Mark Long Sleeve Polo from Vivienne Westwood, knitted in black wool. Confirming the earlier note: this is a knitted polo, cut as a fine-gauge pullover rather than a jersey piqué polo, with a soft spread collar and a three-button placket. Straight, regular-fit body runs with set-in sleeves and sits close without pulling. Wool knit carries a smooth, dry hand with a slight matte surface, holding the ribbed collar, cuffs, and hem in shape. Tonal buttons and an embroidered orb at the left chest finish it. Wear it with the collar open over a tailored trouser, or layered beneath a coat.
