Vintage 80's M/L rainbow plaid long sleeve button blazer jacket

Vintage 80's M/L rainbow plaid long sleeve button blazer jacket! By Eccobay. So colorful and fun! Three buttons in front. Front pockets. Lightweight. V-neck with collar. There is a faint spot in front (see last photo). I have plans to wash and try to remove the spot still. Otherwise wonderful. Happy to answer any questions :) Measurements: Pit to pit - 20 1/2 inches across. Length from shoulder to hem - 26 inches. Shoulder seam to shoulder seam - 16 1/2 inches across. Shoulder seam to sleeve end - 24 inches.
