The WS-100 Paisley Woven Shirt with Cufflinks

Jacket size = your chest in inches, measured around the fullest part with arms relaxed. Length follows your height: S (short) about 5′4″–5′7″, R (regular) 5′8″–6′0″, L (long) 6′1″ and up. A 42R is a 42″ chest, regular length.

Drop is the difference between jacket size and trouser waist. Classic and regular fits are usually a 6″ drop; slim and modern fits a 7–8″ drop.

Sizes 34–60, in short, regular and long. Sleeves and trouser length are adjusted in store.

Neck: measure around the base of the neck and add ½″ so a finger fits under the collar. Sleeve: from the centre back of the neck, over the shoulder and down to the wrist bone. A 16 / 34–35 is a 16″ neck with a 34–35″ sleeve.

Waist: measure where you wear your trousers, usually just above the hip bone. Inseam: from the crotch seam to the bottom of the leg, inside the leg. Dress pants are hemmed to your length and shoe in store.

Stand on a sheet of paper, mark heel and longest toe, and measure the distance. Between sizes? Take the larger one and try both in store.
