For those versed in sartorial rules how formal are knit ties? Are these to be worn with sportcoats only (ie. too informal for suits)?
There are two kinds of knit ties: 1) those made like a "regular" tie, i.e., the shell is folded over a wool lining, and the ends come to a point; and 2) those with no lining, made like "tubes", that have straight edges at the bottoms. Type one are generally made of silk grenadine, and are pretty formal: suit ties, for all intents and purposes. Â Type two are often called "sock ties." Â They may be made of silk, wool, or cashemere, or some blend. Â These are informal ties. Â Â I wouldn't go so far as to say that they should only be worn with odd jackets and never with suits, but I'm tempted too ... In any case, I wouldn't wear them with a smart worsted suit. Â Flannel or tweed, maybe. BTW: there are worsted cashmere ties made like type 1 that go very will with winter suits. Those are not really knits, however.
