Love this stylish jacket & bought it to match the pants that I have on here for sale. I bought this outfit hoping to lose the weight I needed to - to be able to wear this but I didn't. It is super nice in my opinion. Measurements are - armpit to armpit = 21 inches. Sleeves measured from top of shoulder to end of sleeve is 24 & measurement from under collar  in back to bottom edge of jacket is 23 inches. Material is 84% Polyester- 15% Rayon & 1% Spandex. This jacket has an off centered zipper & also has slant zippered usable pockets.
