The size is a so-called (46) L, with a length of 60cm, sleeve length of 61cm, shoulder width of 43cm, and body width of 47cm. It fit me perfectly, and I'm 179cm tall with an average build. It might also be suitable for someone a bit smaller. There are no stains or marks at all. I used it in a business setting, but I think it can also be worn casually. It has been dry-cleaned and I haven't worn it this year. The shape and pattern are classic, so I think it will last a long time. Please feel free to comment if you have any questions.
