This jacket is gray and is lined in black.

Marked M.

It measures 23 inches armpit to armpit, 35/36 inches from mid-collar to the end of the cuff, and 30 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 jacket you have that fits you well.  You will NOT be disappointed.
