I received this question from a reader:
Why do my shirt cuffs keep fraying?
This is what I shared with them:
Fraying shirt cuffs is generally due to the shirt rubbing on something: a watch, a desk for those who spend time writing by hand, or a keyboard for those who spend time at the computer. You may want to choose slightly larger cuffs on your shirts, so that the cuff slides easily over the watch instead of getting caught on it. Even a very smooth watch can create friction that will wear on your shirt. When you write or type, lift your arm slightly, or roll your sleeves up first.
