Charles Tyrwhitt's most popular fit is their Slim Fit, which flatters most body shapes, tapering gently through the waist. Their morning suits are woven in a herringbone design that will never go out of style. Not surprising that for these creations they've harnessed the expertise of some of the world's most renowned mills. It's all about premium fibres and expert tailoring when it comes to this waistcoat. The soft fabric, woven at Italy's prestigious Barberis mill, is cut to an elegant double-breasted profile. It fastens with three buttons and is fitted with functioning welt pockets.
