This is a Maison Margiela MA-1 bomber jacket. I purchased it from a vintage clothing store, but I'm selling it because I haven't had the opportunity to wear it. The size is 46. Based on the tag, I believe it's from the design team era, which is between the "Honnin-ki" (original) and Galliano periods. I haven't worn it myself, but there are some signs of wear and wrinkles from the previous owner.
