Bond wears a midnight blue dinner jacket for dinner at the Eiffel Tower in A View to a Kill. Dinner jackets are only appropriate in the evening but this scene takes place during daylight. Since Bond has just come from the Royal Ascot (which takes place in June) it should be around the time of the summer solstice when the days are longest, thus it may very well be after 6 PM. Since there is ample daylight the dinner jacket looks more blue than black. The dinner jacket is double-breasted and, from what I can see, has 4 buttons in a keystone formation with the bottom 1 to button. The jacket is cut with a slightly draped chest, soft shoulders and roped sleeveheads. The black satin peak lapels have a buttonhole on both sides, and the jacket has double vents, straight jetted pockets and 4-button cuffs. In some shots of the stuntman a blue lining and belted trousers can be seen. But that doesn’t mean that Bond wears a belt with his dinner suit trousers, something typically out of place. The trousers have a black satin stripe down each leg.

The white dress shirt has a spread collar, pleated front, rounded-corner double cuffs and regular mother of pearl buttons down the placket. The bow-tie is a classic thistle shape.

This dinner suit sold at Christie’s in South Kensington on 17 September 1998 for £4,600.
This suit does not have a four button front. It has a two button front with one to fasten.
Stuart, double-breasted suits are typically noted by the total number of buttons, not rows of buttons.
Yes, I know. There are only two buttons, it is not a keystone figuration.
No, there are indeed 4 buttons in a keystone arrangement.
Oh yes. Sorry about that. I have however seen two button double breasted dinner jackets
