Damn this is hard..... well the first one that came to mind was Rive Gauche. I know there are a few other stand out frags in your list but I think this one sits nicely between classy, interesting, GQ but still with a contempoary feel without being too overpowering or perhaps not suiting the occasion in gereral (bearing in mind you cant be TOO bold seeing as though you are at a wedding)
My second choice would be SMW for a fresher take on preceedings but still with enough depth and refinment to put that damn annoying man to shame!!
(sorry I picked 2!!).
