This is am absolutely immaculate blazer. 2 button, single vent. I am listing several of my very best Sport Coats and Blazers. A year ago, I decided to lose weight and ended up losing over 70 pounds. Needless to say, none of these will fit me any longer. Each one has been meticulously inspected and all of them are fresh from the dry cleaners. You can buy these with complete confidence that they are of superior quality and condition. Some have been worn only a few times. In the photos you will find a measurements photo that depicts the measurements of each one taken individually.
