How should I care for my new bikini?
The best way to lengthen the life of your bikini is to use RIVI Bikinis Active Wash. It coats your bikinis and keeps it protected from harmful chemicals especially chlorine.

To also keep your new bikini in the best possible shape we recommend that you avoid sitting on or up against rough surfaces- keep a towel handy and keep your bum comfy!

After a dip in the ocean or pool, hop in the shower and rinse off. Freshwater is the trick to keeping colors vibrant. Swimwear is not made to be thrown in the washing machine; instead, hand-wash your bikini with mild soap in cold water. Some colors may bleed so please do not mix light and dark colors while washing. Line dry or dry flat, do not wring, twist, or iron. Always avoid contact with oils, sunscreen, and heavily chlorinated pools.
