I really liked the shirt. I had it in several styles. It has kind of a mandarin collar with a V-neck. You could close it all the way at the top, but it is missing a button. Didn’t realize that before. I don’t see any stains or anything like that. It’s pretty much perfect. About the button, I couldn’t imagine that you would ever want to button it all the way up, but that’s me. It looks like it would just need a regular button. I took a picture of both the button hole and where the button would go so that you can see it. Nothing too interesting or fancy. I hope you like it.
