a million ways to look the same...

What to wear?! I'm trying to pack light, but it's 50 degrees and rainy there!
And what does one wear to this kind of wedding?! I've decided not to bring a suit in and effort to add a little flavah since I already know that I'll be the only Asian guy. I know all of these outfits look the same...ish. but that's cuz they kinda are. They are varying combos of 2 different jackets, 2 different sweaters and 2 different ties. 16 different combos in all (but I've spared you with only a few of the looks here. Which one should I go with?!
