care instructions

FP jeans are here to stay. Treat ’em right and they’ll love your booty right back for years to come. Please see below for the best advice on how to care and upkeep your FP denim.

  • flip your jeans inside out and pop them in a cold wash – quick cycle or hand-wash (wash with like colours)
  • use a mild detergent (or dedicated denim detergent if you have it!)
  • dry flat in shade
  • steam or use a hot iron to straighten out any creases (be sure to flip those jeans inside out and unbutton them)
  • don’t dry clean! use mild detergent and toothbrush and lightly brush to get rid of any stubborn stains
  • don’t bleach (duh!)
