This is a vintage adult size small cotton knit official Girl Scout Sweater. It is a cable knit pattern with a stiched GS logo on the upper left of the front of the sweater. It is 18 inches across the chest. 27 inches from neckline to the bottom edge. Sleeves are 29 ionches from the center neckline, 18 inches from the shoulder seam. It is in like new condition. I believe it is 100% cotton, as washing it returns it to shape after wearing may stretch it.
