The 10 best Prime Day swimsuit deals our fashion editor is grabbing — all under $50

The one-shoulder silhouette lends a sophisticated touch while the cut-out adds a hint of sex appeal. The shoulder strap is fully adjustable in the back, and the suit comes with removable bra cups. Shoppers say it's super comfortable, and the ruching on the tummy makes it incredibly flattering. 

One customer called it the "best swimsuit" they've ever had. "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."

I love a plain black swimsuit! This halter one has ruching around the bodice, so it's a bit forgiving, and a material that just sucks you in. I think it will look great with a pair of white linen pants, which I plan to wear it with when I head to the pool this summer. 

Plenty of other Amazon shoppers who've already bought it say that it's very flattering, and that they may even order another in a different color!

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 portion has a drawstring attached so you can adjust it to show off as much thigh as you like. 

"This is best swimsuit I've ever purchased," raved one five-star reviewer. "It's classy, but inviting, and covers the right areas while still saying 'HELLO!'."

Consider this criss-crossing one-piece your new poolside crush — I know it's mine. With clever tummy-control mesh panels that smooth your midsection while still showing off a hint of skin, this suit is both flattering and alluring. It also has the details that translate to comfort in a bathing suit: removable, padded push-up bra inserts, a snug and supportive fit up top and a full-coverage bottom. 

This has been on my wishlist for a while, and I'm finally taking the plunge now that it's on sale for as little as $20. Prices vary by color and size, but this sleek white option is the lowest I've found.

Get ready to sea-riously slay your beach game with this gorgeous swim dress. Over 1,000 shoppers bought this pick in the last month, likely because of its lightweight compression that helps create a smooth silhouette, coupled with the flirty, tie-knot skirt and gold details that give it a high-fashion touch. 

Another plus? I love that the skirt is adjustable, because if I'm opting for this style of suit, I want it to fit just right. I'm grabbing this sleek blue, but it comes in 18 other options, including some cool color-block styles.

Available in six pretty shades, women with a full bust will appreciate the wide straps and soft cups on this supportive top. The ruching also works wonders to disguise a pooch, and the matching bikini bottoms deliver full booty coverage. Unlike other tankinis that have a cropped top, I like that this style has a longer cut, so it gives the same amount of coverage as a one-piece, but still allows you to tan your tummy or show off a hint of skin. 

With sets as low as $17, I plan on grabbing at least two (don't judge, a fashion editor can never have too many swimsuits), so I can mix and match the tops and bottoms.

With ruching that cinches where it counts and adjustable shoulder and back hook straps, this is the figure-flattering swimsuit I've been waiting for. The cut-out under the bust keeps it from feeling matronly, while the full-coverage bottoms will give me confidence when I'm strutting my stuff at the pool.

Another bonus? As a style expert, I appreciate any piece of clothing that multitasks — it adds value! — and this is basically two suits for the price of one, thanks to the reversible bottoms. Just flip them over for a whole new vibe. And it's almost 45% off! This pick is also size-inclusive, up to 22-plus, and available in 11 styles. 

Look, as much as I like the idea of bikinis, most are way too revealing for me to feel confident in. That is, until I saw this retro-inspired cutie, which has convinced me to give a two-piece a try. The longline top offers way more coverage than most bikinis, and the sarong skirt has tummy control and a drawstring that lets you show off as much leg as you like. 

I'm obsessed with the gingham print, but there are 17 other styles to choose from, including simple solids, classic stripes and fun animal prints. Prices vary by size and style, but none are over $40.

I've had this ruffled silhouette on my shopping list since last summer, and it's finally time to take the plunge and snap it up, now that certain styles (like this gorgeous green color) are down to the lowest price of the year! The ruching around the tummy is super flattering, and I love that it has lace-up ties at the back that allow you to find a more comfortable fit. There are 25 colors and prints to choose from in sizes XS to 2XL. (No wonder over 26,000 shoppers are five-star fans.) 

I own this suit in a blush shade and love it for a few reasons. First, the square neck and strappy back make it feel more modern than your typical maillot. But my favorite detail is the ruching, which takes an already flattering suit and cranks it up to 10. It's super comfortable, both wet and dry, and the straps are easy to adjust. I also like that I can wear it with linen pants or shorts and head straight to lunch or the bar since it looks like an elevated bodysuit. I plan on scooping up this earthy brown color now that it's the lowest price I've ever seen it.

Is there a woman alive who hasn't heard of Cupshe and its massive swimwear collection? If that's you, let us introduce you to a brand that combines affordability with fashion-forward design. Take this suit: Tankinis are trending this summer, and Cupshe elevates the style with a lovely detail like shell stitching. But it's not just cute: The nylon-spandex blend gives stretch and support, while the removable cups and thick adjustable straps ensure you're supported whether you're cannonballing or paddleboarding. 

This 30%-off beauty is available in 18 colors, and one more thing about the brand: It's super size-inclusive; this pick is available in XS to 22-plus.
