Collars & Cuffs
I love the idea of detachable collar and cuffs. In the 1800-1900s most men wore under shirts so the shirt was protected from sweat except at the collar and the cuffs. It's said that in 1825, Mrs. Montague of Troy, New York tired of washing her husbands shirts because of his ring around the collar created the first detachable collar! By making a removable collar and cuffs, they could be washed separately so you didn't have to wash the shirt as often!
