The size is listed as M, but it also says 2 or 3. This is a 4-piece set. It's very old, and about 30 years have passed since it was purchased. Please refer to the images for the condition. There may be other stains, etc., that I haven't noticed. I will fold it up small for shipping. #PLEATS PLEASE #ISSEY MIYAKE #プリーツプリーズ #イッセイミヤケ #三宅一生 #Yakumi Shop
