VINTAGE Jack Winter Knitsport Plaid Button Down Shirt

Vintage late 70s-80s Jack Winter Knitsport plaid button down shirt. Features timeless plaid design in red, white, & blue hues. Short cuffed sleeves, button front design, & mandarin collar. Size & care tags are missing but most likely it is a poly/cotton blend. In very good preloved condition with minimal normal wear consistent with vintage age. I have listed as a size large based on the following approximate measurements lying flat: 19.75” from pit to pit & 25” from shoulder to hem. Bundle to maximize shipping!
