This is a nylon jacket from Maison Margiela. It's designed to be worn like an open-collar shirt or blouson, making it very versatile. The size is a rare size 50!! This simple jacket with the four-stitch tag on the back is quite rare! I bought it, but I haven't had many opportunities to wear it, and I'm selling it because I bought another jacket and no longer need it. Color: Black Width: 61cm Length: 69cm It looks great as a single jacket, but it can also be worn as an inner layer under outerwear, blousons, stand-collar coats, trench coats, Chester coats, knitwear, and cardigans. It can also be worn over a T-shirt, making it a very versatile item.
