I was pleased to read this article in the New York Times about the resurgence of the tie in the 18-34 set.
I wear a tie nearly every day. I've never had a job where I've had to wear one. In fact, I've never had a job where anyone else wore one on a regular basis. People don't seem to know what to make of it, but I do get a lot of comments and questions.
We, the tie wearers, have our reasons. One reason I had never considered is "collar wilt" — that is, according the article: its [collar's] gradual collapse (or migration underneath the jacket collar) as the day wears on. Any man who derides the necktie as solely a decorative accessory would do well to remember that it serves an important function in holding a look together.
