This is a long dress by Issey Miyake. It's quite old, but the elastic in the sleeves is still strong, and the fabric is high quality. Despite its age, it still has a stylish design. It's a size 9, but it's roomy, so it should fit a size 11 or 13 as well. Since it's old, there are some stains if you look closely. I've shown them in the 7th photo. This is a piece I've cherished. I hope someone who will cherish it can wear it. Thank you.
