P.S.....if you are talking about what
I think you are (and a look at the website
will tell you) you definately do NOT tuck it
into your waistcoat. That's a regular cravat,
more commonly called simply a "tie" LOL....
A version of this cravat was worn by the romans
and, I seem to remember, by Russell Crowe and others in "Master and Commander"...........
