The size feels like it's between S and M. It was a perfect fit for me, at 172cm and 60kg. I think it can be worn by both men and women! Sleeve length...Long sleeve Pattern/Design...Check Material...Cotton Length (from the collar seam): Approximately 59cm Width (pit to pit): Approximately 53cm Sleeve length (from shoulder seam): Approximately 61cm This is a sturdy gingham check fabric that can be worn in spring, autumn, and winter. I think it can also be worn in rooms with strong air conditioning in the summer! It's a beautiful item, only tried on, with no holes or scratches, and no signs of use. Please understand that this is a used item that has been stored at home before purchasing. m(_ _)m
