Have you ever gone to put on a collared shirt only to find the collar has lost its form and sags awkwardly around your neck? Reddit user PTKIRL noticed that by storing his shirts with only the top button clasped, the collar stays crisp, no ironing required.
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.
