Thom Browne Cashmere 4-Bar Sweater Vest

After putting old suits in the tumble dryer to try to shrink them, Thom Browne fell in love with the concept of suiting, seeing formalwear not as a rigid set of rules to be followed but as a loose concept that’s destined to be deconstructed and played with. It should come as no surprise, then, that the designer’s eponymous label is so well-versed in creating pieces to complement your favourite tailored separates – like this classic cashmere sweater vest.
