly for a swimdress and she got a ton of compliments on it. "I had four different women at my community pool stop me to tell me they liked my swimsuit and ask where I got it from," she said.

Sforza said this sleek halter one-piece "hugs my curves in a good way." Her bust felt supported even though she would consider this low neckline fairly "sexy" and she was able to move freely without showing too much. Williams said after trying it, she loved the bust coverage and the high-cut leg but wished there was more coverage in the butt. But she found the swimsuit comfortable overall and said it didn’t pinch or constrict her.

Both ladies loved how sleek and stylish the halter neck design was but both wished they chose a different color/pattern than the one they bought. Williams ordered the dark blue but would have loved a bright teal or an orange or yellow hue for summer. Whereas Sforza said "I made the mistake of buying this in LEOPARD — that was my husband's call — but I felt like a Real Housewife in it. I think this suit is better in a solid color."
