I am not sure about what size this piece is but the measurements are as follows: shoulder to shoulder – 8 ½", length – 10 ½" from shoulder to bottom edge, width across chest – 11 ¼" and sleeves are 8 ¾" in length. This is from the 1960 -1970's and has a 3 button closure in front. A little fake pocket with hanky coming out. There are no rips or stains on this sweet blue and white striped blazer with blue piping. It is 100% cotton.
