Tying a tie is one of those things every guy should know how to do even if it's just for special occasions. But just in case you don't know how, here are easy to follow step by step instructions on how to tie a Windsor Knot (aka Full Windsor). It's a more chunky knot which protrudes out from the shirt versus lying flat like the four-in-hand (the most basic of knots for ties). The Windsor should really be worn exclusively with a spread collar shirt. The knot itself was named after Edward VII, the King of England from 1901 to 1910, who preferred a wide triangular knot.
