In the world of ties and knots and general formal wear, there are of course, some basic rules that come from common sense itself. Rules like you should simply never wear a shirt and tie with the same pattern, or that the tip of your tie should touch your belt. There are a lot of other lesser-known little rules as well though, which act as useful guidelines to keep your thread-game on point. Here they are. The tip of your tie should always touch your belt line It should be higher than or just about touching your belt line. Anything longer is an immediate negative.
If you're trying and trying but it just isn't working out, you can also just cheat and stick the tie tail inside your shirt!
Usually your jacket should cover this up, but in case it doesn't, then try folding it into the collar. Also, choose a different tie next time, or a shirt with wide spread collars.
