Colleen Quen Couture Gunmetal Gray Dressing Jacket.
Looks good, fabric is silky, has a muted satiny sheen to it. Pre-owned, but in a very decent condition, no worn out on edges, no holes or loose buttons that I noticed.
Jacket doesn't have a tag with size information.
Shoulder to shoulder 17", underarm to underarm 18". (Measure yourself on the back)
Falls about higher third of thigh.
