Just recently, I started to wear suits and ties. As for now, I going with the half Windsor.
Whats your favorite knot and which knot is best for what kind of body, height, etc.?

[WestIndianArchie]

Half Windsor.

If I rock a full cutaway, Windsor.

There are some rules about face shape and physique, I don't follow them. Same with skin color

[Mike5055]

All depends on the situation, the shirt collar, and how I'm feeling.

In general though, I prefer the Windsor. For casual, double four-in-hand.

cosign Mike5055's windsor/four-in-hand combo. Unless you have a really narrow face, the windsor is your best bet and a very traditional knot. If the knot is getting too large, try a thinner tie (not necessarily narrower like a skinny tie, but one with thinner fabric and less padding). The four in hand is easier with a casual jacket and looks more in place if being worn with a partially unbuttoned shirt.

[Virtus]

This one. preferably in the same color scheme
60% of the time it works every time

Double Windsor, no dimple, every time.
