In Casino Royale‘s black & white opening sequence, one of James Bond’s outfits is a navy blue linen suit made by an bespoke English tailor, not Brioni. Blue is the best of the dark colours for linen suits, which are most commonly found in lighter tones such as cream, beige and tan. Bond’s suit has soft shoulders and a button two front, with the high button stance that was popular at the time. The high button stance doesn’t function well when closed, but Bond wears it open anyway. The jacket has swelled edges, four-button cuffs, double vents and open patch pockets. The patch pockets are a classic feature on warm-weather suits as they don’t require a lining to be placed inside, and they go well with the suit’s more casual cloth. The trousers have a flat front, straight legs, plain hems and are worn with a belt.
The blue and white end-on-end shirt is likely a linen and cotton blend. It has a tall, two-button spread collar, front placket and short sleeves. Short sleeves shouldn’t be worn with a suit, even such a casual one, but short sleeves with a suit recall how Ian Fleming dressed James Bond in his stories. Though most suits should be worn with a tie, a casual linen suit is one of the few that can successfully be worn without one. Bond wears the suit with snuff (light brown) suede chukka boots and a medium brown leather belt.
Though the scene is in black and white, colour photos can be found in the book Bond on Set: Filming Casino Royale by Greg WIlliams.
