Reviews Summary
Customers say this swimsuit has a flattering fit with flattering ruching and offers versatile styling with removable straps. Many praise the quality fabric, comfortable support, and how it makes them feel confident. The ruching effectively shapes the midsection, and the suit works well for various body types, particularly those with larger chests. Common feedback includes that sizing runs small—most recommend sizing up for comfort. Some note the compression is quite snug, and a few wish for different neckline options or longer torso lengths. Overall, reviewers love the classic design and quality construction.

    Better than expected.

    I bought this suit in the green and it is soooo lovely.

    I sized up two sizes based on the feedback and I’m glad I did. I find that generally swimsuits fit smaller so adjusting by two sizes means a swimsuit that fits well and doesn’t cause flesh to bulge.

    Beautiful, but I had to go up one full size

    I got the floral one and it is stunning. I am 5’4”, 34DD and 135 lbs. I always wear a Knix M+ in everything I have ordered, but because of the compression I had to exchange it for a L+. It really is beautiful!
