This is a Maison Martin Margiela 04SS vest. I purchased it on the secondary market. The calendar tag was originally missing, so the details are unknown, but I believe it's a women's size based on the dimensions. I believe it's authentic based on the design and the quality label, but please make your own judgment before purchasing. I often hear about return scams with high-value items, so I will not accept returns. Shoulder width: 38cm Width: 42cm Length: 63cm Please note that these are amateur measurements, and it was difficult to determine the exact measurement points, so please consider them as a reference only.
