Attire: Formal Black Tie - nothing is too fancy or flashy or off limits (I mean, don't make it weird by wearing white) Be creative. Seriously, try to upstage the bride and wear what you never thought you'd have the occasion to! Ladies, encouraged to avoid black and dark colours - think fresh and fancy island vibe, embrace pattern prints & texture. Tuxedos for men, prefer no white dinner jackets, but encouraged to be creative. Keep in mind December weather is a very reasonable temperature that drops in the evening.
