A neck tie tells people who you are. There is more than a single way to tying the tie, it all depends on the type of knot you wish to achieve. Neckties have been off the normal wear list for some time as the casual wear came into the office environment. This was great for guys who did not like to have to feel their necks all pulled in. It can be somewhat uncomfortable in the warm weather to have to wear a tie.
It is important to learn what type of tie that needs to be worn for which occasion.
