We recommend washing your swimsuit after contact with chlorinated or salt water with cold water, lay flat to dry, and do not iron.

For all power mesh dresses and swim, dry clean only.

Due to the delicate nature of the hand embroidery, please note that over time, there may be imperfections (loss of crystals).
