Our best-selling one-piece swimsuit in brand new shades! Equal parts sophisticated and sexy, the Echo One-Piece hugs your body and highlights your hips with a high-legged cut and minimal back coverage. The ruched side detail is met by moderate bust coverage and supportive shoulder straps. Super soft and super stretchy, this one-piece doubles as a bodysuit for an effortless beach-to-bar look. Just like an echo, you will want to repeat this purchase in every shade.

This is legit the best swimsuit I have ever purchased. Small boobs, stick figure, NO PROBLEM. It accentuates your waist and makes you look like you have curves even if you don't. I can't lie - it may not be family appropriate, but you will look so good you won't care. #sorrymomanddad.

Hi the swim is soft and beautiful! However I went swimming and the material expanded and was extremely big on me in the pelvic region. Almost appearing like that was an excess amount of fabric. I purchased an xs too! Can’t imagine anyone smaller than me fitting into this suit.

Thong one piece

The suit fit perfectly. I am 5’ 11”, 126 pounds with a long torso and the large was perfect. Material quality is very good. The one drawback is no padded cups but in the black suit color it will be easy to add.

Want one in every color!

Such a great quality suit, would def buy again. I even wore it as a top a few times. The best fitting one-piece I own aside from some extra bunching fabric right above the thong.

Most comfy and flattering bikini

This bikini is gorgeous it is super soft and gives the appearance of a smaller waist and longer legs. It fits true to size and is very cheeky.

Great Suit but one thing to consider

I love the suit! The material is soft & luxurious. I first ordered a large, but needed to exchange it for an XL and customer service was great & quick. I will say that the cut of the suit can create fat rolls because it’s fitted at the waist. You can adjust “the waist part” by moving it down or up to reduce the fat roll, but it does change the look of the suit. It’s just something to consider if that would bother you. Otherwise, I totally recommend it! US dress size: 12,H: 5’9, W: 200 lbs

This is a flattering, sexy one piece for just about every body type. My only issue is if you’re ***** on top, you need to be sure you’re always covered. Might need a little spray glue to keep the top in place to avoid a wardrobe malfunction.
