Hello everyone!
I'm a newbie to the board, and from Vancouver, BC. Before anyone gets confused, my name here is from a nickname I had in the Army. I was a clerk by trade, and in a Highland Regiment. I worked in the Battalion Orderly Room (the unit office), and like everyone else, wore a kilt in formal uniform. The lads, being the smart-alecks that they are, nicknamed me "the Warrior Princess", and by extension "Xena".
However, I am a bloke! 
Now to my query: I searched for it, and haven't found anything, so I'll take the risk of asking a question that may have already been answered.
I hope most here are somewhat familiar with Jeremy Brett's fantastic portrayal of Sherlock Holmes. In these portrayals, Mr Holmes is portrayed almost exclusively wearing a certain type of tie. It looks like it could be something like a bow-tie tucked under the collar of the shirt, but I doubt it, as that would be rather bulky. I'm hoping some Victorian clothing experts might be able to answer this.
What kind of tie is he wearing? Is it a type of short cravat, just tied in a particular manner? Any help identifying this would be greatly appreciated.
