This is a rare vintage MP piece that is embellished with patching, overstitching and edge stitching as well as some distressing on edges.  The buttons on the front are all different colors.  It is a soft, comfortable timeless piece that I have worn as a jacket and also buttoned as a top. The bottom back has a very interesting 5 inch vent detail. 

Dimensions are:

pit to pit 21 inches (42 circumference)

bottom measures 22.5 across (45 circumference)

length (shoulder to bottom) is 22.5 inches

sleeve length from shoulder is 18 inches

Note: this piece retailed for $625
