We've obviously got a thing for fashion [1], but sometimes it takes a truly standout outfit for us to utter those three little words: we're. in. love.

But this week, between the ruffled gowns, floral decals, and bow embellishments that graced the red carpet [2], we found ourselves speaking them over and over. To put it simply, we're falling fast and definitely want to shout it to the world Buddy the Elf style. ("I'm in love, I'm in love, and I don't care who knows it!")
