Cashmere and Wool Blend Button Up Coat

What a beauty this is! This coat is really gorgeous, but she does have one or two small flaws. Firstly, she clearly could use a dry cleaning. I tried to get out the wrinkles but was afraid to put an iron to it. And, sadly, the steamer didn't do anything at all. The second thing is that the second button is missing. Because there is a placket covering the buttons, you could probably get away with putting any button of the same size there. Or, I would take off the top button and sew it onto where the second one should be. That's just me because I don't wear my jackets done all the way up. Overall, this coat is in excellent preloved condition, with the exception of the button. P2p is 19". There is no size tag, so I'm guessing a size medium. Any questions at all, please ask.
