How do I care for my JAMS by Jillian Bikini?

  • Hand-wash with a mild detergent & in cold water only
  • Hang dry inside or in the shade, do not dry in the sun, colors may fade
  • Do not use a dryer, dry clean, iron or bleach
  • Do not roll up your wet bikini or wring it out
  • Try to stay away from rough surfaces as it may pull on the fabric
  • A high amount of chlorine can ruin your bikini, we recommend you wash it right after use
  • Certain sunscreens and tanning lotions may damage your bikini

We do not accept worn or washed items for return
