Vintage lightweight peacoat blazer, blue

I loved this jacket!! Vintage lightweight “peacoat”, blue. No brand or size but I bought it second had in the 90s and it’s still an awesome jacket!! Butterfly collared. Button down. Buttons on cuffs and deep pockets in front. Pre-loved. Gently used. Fits a medium. Fall vintage retro style perfect for sweater weather pumpkin spice leaf peeping autumn season! Will be on trend for back to school.
