The Plattsburgh knot was invented by Thomas Fink, one of the two co-authors of the mathematical study of neckties titled The 85 Ways to Tie a Tie.
He named it after his hometown of Plattsburgh, NY.
A properly tied Plattsburgh produces a symmetrical, somewhat elongated triangle shape with a small bottom opening.
It is longer and less broad than most knots of comparable bulk, such as the St. Andrew or Cavendish, which makes it a natural pair for narrower point collars.
Smooth-surfaced ties in simple patterns or solid colors do very well in Plattsburgh knots. It is also a useful knot for men with narrower faces in general.
The tying method requires more passing over and under the loop around the wearer’s collar than most necktie knots. Care should be taken to keep these turns as even and symmetrical as possible, pulling all slack out of each one.
Recommended Collars: Point collars
Plattsburgh Knot Step 1
Drape the necktie around your collar with the seam facing outward. The thick end should be hanging on your left side, and the narrow end on your right.
The Plattsburgh is tied with the thick end, and requires several inches of cloth, so make sure that the tip of the thick end starts about four or five inches lower than its desired final position.
Plattsburgh Knot Step 2
Cross the thick end of the tie horizontally under the narrow end from left to right. Flip it upward over the front of the loop around your collar, so that the tip points upward and the seam faces inward.
Plattsburgh Knot Step 3
Tuck the thick end back downward through the loop around your collar on the other side of the narrow end, so that it emerges tip-downward and with the seam facing outward on the left of the narrow end.
Plattsburgh Knot Step 4
Keep wrapping the thick end around the loop around your collar, bringing it back up in front of the loop, still to the left of the narrow end.
At this point the thick end should be pointing tip-upward, with the seam facing inward.
Plattsburgh Knot Step 5
Tuck the thick end back down under the loop around your collar on the other side of the thin end, bringing it out tip-downward and with the seam facing outward, to the right of the narrow end.
Plattsburgh Knot Step 6
Bring the thick end horizontally across the front of the knot from right to left.
You should finish up with the tip of the thick end pointing to your left, and the seam facing inward.
Go ahead and tuck a finger underneath the horizontal band this creates across the front of the tie. You’ll be feeding the necktie through it in a couple steps.
Plattsburgh Knot Step 7
Tuck the thick end up underneath the loop around your collar, bringing the tip up behind the knot.
You should finish this step off with the tip of the thick end pointed upward, seam facing outward.
Plattsburgh Knot Step 8
Flip the tip of the thick end outward and feed it down through the horizontal loop you created in Step 6.
At this point the tip of the thick end should be pointed straight downward, lying on top of the narrow end.
Plattsburgh Knot Step 9
Tug the thick end all the way through the horizontal loop and snug it down firmly. At this point you have the finished shape of the knot completed.
Plattsburgh Knot Step 10
Tighten the necktie by holding the finished knot in one hand and pulling on the narrow end with the other. You may need to adjust the edges of the knot slightly with your fingers to make sure they look symmetrical.
The Plattsburgh is not self-releasing, meaning that it has to be unwound in a reverse of this order to untie it.
