This grey Thom Browne 4-bar stripe wool blazer is lined with the label's signature red, blue and white pattern. Tailored in Switzerland, it's characterised by hallmark stripes on the left sleeve and features notch lapels, button fastenings, a chest welt pocket, buttoned cuffs, and two front flap pockets. Symbolically the number four is associated with self-fulfillment, which makes sense as you are sure to gain plenty from wearing this Thom Browne blazer.
