yeah I don't like ties with jeans either. I've tried it before myself but it's just such a formality clash. also, that looks like an orphaned suit jacket, so I can't get behind that either.
individual pieces are nice, but we've got:
1. shirt tucked into jeans
2. sport coat with jeans
3. jeans with no belt
4. undershirt showing (aka poor man's ascot) -- worst offender
5. visible tag on the shoes
ya know, it's one thing to say that Pitti is a circle jerk. I think that's a reasonable observation. But to insist you mean that literally? you're really verging into "doth protest too much" territory.
