Flattering in front of a white wall. I’m not sure if the illusion will work at the pool or beach though.

True to size- it is a flattering bathing suit

This product is wonderful. The white triangles give the illusion of perfect curves making you feel so confident it is tummy controlling, and I have larger chest area I felt very secure and covered. It feels very confident.

Good one-piece. It definitely gave me shape, but cut me off a bit in the thighs. Not my favorite bathing-suit. Material was decent but felt tight putting it on.
