The formal shirt that shows up when the invitation is black-tie and the room matters. Pleated bib front for structure through the placket. New Kent collar sits well under a bow or a satin-point tie. French cuffs finished for cufflinks, with four open holes at the front for tuxedo studs.
Two-fold cotton in the twill lets it press flat and stay crisp through a long evening. Fitted body: takes the drape close through the chest without pulling at the shoulder.
