A silhouette pulled straight from the Sid side (hence the name!). The Sidney has a classic spread collar, with a roomier fit through the shoulders, chest, and arms to give it that borrowed-from-the-boys feel. The fabric is beautiful, too. We've long used an around-the-office portmanteau for it (royal + oxford = roxford,) since it’s lighter and dressier than a traditional oxford, with a more defined texture and a slight glow to the surface.
