I have heard many many times that a jackets sleaves should leave about 1 inch of shirt sleave exposed. An equal number of times I have asked why? And most of the time the answer is simple that that is the way it is done.
I am quite curious as to how the tradition, rule, what ever you may call it of leaving a portion of the shirt sleave exposed came about? One would think that at any given time in early history with the cost of clothing you would want to protect it from stains etc.
So I put it to the learned rabble, why must ones jacket leave ones sleaves vulnerable to the elements?
