Lasses, if the wrinkles fall out of your favorite wrinkled poplins, bundle your shirt into a ball straight out of the washer and set on top of your dryer. Let the shirt dry in the bundle. Once dry, iron the placket down as needed.
No need to worry, lads! All lads’ shirts, as well as any lasses’ flannel, denim, or linen shirts, are never wrinkled!
