This is a summer jacket from Aquascutum. My impression when trying it on was that the stretch material makes it very comfortable to wear. The thin fabric also makes it very cool. I purchased it at a famous department store, but I never had the opportunity to wear it, so I'm offering it to someone who will. I believe it cost around 40,000 yen. The color is navy. It has side vents. It's a seasonal item. Get it while you can! It's listed as size M, but please refer to the following measurements: Shoulder width: 42cm Body width: 52cm Length: 71cm
