Sid Mashburn Button-Down Collar Checked Cotton-Madras Shirt
From MR PORTER
Sid Mashburn's checked shirt is tailored from Indian cotton-Madras, a fabric defined by its slubby, tactile finish. It has high armholes for easy movement and a hem that's long enough to stay tucked. The button at the nape – traditionally used to keep a tie in place – is a considered detail.
