I wanted to add to the discussion of the collar pins. I've ordered two different sets, ones that somerset fox linked to and ones that I linked to. Here they are side by side on a collar:
They are both the wrong size. I took several different screen shots of the collar pin from the show and took measurements of the pin on those. I compared that to the digital measurement of the collar and compared that to the measurements of my real-life collar. From that I've determined that the pin should be 3/4" (12/16") or 13/16". The pin on the left is 1.25" and the one on the right is about 5/8". I have not been able to source a eagle lapel pin that is the correct size.
Personally, I prefer the pin on the left even though it is a little over sized and that's what I'm going to use. Eventually, though, I hope I can find at least some 1" pins...
