This is a gorgeous jacket from Tommy Bahama. Full zip. This coat is NEW, without tags. It is guaranteed to be authentic and perfect. Marked L. It measures 26inches armpit to armpit, 35/36 inches from mid-collar to the end of the cuff, and 28 inches from the collar seam to the bottom of the back. (All measurements done across the back with the jacket laid flat). Please compare my measurements with a coat you have that fits you well. You will NOT be disappointed.
