This is a handy tip to keep in mind when hanging up your clothes straight out of the dryer. If you only button the top button the collar can keep its normal shape and doesn't end up hanging to the sides. It's certainly not going to make a wrinkled shirt that has sat in the dryer for three days look good, but if you hang it right away with this method, the collar stays straight and crisp.
