I purchased this at an Isetan sale 2-3 years ago, but I haven't had a chance to wear it and it's been stored in my closet. I removed the tag, but it's new. The size is 3L, but I think it's a bit small. Measurements (laid flat): Width (armpit to armpit) 54cm, Sleeve length 59cm, Length 85cm. Please allow for some margin of error. Thank you for looking.
