So, in spite of being pretty convinced last week that Olivia Palermo and Johannes Huebl had already tied the knot, it was actually this weekend that the world got to see Olivia Palermo's wedding dress. Except, it's not a dress. The happy couple wed this weekend in a park in Bedford, New York (fun fact: where Blake Lively and Ryan Reynolds live) and — shock, horror! — the blushing bride shunned a conventional white wedding dress in favor of an amazing sweater and skirt combo. Turns out that Olivia is following in some pretty famous footsteps, as far as unconventional wedding outfits go... Check out Olivia's dress and three other famous ladies who said no to dresses on their wedding days.
