This is a denim jacket from the current season's Salon de Global Work, supervised by Ring Jacket. The color is navy, and the size is S (see the 6th image for detailed measurements). The material isn't particularly seasonal, and has a calm, elegant sheen, so I think it can be worn even in winter. You can wear it as a suit by pairing it with the matching pants, but it's a patch pocket design, so it works perfectly fine as a jacket on its own. I don't think it looks like something in the early 10,000 yen range, considering details like the side vents and the lapel stitching. I bought this this season, but it's only been tried on. I cut off the tags because I intended to wear it. Please understand that this item has been handled by someone else. The retail price is 13,990 yen. Here's the product description: Salon de GW 2025 【Material/Function】 Uses a stretch TR material that looks like denim. TR is a material with a smooth texture, firmness, and an elegant sheen, similar to wool (worsted). The inclusion of polyurethane in the weft provides elasticity (stretch), making it a material that doesn't feel constricting when worn. 【Design】 Similar sizing to the stretch TR series, patch pockets that can be used for a jacket-and-pants style. Half-lined for all-season wear.
