Blue Industry

They are European collar measurements in centimetres, not chest sizes. A 38 is roughly a 15-inch collar and a small, 39 to 40 lands near a medium, 41 to 42 near a large, and 43 to 45 covers extra large and up. Measuring an existing shirt collar in centimetres, flat from button to buttonhole, gives the number to order more reliably than converting from a letter size.

A jersey shirt is knitted rather than woven, so the fabric loops instead of crossing at right angles. That gives it natural stretch, a softer drape and far more resistance to creasing, which is why it travels well and needs little pressing. It keeps shirt construction — collar, placket, cuffs — but wears with the ease of a t-shirt, sitting between formal shirting and knitwear.
