I literally do not know what this piece of clothing was made for. It's a reversible, 1960's era vest, with an orange fabric side and a green plaid wool side. Buttons on both sides. The colors and cut make me think vintage uniform (grocery store?) but it's really nicely made. Tag inside says: Made from a Frost Line Pattern. Odd. But cool. And if you're a stylist, maybe you could use it for a pattern. Men's 40 or Medium chest.

Measurements:

Length: 24"

Chest (armpit to armpit): 20"

This item is sold from a vintage boutique in Dover, NH.
