Block-style short-sleeve Shirt with scoop hem and grandpa collar. Patch chest pockets.
To maintain the crinkle effect, wash in cold water. Gently twist garment to remove as much water as possible and then tie in a knot while it is still twisted. Leave it like this for 2 minutes, then untie the knot and lay garment flat to dry.
Do Not Iron.
If it doesn't need washing but someone accidently ironed out the crush (yes this happens often), simply give the garment a light spray with water, twist and re-crush with hands.
