The good news is that you don’t have to spend tons of money to get a stylish bathing suit that also flatters your body, as there are many brands that offer options for less than $100. (Just check out some of Amazon's top-rated swim styles!)

A favorite of Senior Commerce Editor Stephanie Maida, this under-$50 one-piece from Cupshe also has my attention for its retro design and hourglass-shaping silhouette. “Not only does the (lined) fabric offer excellent suck-in support throughout, but it's designed with a crinkly texture and vertical ribbing that works wonders to elongate the figure (a boon for petites like me) and to hide any lumps and bumps,” writes Maida in her review. “The square neck is super flattering for my larger bust—sexy but not too revealing,” she adds, noting that the curved seams on the sides assist with flattering your figure. The fabric is also high-end looking and super comfortable, meaning you really get a lot of bang for your buck, considering the price.

One reviewer says it best: “I buy a new suit from J. Crew each year, and this year this was the winner. I never like how my back looks in a swimsuit, but the sculpt material of this is magic. I didn’t size up, so it’s a little tight in the chest, but buying true to size is what gave me the right amount of compression for the suit to look good. It’s also still very comfortable after you get it on. The most confident I’ve felt in a suit in years.” While, you still may want to size up if you want a looser fit in the bust region, it sounds like you can't go wrong with this one-piece with detachable straps, which is marked down in a number of colors and prints.

LSpace’s swimwear is hugely popular (for good reason!), which is exactly why this bikini top is currently a best seller at Revolve. This style is unpadded and features a triangular, halter design with a pretty crochet trim. I love the fact that it has tie straps at the neck and back, which allow you to fully adjust the fit or customize the way you style it. Want to complete the look? Nab the matching bikini bottoms, also under $100.

Snagging both a bikini top and bottoms for less than $100 is *almost* too good to be true, so I would definitely consider adding this combo to your cart, stat. The adjustable two-piece offers plenty of coverage at your bust and bum, while still giving you that sexy string bikini look. “This top is great quality, and I’ve been buying it in several colors for years,” raves one dedicated fan of the suit. “You can’t go wrong with it!”

This popular swimsuit is incredibly flattering thanks to its strategic color-blocking, diagonal seams, compressed feel and ample boob and bum support. The one-shoulder design instantly draws attention, as does the open, strappy back. But worry not—your booty won't be left too exposed. Furthermore, I like that the material is made using 78 percent recycled polyamide for an eco-friendly twist. And did I mention it comes in sizes specifically made for long torsos?

Senior Editor Abby Hepworth personally endorses this Dream keyhole bikini from Cupshe, referring to it as the "one she reaches for more often than others." "The top has a nice, wide band that doesn’t dig in, and the cups provide ample coverage without feeling dowdy,” she writes in her review. “The wide, criss-cross waist is incredibly flattering and actually moves with my body rather than digging in or pinching as I swim, lounge or walk along the beach. The leg holes are also cut to just the right height so I feel foxy but not overly exposed.” Aside from its comfort and great fit, it’s also super affordable at just $26 (yep, for both pieces).

Hepworth also recommends scooping up these bottoms from Left on Friday. “It's true, Left On Friday has developed something of a cult following thanks to its impeccable fit,” she explains, adding that this high-waist bikini bottom offers medium coverage in the back that is guaranteed not to ride up or pinch. Another reviewer writes: “The Hi Tide bottoms have been my go-to since last summer. I love the fit; the quality is always top tier and the color is beautiful.”

Boasting a sexy cutout that gives it a bikini-like vibe, this Lulus swimsuit is made with a blend of nylon and spandex that has an equal amount of support and stretchiness. One buyer writes, “I purchased this swimsuit in hot pink a few years ago and loved the way it looked and fit. I was super excited when I saw that Lulus offered a black option and purchased it immediately. I'm a huge fan of strappy one-pieces, and this one is perfect. It fits great and is flattering.” Throw in the $39 sale price and I’m sold!

This bikini top from Zara is fully lined and comes with a realistic-looking flower appliqué at the strap that's just begging for a beach day. The classic triangle silhouette is fabulously flirty, as are the matching bottoms, which are pretty cheeky if you're down to show some skin. Together, this set clocks in at less than $100, making it a super affordable buy that'll turn heads on vacation.

This Kelly Ripa-approved swimsuit is available in over ten colors and is loved by many for its flattering fit, ruched detailing and tasteful coverage. “This suit fits beautifully,” writes one Nordstrom shopper who made the splurge. “It is flattering, sexy with the high leg cut, and covers the bust area attractively. How often do you find an attractive suit that you are comfortable wearing around your kids and grandkids? I'm completely thrilled!”

It doesn’t get any better than a reversible, two-in-one bikini set. Boasting nearly 8,000 5-star reviews on Amazon, it comes with removable padded cups and features braided back straps for security. The best part? The bottoms are reversible to a solid color, so you can switch up your look as you pleast. “Best swimsuit ever," raves one buyer. "I've had my fair share of body dysmorphia throughout the years, and this is the first suit that I've actually wanted to wear in public without covering myself in a towel! It's a huge deal to find that, so thank you, Cupshe, for making a suit that has given me this confidence.” (Psst: It's available in a bunch of different colorways and prints!)

Chelsea Candelario, beauty and cultures editor, has nothing but good things to say about this wallet-friendly one-piece from Adore Me. “This one-piece has underwire and adjustable tie straps so it can really support the girls all day long,” she gushes in her review. “I also love how it shows off my curves—it’s a very comfortable design that I will definitely be wearing all summer,” she adds. Her favorite feature? The peekaboo keyhole cutouts in the front and back.

Stephanie Meraz, former associate fashion commerce editor, recommended picking up this affordable (and fashionable) bikini top for the summer. Made with a blend of performance nylon and stretchy spandex, it has a square-neck top with thick straps that should work wonders to keep the gals lifted. “If you prefer to take a dip in the pool or ride the waves sans extra support, the cups are removable,” she adds. Complete with the high-waist bottoms, this striped set is too good to skip.
