Bikini Care

How do I take care of my new bikini?

- Hand-wash it in cold water using a mild soap right after each use.

- When drying, let it bask in the shade—no direct sunlight, please!

- Be gentle and avoid twisting or wringing it out while drying.

- To keep your colors vibrant, try to steer clear of heavily chlorinated pools.
