Salvatore Ferragamo Vintage White and Red Plaid Short Sleeve Button Down Shirt

Excellent vintage condition, only missing top button which you do not need to wear the shirt No tears or stains This is a vintage shirt and therefore I do not have any information on it. Based on appearance, I am assuming it is a woman’s shirt. No fabric tag, based on feel, I think it is silk. No size tag, based on measurements, I am listing it as a medium. Shirt has been cleaned. Measurements are approximate: PTP: 20” Shoulder to hem: 25”
