Reviews Summary
Customers say these bikini bottoms offer excellent coverage while staying flattering and secure during water activities. The low-rise design provides good coverage without being too revealing, and the bottoms stay in place during swimming, beach activities, and active play. Many appreciate the soft, quality material and comfortable fit. Several note the textured fabric works well for lighter colors. Common feedback includes that these bottoms run small, with many recommending sizing up for the best fit. While most find them flattering and secure, some mention tight elastic around the waist and legs can create unflattering bulges.

    Blue bottom

    I was pleasantly surprised as usually order high rise, but these provide modest coverage and actually covered my bottom more that the high rise from Nani as the shape is different. I’m 122# Ang got XS as prefer snug fit for swimming.

    Great Bottom

    Fits great and very well made. I’m 5’2 about 124 lbs (athletic build) and I got the medium. It fits perfect without digging in. More than I usually spend on a swimsuit but it looks great with the top I got from Nani.

    Flattering Tankini

    This tankini is flattering! I even got compliments the first time I wore it. Plan on buying more in different colors!
