The standard collar amongst the English shirtmakers is the spread collar, and it’s the collar Bond wears more often than not. If it’s wider than a point collar and narrower than a cutaway it’s safe to call it a spread collar. A moderate spread flatters almost everyone and is always a safe choice. They’re great with a suit and tie, with a dinner jacket and bow tie, or open, as long as the collar isn’t too wide.
Turnbull & Asser made a wider spread for Sean Connery, whilst Frank Foster typically made a rather moderate—but tall—spread for Roger Moore. Sulka made a smaller, moderate spread for Pierce Brosnan in GoldenEye, and Turnbull & Asser made a similar spread for Tomorrow Never Dies. For The World Is Not Enough they made a wider spread, and Brioni continued with the wide spread for Die Another Day. Daniel Craig wore Brioni shirts with a more moderate spread in Casino Royale and a similar collar from Tom Ford in Quantum of Solace.
Apart from the obvious differences of length, height and spread width, there’s the matter of tie space. It’s the quarter-inch to half-inch—or more—space between the collar leaves where the collar meets at the neck. Bond’s spread collars almost all have tie space, with the exception of the Brioni spread collars and Roger Moore’s brown stripe, double-button-collar shirt in Live and Let Die. Even with a very wide spread, a little tie space will help the knot to stay in place. Without it the knot often slips down and reveals the collar band above it because the collar leaves will push down the knot. A collar band with tie space is usually angled so the band will not show above the knot. Tie space plays just as large a roll in how large a tie knot can be worn with a collar.
