For his dinner with Bond in Goldfinger, M wears the least dressy of all dinner jacket styles: the double-breasted, shawl collar dinner jacket. It’s the type of dinner jacket that’s most like a smoking jacket. I can’t tell for certain it’s double-breasted, but from the very wide lapels and the bunching of the breast pocket it looks like he is wearing a double-breasted dinner jacket unbuttoned. M’s black dinner jacket has natural shoulders and roped sleeve heads, and the sleeve cuffs have four buttons and a satin silk turnback that matches the lapels.
M’s dress shirt doesn’t have any fancy details, but it may have been made in silk to set it apart from an everyday shirt. It’s slightly off white, which could be a further indicator that it’s silk and not cotton. It has a spread collar and double cuffs with edge stitching and a plain front with mother-of-pearl buttons. The bow-tie is black satin silk in a thistle shape. He wears a puffed white handkerchief in his breast pocket.
