I DON'T KNOW MY SIZE, HOW DO I CHOOSE THE RIGHT SIZE - YOUR SIZE GUIDE GIVES ANSWER IN SMALL MEDIUM LARGE OR S, M, L, BUT ON THE COAT PAGE IT ASKS SIZE AS A NUMBER SUCH AS 40 OR 42 ETC?
BEST ANSWER: For the sport coat, measure your chest and add 2 - 3 inches depending if you will be wearing a lightweight shirt or heavier sweater. Hope this is helpful. Exp: my husband's chest measures 42-43 and I order 46. That gives him plenty of room to stretch arms and not look too big in relaxed oosition.
