Tweed is a must have in your wardrobe this winter, and you don’t need to own a pipe or an Irish castle to make it work. We’re not talking the crusty stuff in thrift-store bins – Tweed has evolved. Designers like Billy Reid have modernized the cut so your boots and skinny pants fit right in. Nail the fit with a slim cut topcoat that falls above your knees like BILLY REID’S SUNDAY COAT now available at Diplomatic Immunity. This is how tweed’s done in 2012.
