There's no difficulty wearing bow ties if you tie them right. I love them.
Since this thread started I've been searching in vain for 2 photos I saw somewhere in the Net, in which someone praised the look of the crooked bow tie. I seriously doubt either wearer was trying to look rakish. The cock-eyed bow tie is the bow-tie wearer's worst nightmare. You can try to straighten it for hours, yet it never stays put.
I've experienced the spinning propeller effect myself -- wouldn't you know it was when I was about to walk onstage to deliver a lecture. After repeated re-tyings in front of a mirror, I finally realized that to correct it I had to do each step oppositely until I hit on the problem. I found 2 causes. Just remember that the two ends of the tie have to work in common. So, not to go into detail, this problem can result when you either (a) fold the first fold in the wrong left-to-right direction or (b) loop the second end behind rather than in front of the first fold. In both cases the tie will just dangle and spin as shown in the photos that I regrettably can't find.
Learn from my experience. Never take things for granted, and before going onstage or into public, give the bow a little flip to make sure it's going to stay in place. Then proceed with the confidence that somebody's not going to snap your photo and post it on the Internet to your embarrassment as a daring new flourish in wearing a bow tie crooked.
