Giacca Wool Coat

Women’s black wool peacoat. Missing 3 buttons on front and one on left sleeve- see photos. I have one of the missing buttons, and the coat has another sewn inside for replacement. I’m not a sewer but maybe you are! Also has a loose button near top- perhaps this could be removed for replacement of the third missing on the front. Otherwise great condition. Could maybe use a sweater shaver like most wool coats.
