In On Her Majesty’s Secret Service George Lazenby takes the black and white Prince of Wales check suit that Sean Connery often wore and adds a blue overcheck. The black and white check pattern part is slightly off from a typical Glen Urquhart check. The overall large check is taller than it is wide, as it typically is, but the finer horizontal lines are emphasised. The cloth is most likely woven in an even twill like the standard Prince of Wales check is. One interesting thing that tailor Dimi Major does is he rotates the cloth 180 degrees on adjacent panels. This can be seen by looking at the horizontal stripe sections in the pattern. On the lapels a white stripe in on top, on the front body panels a black stripe is on top and on the sleeves a white stripe is on top again. Some tailors match their checks this way instead of the more logical way of matching them in all the same direction.
The illustration below is the closest I can come up with to figuring out the atypical check pattern. Click the image to enlarge:
The button two suit jacket has soft shoulders, a clean chest and a close cut overall, with a slightly shorter jacket length, though not as short as what is fashionable today. The cut is in line with the current fashions of then and now, though unlike today’s fashionable suits this suit does not look shrunken. The jacket is detailed with three button cuffs, steeply angled hacking pockets with a ticket pocket and double vents. The front edges of the pockets are more rounded than the way most tailors make them for extra flair. The double vents are deep and have an outward flare. The suit’s buttons are made of dark grey horn. The trousers have a darted front and narrow, straight legs. This suit is full of late 1960’s English flair and is the most fashionable suit Lazenby wears in the film. It is the most fashionably-dressed we’ll see Bond until Roger Moore gets settled in the role.
The sky blue shirt made by Frank Foster picks up the blue windowpane in the suit. The shirt has a point collar and single-button cuffs. The navy knitted tie has a soft, dull look with slight pilling that would suggest wool as opposed to the standard silk. Lazenby ties it in a half windsor knot. The shoes are black.
