Last month I talked about Bond’s first notched-lapel dinner jacket in Goldfinger, and in For Your Eyes Only we first see Roger Moore in a notched-lapel dinner jacket out to dinner and the casino. Moore’s black dinner jacket has a one-button front, jetted pockets, 3-button cuffs and double vents. Typically the buttons on a dinner jacket are covered in silk matching the lapels, but here the buttons are black horn like those often found on a suit. The trousers have a silk stripe down the sides and are cut with a flat front and straight leg.
Bond’s shirt has a spread collar, rounded-corner double cuffs and a pleated front. The cloth is white cotton with a tonal stripe, making this shirt similar to the dress shirt in Goldfinger. The shirt has regular mother of pearl buttons down the front. We also see Bond wearing some sort of cummerbund (see picture below). It looks like it buttons on to the front of the trousers rather than wraps around the whole waist. But it serves the purpose of a cummerbund: to cover the waist.
