I purchased this at a Kintetsu Department Store. It's a finely knit sweater. The neck can be folded over for wear. I wore it for a short time twice, and then had it dry cleaned and stored at home. It's a size M, but it's slim and feels close to a size S. It has been dry cleaned, so there are some fold lines on the back, but there are no problems with wearing it. Please refrain from purchasing if you are concerned about this. Shoulder width: 30cm, Pit-to-pit width: 39cm, Length: 54cm, Sleeve length: 59cm Measurements are taken flat. Please allow for some error (as it is a knit, it will conform to the body). Thank you for looking.
