It took a few tries to get the sizing right but I’m so glad I didn’t give up because I love this bathing suit. The quality is amazing. Bathing suits are often lined in the front but not in the back; this one is lined on both sides! The fit and cut are perfect.

Love the classic silhouette and the leakproof technology. This is the only one piece that I can wear with no issues - the others are usually too large in the bottom, if they fit the top part. There should be a wider range for women with larger breasts. I don’t need to wear bigger than XL bottoms , but my bras are 8++ size. ( meaning xxxxl+)
