I believe I purchased this about 3 to 4 years ago. I haven't worn it much, and I've had it cleaned and stored every year. The size is S, but I usually wear M to L, and I could wear it without any problems. It has been treated with water-repellent processing at the dry cleaner, so you can wear it as soon as it arrives. *Please note that this down jacket is not Nishikawa Down.*
