- Collar is too wide and too fat, so too is the knot. Tighten it up. Use an Oxford collar if need be (and it tends to). You should NEVER see the shirt between the tie and the collar. And the tips of the collar should be visible, not under the suit coat. In general, it seem like the suit coat collar is riding up, not laying flat.
- Kerchief in the suit always matches the tie, NEVER the shirt. Better yet drop it.
- Solid color tie is great, are you serving dinner or just seating people? Get something with color, and some sort of pattern or else you look like a service worker. Or get a colored shirt, otherwise people are going to be asking you to bus the table. So...the gray tie would be good with a dark suit and dark shirt (kinda Guido, still), but find some color. Use the poka dots if you need to, but buying a nice colorful one would be better.
- It looks like the suit is wearing you, not vice-versa.
