All of our shirts are made from 100% cotton, which means they will shrink when using a dryer on high heat. We took into account this fabric shrinkage when creating our patterns, making the shirts slightly larger. An unwashed Pladra may tend to fit slightly bigger and longer. When machine dried, shirts on average shrink up to 1'' in length and 1'' in width, but these numbers are dependent on how you care for your Pladra shirt. If you like the fit of your off the rack (unwashed) shirt, hang dry or use a low-heat dryer setting for less or no shrinkage. If your shirt originally fits too long or big, use a slightly higher drying setting to shrink it to your liking. By building-in shrinkage to our patterns, we give you the ability to customize the fit your Pladra.
