Runs Small

I really wanted these bottoms to work out because I think this company’s commitment to sustainability is admirable. Unfortunately, these bottoms didn’t quite work out. For reference, I’m 5’7”, 135 lbs, and usually a size medium. I tend to be curvier in the hips and thighs with a smaller waist. I ordered a medium and a large because I read reviews that these run small. The medium was WAY too small and the large was too small as well. I loved the fit around my midsection, but on my hips and thighs these bottoms weren’t flattering on me at all. The edges (seams) of the suit bottoms were not flexible at all and made my skin bulge around the sides. I even tried stretching the seams out to no avail. I did really love the fabric quality, feel, and style, it just wasn't friendly to my curves.

Extremely flattering bottoms

Love these bottoms! Material is incredibly soft. Looks very flattering. Love how it shapes my body and gives that little bit of coverage for the stomach! Wore with the Sienna top for my bachelorette pool party!
