Does your men’s shirt say ‘pre-shrunk” but it shrink in the dryer anyway? Aaron Marino of alpha m. has done it, and you’ve probably done it too. Don’t trust anything that says ‘pre-shrunk’.
Take special care when drying clothes if they are the perfect size. Cotton shirts will shrink if put in the dryer when wet, and there is nothing you can do to un-shrink them. Pre-shrunk? Don’t believe the hype!
