This is a thin knit jacket from Marker (made in Japan, 55% acrylic, 30% nylon, 15% wool). It's a soft knit material with navy and dark green stripes and gold buttons. The knit is loosely woven, and the front is double-layered so it's not see-through, but the back is single-layered and somewhat sheer. There's a button on the underside of the collar, and you can wear it like a cardigan by fastening the top button without folding the collar (see image). Regarding the fit, the shoulder width and body width are slightly slim for a size M, and the sleeve length is a bit long, feeling more like an L. It's quite stretchy, so I think the longer sleeves are pulled up to balance the silhouette, compensating for the narrower shoulder width. As for the condition, there are some clumps of fuzz in places, but it's unclear whether this is part of the original design or due to aging. There are no noticeable stains or damage like pilling or fraying. ■Size 〇Manufacturer's size: 1 (equivalent to M, suitable for people around 170cm tall) 〇Actual measurements (cm) Shoulder width: 40 Body width: 42 Sleeve length: 75 Length: 71 *Please allow for slight variations due to manual measurement. ✅️I am also selling this item elsewhere, and it may be removed suddenly.
