I think you are missing the point. A jacket is an entire appearance, whereas a tie is a minor thing-it doesn’t add/detract from looking respectable as much as a jacket.
I think you’re wrong. I think a tie adds a lot to the image. On Shabbos, I am makpid to always wear a suit WITH TIE. If I go to a chassunah, I always wear a tie as well.
