“I’m three months postpartum and was so happy with how this swimsuit fit,” raved one new mom. “It’s incredibly flattering while still being comfortable, with plenty of stretch without feeling loose or saggy. I wore it to a waterpark and felt completely secure chasing my toddler. Not too cheeky, just the right amount of coverage.”
Have you ever seen a tummy-control swimsuit this chic? Who said you can’t be svelte and stylish? Not only is there ruching along the sides to create a slimming effect, there’s a criss-cross neckline and a sexy cutout give it a fashion-forward feel. It comes in 36 colors and patterns, and sizes XS to 22 Plus. And over 13,500 five-star reviews back it up.
“I absolutely love this swimsuit,” said one five-star fan. “I’ve gotten so many compliments on it. It covers all my ‘trouble’ areas and is super flattering for a ‘mom belly’. Offers me great support up top too.”
This suit has all the coverage you want, plus mesh paneling for a touch of sex appeal. The thick shoulder straps are fully adjustable to help you find the right fit, plus the swimskirt has a drawstring so you can show off as much or as little thigh as you like.
“This is now my favorite fitting bathing suit. It’s slimming and classy. I have now purchased other colors,” wrote one happy shopper.
Nearly 23,000 shoppers are fans of this sleek, classic maillot. Simple but chic, it features a V-neck, high-cut sides and ruching that smooths out your midsection. Customers rave about the fit, with many saying they bought it in multiple colors.
“This is probably the most flattering and comfortable suit I’ve ever purchased. I came back to buy a second color. It’s got just enough ruching in the tummy area to conceal anything that troubles you,” noted this repeat buyer. “The comfort level is beyond anything I’ve ever experienced, but mostly if you have any flaws, it gives you confidence.”
This flattering swim dress is quickly zooming up the charts, with over 500 shoppers buying it this month alone. The lightweight compression helps create a smooth silhouette, while the flirty skirt and gold details give it a high-fashion touch.

This sophisticated suit features a sexy plunging neckline, removable cups and flattering ruching. The adjustable straps criss-cross in the back for extra support, and there is a tie closure so you can go as tight or as loose as you like. It also comes in over 40 styles, from sleek solids to vibrant prints.
“This suit is great! I’ve been struggling to find a good-fitting one-piece that doesn’t look weird. It’s super cute and comfortable and has great support up top. I’ve [gained] some weight recently and am super self-conscious, but this makes me feel so great about where I’m at now,” said one fan.
A 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. This curve-hugging swimdress comes in over 30 colors and patterns in sizes XS to 22 Plus.
“I’m 61, so not what I used to be body-wise, but this suit made me feel good about myself,” wrote one shopper. “The ruching was very flattering. Love the little side-tie skirt. It gives a little coverage for the top of my legs. I will more than likely be ordering another one in a different color or pattern.”
Want something a little sophisticated, with a hint of sex appeal? Here you go. The shoulder strap is fully adjustable in the back, and the suit comes with removable bra cups. Shoppers say it’s super comfortable and that the ruching on the tummy makes it incredibly flattering.
One shopper called it “the best fitting swimsuit” they own, before adding: “The fabric is stretchy and holds you in without binding or being uncomfortable. It is lightweight and breathable.”
Want to avoid pesky tan lines this summer? Try this sleek strapless one-piece. A solid-colored strapless maillot is about as timeless as it gets, and you can easily turn it into a cute top by pairing it with a skirt or some shorts. It even comes with a removable strap for when you need a little extra support.
“I love the fit and pattern of this suit! Totally recommend if you are looking for a shapely strapless number. Also, it’s slimming without being overly lined and dries quickly. All-around great,” gushed one super fan.
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 27 colors and prints in sizes XS to XL. No wonder over 27,000 shoppers are five-star fans.
“So soft and comfortable,” wrote one. “It’s a little cheeky, but still an appropriate cheeky for a mom of three. The deep V holds my girls in and I feel secure. The back can be tightened for a good fit and the front has good tummy control for a postpartum body. Overall, I love this bathing suit and feel great in it!”
