The notched lapel dinner jacket gets a lot of hate from clothing aficionados, however Bond has worn a notched lapel dinner jacket on a number of occasions. In all Bond has worn 7 dinner jackets with notched lapels. People who argue against notched lapels on a dinner jacket say that they are not formal enough for a dinner jacket or they make a dinner suit look too much like a business suit. Notched lapels are easier to make in mass production since they use the same pattern as a regular suit. Peaked lapels are the most formal style of lapels on a dinner jacket and come from the evening tailcoat. Slightly lower in formality is the shawl collar, originating from the smoking jacket. The notched lapel is even lower in formality, and since people mostly wear dinner jackets in formal settings the notched lapel is out of place.
James Bond is first seen wearing a notched lapel dinner jacket in Goldfinger when he is having dinner with M and Colonel Smithers. The notched lapels are more appropriate here because it’s a private dinner, however Bond’s company is better dressed in shawl collar dinner jackets. Not much of Bond’s dinner jacket can be seen, but since it is single-breasted it can safely be assumed that it has a one-button front. The cuffs have 4 satin-covered buttons. The lapels are faced in what looks like dark blue satin, which would means the suit fabric is probably midnight blue. Nothing below the waist can be seen.
The shirt and tie are the same as worn with the white dinner jacket at the beginning of the film. The bow tie is black satin (contrasts slightly with the blue satin lapels) and the shirt is a white-on-white stripe with a pleated front, mother-of-pearl buttons and double cuffs. And for the last time until GoldenEye 31 years later, Bond wears a pocket handkerchief with his dinner suit. Here it is a folded white linen square.
