To keep your shirt looking new and make sure it lasts a long time:
-Turn inside out before washing (this helps protect the print from getting scratched by zippers or buttons)
-Machine wash cold (no warmer than 86°F / 30°C) and with similar colors
-Wash on a gentle cycle with a mild detergent (DO NOT use bleach, bleach alternatives, detergent with enzymes, or fabric softeners)
-It's best to hang dry after washing, but you can also tumble dry with low to no heat (Do not use dryer sheets)
-Iron at low temperature and avoid ironing on print (either turn your shirt inside out before ironing, or cover the print with parchment paper)
-Do not dry clean
If your shirt arrives with water marks or press marks don't worry, these will disappear after a couple of washes!
