This is swim compatible but it's not lined so if you prefer a sexier look it's perfect. My bikinis are made similar to pole dance wear so they fit securely and still look really cute. The flat measurement isn't entirely accurate because there is a lot of lingerie elastic in this design so these bottoms fit a size MEDIUM or a 32-34 inch waist best. The top is fully adjustable it can accommodate a larger cup or be scrunched smaller on the adjustable straps. This is a dark base with neon splatter paint all over and bronze color glitter all over. The glitter is part of the color pattern and doesn't transfer.
