Helpful review: “The suit is made of high quality stretch material and is great for curvy women who are somewhat smaller on top. That’s due to the halter top style that you can tie up tight around the neck.

The bottoms fit perfectly and provide just the right amount of coverage. No wedgie creep with these bottoms!”
