Reviews Summary
Customers say these swim bottoms are comfortable, flattering, and provide excellent coverage. Many appreciate the wide waistband design that creates a slimming effect and stays in place during water activities. The fabric is described as soft and high-quality. Common feedback includes that the fit runs true to size, though several customers recommend sizing up if between sizes. Users love the variety of prints and colors available. Some mention the bottoms are slightly cheekier than expected but still provide good coverage. A few note concerns about thinner material in certain styles and tighter leg holes in newer versions.

    Best fit for comfort and coverage

    I have been looking for a suit specific to my issue- a rather gnarly C-section scar and resulting pooch- and this one is perfect! The band is comfortable on the scar but also keeps everything flatter (and flattering). Highly recommend if you have some of the same issues!

    Perfect swim bottom!

    I love this swim bottom! Quality fabric, soft and comfy on my skin, the right amount of stretch, holds its shape, perfect coverage. I can wear the medium or the large comfortably, but prefer the looser fit lately even though the measurement chart puts me in a medium. I have multiple colors and will buy more, I'm sure.
