I have the book on Bond's clothing "Dressed to Kill", and they cover this issue in glorious detail. He wears Brioni suits throughout, including a Saxony in the office Interview with M scene and a muted blue windowpane in the Moscow arrival scene (Samsonite paid to provide his luggage in that scene, and they had to fudge it into the script: it's a bit incongruous that he's carrying two large cases of a type that are obviously intended to be checked, directly off of an arriving BA jet, with no jetway yet). His shoes are Church's, his ties identified as "woven silk", and the coat is IDed as a Brioni in cashmere. The costume designer for the last four Bonds was and is a woman named Lindy Hemmings (she's interviewed on the Die Another Day Special Edition DVD). She took some flak for the tie and ascot choices for Goldeneye, and you'll note that his subsequent films have him in very muted ties, no pocket silks, and no ascots. Brioni has made the Bond connection a very big deal, including issuing a book, and a poster that shows Brosnan on a T-55 tank with an AK74SU Krinkov assault rifle, wearing a marine blue nailhead single breasted. There you go, more than you probably wanted to know.
