Finding the best swimsuits for your body type, especially at an affordable price, can be challenging, to say the least. So, the fact that Cupshe’s Bright Day Shirring One-Piece Swimsuit is Amazon’s number one tummy-control one-piece swimsuit, boasting thousands of five-star reviews and the gratitude of women who exclaim, “This made me feel good about my body!” and “I actually love this and I hate swimsuits,” means it’s truly something special. Read on to find out just how special and why this Cupshe bathing suit might end up being the best thing you buy this summer.

What a good tummy control one-piece swimsuit can do for you

“The best tummy control swimsuits can help you feel confident, stylish, and sexy,” says body positivity coach Lauren Salaun. “They make you feel more secure both inside and out since they’re designed to hold things in place a bit more, and they can even help you maintain better posture.”

According to Salaun, this Cupshe bathing suit is a great option for tummy control because of its thoughtful features. “There isn’t a ton of fabric on top, so you won’t feel like you’re wearing a full-on bodysuit—it still looks delicate and feminine,” she says. “Plus, it has the ruching, which is the gathered fabric at the midsection. Ruching is an ideal way to hide any tummy you don’t want to show off while also creating a streamlined shape in the process.”

These features are super flattering

“The biggest design element of this suit is the shirring,” explains Lily Ito, digital marketing manager at Cupshe. “Its placement creates a slimming effect with coverage and comfort.” That clever shirring (aka ruching), strategically created with a chinlon-spandex blend, is what creates this bathing suit’s tummy control magic, visually slimming the midsection without being uncomfortably restrictive. Plus, Ito adds, “the neckline of the suit helps accentuate the bust, and the cut of the leg creates an illusion of longer legs. That combination results in a bathing suit that is not only slimming but also works to highlight areas that you want to show off.”

The swimsuit also features adjustable straps and removable padded cups, and it comes in sizes XS to XXL. That makes it great for women of every size and shape. Speaking of which, these empowering bikini pics prove that everyone is swimsuit-ready.

Orange is the new black

Although the suit is available in more than a dozen colors, orange is, by far, the number one bestseller. Reviewers describe it as “gorgeous,” “beautiful,” “stunning,” and “awesome.” lto admits, “We have a hard time keeping this color in stock!” It’s flattering to all skin tones, and it’s the first choice for most buyers. After seeing how well the suit fits, though, many women decide to buy it in multiple colors. One user reports, “I like it so much, I just bought a second in royal blue,” while another confesses, “If this suit came in 75 colors, I’d have 75 of the same swimsuit.”
