The only one I like with a suit really is the solid black. The formality of the color is offset by the playfulness of the weave. Although I think that knit ties can go with suits very nicely, I think they are more informal than formal. I think some people might even be insulted if you wear one for an occasion that demands sincerity, as if youre saying Im so carefree I dont care about this meeting.
The grenadine tie, as mentioned before, gives you that texture without the "bounce" of a full blooded knit and no one can question that tie's sincerity for a serious meeting.
the knit tie has definitely not gone the way of the DoDo. I didnt realize the bowtie had. I mean if Tucker Carlson stopped wearing them, that's bad. I guess it's time for me to start wearing them. Although the bowtie looks best on very rugged or gruff men because it softens them up. On most others, it can seem precious. So, if you are Mike Tyson, maybe it works. It's too bad really, everyone should be able to wear a bowtie a couple times a month for variety. But then choices keep getting abridged and it looks like the printed tie is also going the way of the DoDo.
