Size is men's M. I am 177CM and 65-67kg, and it fit perfectly. I didn't have a chance to wear it, so I bought it new last year and only tried it on, then stored it in the closet. Original price: 25,000 yen 3mm/2mm I believe it's a beautiful item, having only been tried on, but please refrain from purchasing if you are looking for the specifications of a perfect new item or if you are very particular. Also, I will pack it carefully to avoid wrinkles as much as possible when shipping, but please understand that there is a possibility of wrinkles. I will also try to ship as quickly as possible, but I may not be able to ship on weekdays due to my work schedule, so please inquire before purchasing if you need it urgently. *Shipping is not possible from 6/23 to 6/27.
