For the wedding of James and Tracy Bond, James Bond wears a form of semi-formal day wear called “black lounge,” known to the Americans as a stroller and to the Germans as a Stresemann. It is worn the same way as morning dress except a lounge coat replaces the morning coat (cutaway coat to the Americans). For business in England, black lounge was was traditionally worn alongside the lounge suit, having the same formality, but this practice fell out of favour by the 1970s.
Dimi Major of Fulham tailored the lounge coat, waistcoat and trousers. Bond’s lounge coat is most likely black, though there sometimes appears to be a hint of blue. The coat has peak lapels and buttons two, and it is tailored with straight shoulders with natural sleeve heads, a full, clean chest and a suppressed waist. Traditionally the black lounge coat worn in this manner has only one button, to mimic the modern morning coat’s single button, but two or three buttons are also correct styles. The cuffs have three buttons and there are double vents at the back.
The waistcoat is light grey and has 6 buttons. The narrow straight-leg trousers match the waistcoat in light grey and most likely match the other trousers in the film with a darted front and Daks-style button-tab side adjusters. Traditionally trousers worn with the black lounge outfit are the same as with morning dress: stripeed or checked, only in black, white and grey. Though Bond breaks with tradition, he does not insult it.
Bond’s white shirt from Frank Foster has a spread collar, front placket and double cuffs. The tie is a light blue-grey satin, tied in a Windsor knot. Bond wears black low-vamp monk shoes, though the traditional shoe would be an cap-toe oxford or balmoral, shoe or boot. Whilst the traditional hat for such an outfit would be a black Homburg or bowler, Bond brings along a black trilby. And since it is his wedding, Bond wears a white carnation in his lapel.
