This woman’s blazer is by Hanna Andersson for size 14 Petite. The jacket is fully lined and is a houndstooth plaid. The material is a poly/rayon/spandex blend. There are no flaws. There’s a single cloth covered button under the collar, which I think can be described as a Peter Pan collar.

23.5 inches long

23 inches wide from under one arm to under the other across the back

18.5 inches between shoulder seams
