Navy double-breasted blazer by Ralph Lauren. It was a favorite of mine, but I didn't wear it much. After surgery, I lost 20 kg, and my body size has gone down, so I'm letting it go. The size is 40, which I believe is equivalent to a Japanese L size. I will write down the measurements, but since they are amateur measurements taken while the item is laid flat, there may be some errors. Thank you for your understanding. Shoulder width: 49cm Body width: 53cm Sleeve length: 61.5cm Length: 78.5cm Thank you very much. - Brand: Ralph Lauren - Color: Navy - Style: Double-breasted - Country of Manufacture: Canada - Model Name: Lauren Thank you for looking.
