St.John lightweight wool/silk coat w/piping, mint

Most beautiful coat in mint condition. Raglan sleeves, silk piping. Very lightweight, the fabric is part silk and part wool. Vertical piping provides a beautiful silhouette and slims. The size is marked 4, but the cut is generous: armpit to armpit is approximately 18.5”, length is 34.5”. Would work for size 6 as well.
