I don't know. Perhaps. Something is certainly slightly off but I really can't nail it down precisely. First I was going to say it's the shirt as well, then I thought it might be something about the relative width of the tie vs the lapels, then the precise shades of grey being combined and now I just don't know. It's not like any one of these is particularly egregiously wrong, or it would easier to be more definite. I think it might simply be one of those cases where everything is basically fine, but nothing quite sings. (Except the socks, but they're off-key. )
The quickest/simplest fix I can think of would be to just substitute a true-black grenadine (a knit might be too narrow for stitchy) for the charcoal grey tie.
Haven't worn a bow tie in ages. This one is floppy enough to wilt down nicely over the course of the day, naturally narrowing its profile, but here's how it started off. The outfit as a whole has a little too much blue in it, but I tend to do that when I have an early start to the day and so am too sleepy to think when getting ready. In particular, a complementary - instead of matching - hanky would have made a world of difference.
