I purchased this about six months ago. The size is S, and there are three buttons on the right shoulder. I wore it once at work after purchasing it, but the size didn't fit, so I'm selling it. As you can see in the third photo, there is one stain. There are some wrinkles from storage. Please refrain from purchasing if you are concerned. I have checked it as carefully as possible, but there may be minor oversights. Please purchase only if you understand that this is a used item. There are no smokers in my household. I do not have any pets. I do not accept price reductions, returns, or complaints.
