Roger Moore's lasting impression as James Bond was in those bigger 70's styled bow ties which generously flared top and bottom. More than any of the day wear it's the evening wear that we seem to remember best and in Moore's case, the cream/off white dinner jacket in a wide peaked lapel is the most iconic image.
Sean Connery's Bond, on the other hand, was in most cases much more reserved in the evening. In the tropics he still took his white and cream dinner jackets but more often than not his bow ties are a little slimmer, a little sleeker and his lapels a little less generous. For those of you seeking a more subdued evening wear look, for those of you who would like to say more with less - you may want to switch to a slimmer black bow tie in either a skinny batwing or diamond point shape in satin silk or grosgrain silk.
