Im sorry that I am not perfect... Anyway the picture wasn't taken by myself, I don't have any that I took myself.
I posted the pic to get some tips and I see that the tie is crap and the reason is - we drove after the chruch with Cars to the restaurant and it was hot so I loosed the tie an opened the upper button and than i forgot to tight tie correctly back.
Maybe the photograph have some better than I Post one of them - this was taken by a guest with his cam
Don't sweat it...there is a very big gap (even bigger than the one between your tie knot and shirt collar ) between looking very nice at an event to the eye of 99% of the population and what will pass as "perfect" here at Style Forum. And I actually like the tie; I would not be too excited about it for most business situations, but for a daytime festive event I think it works. And unless you were at a Park Avenue wedding, I am guessing that you were one of the best-dressed guys there. Spend some time here and the experts will help you with some of the fussier details that will really help you up your game.
