This suit features a tummy control panel for a more flattering figure. The spandex in the tummy control liner will deteriorate quicker in chlorine than the actual Krinkle® fabric. Please follow proper care instructions. Once the tummy control liner eventually fails many customers carefully cut out the lining and continue to get many more months of additional wear. The Krinkle® fabric is not transparent when wet and this suit can be worn without the lining present.
