J.Crew Ruched V-Neck One-Piece
WHY IT MADE THE LIST: This one-piece offers ample coverage thanks to its high back and lowrider-style bottom, but you can’t deny the sex appeal the plunging neckline adds. Plus, the ruching on the bodice makes it a candidate for best one-piece swimsuit for tummy control.
ADDITIONAL DETAILS: One thing to know about J. Crew: they don’t shy away from bold colors (like the radiant fuchsia and blue mist shades this one-piece comes in). We’re thankful for that, especially because swimwear is a great canvas for experimenting with colors and patterns you wouldn’t usually wear.
Andie The Mykonos
WHY IT MADE THE LIST: There’s no question about it: the Mykonos one-piece is stunning with its deep V-neck cut in the front and back. But even more impressive is how many options they give you to tailor it to your preferences—you can choose the fabric type, length, and bottom coverage in addition to the color and size.

La Blanca Island Goddess One-Piece Swimsuit
WHY IT MADE THE LIST: Remember how in The Sisterhood of The Traveling Pants four women with different body types all looked fantastic in the same pair of pants?

What we’re trying to say is that the classic silhouette of this one-piece swimsuit flatters any and all body types.
USER REVIEW: “This suit fits beautifully. It is flattering, sexy thanks to the high-leg cut, and covers the bust area attractively. The color is a jewel-toned green, which is striking. I'm going on a cruise next week and am positive I won't see another suit that color. How often do you find an attractive suit that you are comfortable wearing around your kids and grandkids? I'm completely thrilled with this suit.”

Highly recommend for moms who are up and down and in the water and holding kids and not able to lay perfectly on a beach chair!”
Summersalt The Marina

That and the price point are enough to get our attention, but it also helps that it’s insanely cute and comes in 44 (!) different varieties.
USER REVIEW: “Ladies, buy this suit! I have the hardest time finding one-pieces because of my long torso. I sized up to make sure it wouldn't be too short in the torso, and it fits perfectly. The ruching is really flattering and helps hide my "mummy tummy." The cobalt blue color is so pretty; really bold and classy combined with the ruffle and one shoulder. I'll be getting this in more colors!”
