Hello. I'm Charles Brunold from New York. I'm going to teach you how to do a Pratt Knot today. The Pratt Knot is also called a Shelby Knot. I have the particularity to start upside down. So, you start with the tie the wide end about 12" below the left of the narrow end. Here I'm going in with a pretty skinny tie. So, the knot we are going to obtain is not as wide and fluffy as the one you would obtain if you did it with a wider tie, obviously.
So, this is how you proceed. Starting with the tie upside down, you go the wide end underneath the narrow end, over, inside and out, over the narrow end. Just pull it in front with the wide end in front. Bring it underneath and just slide it inside the loop. There you go. You've got a Pratt Knot. Just adjust the knot. Tighten it and adjust your collar.
So, this knot, the Pratt Knot is very suitable for any type of dress shirt, any type of collars. But, here I like to wear it with like a skinny tie and a widespread collar like this one. Seeing the result is fantastic. So, this is how you tie the Pratt Knot.
