Back in '90s, I wore a tie clip (a gold bar with a square cut black onyx set with the letter "D" in 14K gold script and a diamond in the D's void) that I received as a grad gift from my parents. But, I stopped wearing it because it was fairly gaudy.I always wear a tie clip. Not because I want to make a statement but because not wearing one allows my tie to flop around, which drives me crazy. For me, a tie clip is all about its function.
However, for the last twenty years or so, I've taken to tucking my tie into my shirt between the second and third button holes. I do this if I'm eating or if I need to keep it from flopping forward if I lean over machinery, a drafting desk, digitizing table, etc.
Some people think it's gauche. I just think of it as practical.
