Over 20,000 shoppers are fans of this sleek, classic maillot by Cupshe. Simple but chic, it features a V-neck, high-cut sides and ruching that smooths out your midsection. Customers rave about how comfortable and flattering it is, with many saying they bought it in multiple colors because it fits so nicely. 

"This is the most flattering swimsuit!" wrote one customer. "I've had two babies and the tummy control definitely helps disguise the mom tum. I've bought this in three colors now."

This sleek halter top features a sexy plunging neckline, removable cups and flattering ruching on the front. Oh, and it comes in 32 different styles!

One 55-year-old shopper raved, "This suit is amazingly comfortable and incredibly flattering. It gives me some waist definition, doesn't crawl up my behind, and the leg openings aren't too low cut, like granny suits. My shoulders look defined from the halter tie, and my boobs look great and supported. The line across the back doesn't squish my back fat up and out. This may be the best bathing suit ever made."

This suit's one-shoulder silhouette lends a sophisticated touch, while the cut-out adds a hint of sex appeal. The shoulder strap is fully adjustable. Shoppers say the stretchy swimsuit is super-comfortable and the ruching on the tummy makes it incredibly flattering.

One customer called it the "best swimsuit" they've ever had, before adding, "I am not over exaggerating, I am 40 years old and don’t have the body that I used to have, but still want to look cute in a swimsuit … The ruching on the side sort of hides my trouble tummy area without accentuating it."

Made from a stretchy, ultra-comfortable material that will hug your curves in all the right places, this one-piece comes with removable pads and adjustable straps, so you can customize it for a flattering fit. The ruching is slimming, and the suit has lightweight compression that helps create a smooth silhouette. 

"Such a flattering swimsuit. The tummy control is very comfortable and isn’t too constricting," raved one customer.

A vintage silhouette, halter top and ruching are just a few of the reasons why this suit has racked up a near-perfect rating at Amazon. This curve-hugging suit comes in 45 colors and patterns in sizes up to 5XL. 

"The retro suit is all I could hope for. Tummy control, cups for the girls, and the pink color to die for, not to mention the exact fit. You may not be Marylin Monroe, but you'll feel like her in this swimsuit," shared one thrilled shopper.

This slimming swimsuit has over 18,000 five-star reviews from satisfied shoppers who praise its figure-flattering details and tummy-control capabilities. Optical trickery makes every single body look its best. With strategically placed sheer mesh stripes and a design that shows off shoulders and collarbones, it deserves a place in your swim rotation. 

"I love this bathing suit so much! I want it in every color. It's flattering and has good tummy control along with support," wrote one shopper.

This ruffled silhouette will look great on all shapes and sizes. The ruching around the tummy is super-flattering, while the lace-up ties at the back allow you to find a comfortable fit. There are 25 colors and prints to choose from. No wonder over 24,000 shoppers are five-star fans. 

"This is a great mom bathing suit!" wrote one. "There's enough coverage to feel comfortable at the neighborhood pool but it is still stylish and sexy. You can definitely get down and play with your kids."

$38 at Amazon

Featuring a '90s-style square neckline and padded bust, this sleek suit comes in 24 colors and patterns, and more than 12,000 five-star reviews back it up. Shoppers love that the adjustable straps help them find a comfortable fit and say the ruched shaping panel creates a slimming effect. 

"I have this same suit in this brand in multiple sizes and colors," said one shopper. "It's so flattering for situations where a two-piece or low neckline are not appropriate or desired. The tummy panel really hides lower belly pooch and the neckline is flattering but is definitely something you're not uncomfortable wearing with your family. The backside is full coverage and gives a nice shape."

$33 at Amazon

This top-rated one-piece has over 25,000 five-star reviews. You'll get all the coverage you want, plus mesh paneling and careful gathering for a bit of sex appeal. It comes in 44 colors and patterns in regular and plus sizes.

One customer raved, "This swimsuit is a game-changer for anyone looking to feel confident and stylish at the pool or beach. The high neck design provides excellent coverage and support, while the plunging neckline adds a touch of allure without feeling overexposed. The ruched detailing not only enhances the overall aesthetic but also provides tummy control."
