Vintage JH Collectibles blazer, periwinkle, 100% wool,2 button front, size 6?

The color of this blazer is GORGEOUS!!! Periwinkle! This all wool blazer is in very good pre loved condition. Some fading of the lining (last photo) - that’s it! I can vaguely see the remnants of a union label (see 2nd to last photo), so this is vintage and made the USA! No size label, but I’m guessing it’s a size 6 (see measurements below) 19 inches pit to pit 29 inches length 13 inches armpit to cuff
