Festive Cocktail Attire - Winter Wedding

[Showtunes]

I've been invited to a wedding in Colorado this February. The invitation calls for "Festive Cocktail Attire" - There have been posts in the past on this forum about this, however the advice has been lacking to say the least. I've read quite a few great posts on Styleforum so I know there are knowledgeable folks on here.

I thought it may help to put the bride and groom in context before you make suggestions. Both have a great appreciation for clothes. They understand the ins and outs of the manufacturing process, what's quality and what isn't. For instance the groom just walked me through buying a pair of Iron Heart 634s - ( http://tinyurl.com/dzgnzx ) my first pair of Japanese denim. He has also contracted out a beautiful gray custom suit to be made for his wedding that is lined in what looks like purple velvet - accompanied by a very nice pair of cordovan shoes from one of the only two shoemakers left in the United states.

With that context in mind. What suggestions do you have for male guests that would really be an enjoyment to wear on such a special occasion and support the request for festive cocktail attire?

for me, this would be the perfect opportunity to break out my black velvet blazer. the rest is up to you but i'd wear it with white twill french cuffed shirt (sans tie), silver cufflinks, white linen pocket square, gray flannel pants, and well polished black plain toe oxfords.
