This is a Maison Margiela knit vest, and I believe this item is rare as it's hardly ever available. The retail price was also quite high at 120,000 yen, and I think it's an item that, in a good way, has less of a typical Margiela feel. It's quite niche, but I think it's a very stylish item, so how about it if you like it? The knit has a distinctive weave, and it has a short, boxy silhouette.
