After a few wears folded up and artfully placed in the back left pocket of my various 501s (I know, I need to diversify my denimz) pocket squares start getting some serious creases. The simple solution: Wash the damn thing. Add water, snap out the excess, and hand to dry. My shower curtain rod does just fine. The fabric ends up wrinkled overall, but loses most of those hard lines from being sat on. Repeat the process and you’ll end up with a softer square to lightly dab the sweat from your brow after an energetic jog up a half flight of subway stairs.
