At John Sport Couture. A denim-ish fabric with a slight stretch. Size large.

St John Sport couture navy jacket w/stud stars in gold & silver. Gold accent sleeves with zipper:23” long before turning back the cuff. Zip front. Length 23”. 21.5 across bust-line. It is perfection worn maybe once. Totally gorgeous. I do not know fabrics that well, but it has the thickness of a denim but a little stretched to it. I would say it fits like a 12/14. Perfect large
