I’ve been to hundreds of weddings, and for some reason I get asked A LOT by grooms and groomsmen if I know how to tie a tie. It’s a good thing that I do. I always do the “single” or “half” Windsor. When I was really young, I did the double, but that was only because it was the first one I was taught. As soon as I found out there was a different option (which looked better, as far as I was concerned), I switched. If I’m shooting your wedding, I’ll tie it for you. Or, if you want to learn how to do it yourself, watch these youtube videos.
