Something old, something new, something green, love the 'do!

Kate Middleton dazzled at the Tuesday, Nov. 27, opening of the National History Museum's Treasures Gallery in London, but it wasn't just her gorgeous emerald-colored frock that had people buzzing -- it was her fresh, face-framing hairstyle!

The Duchess of Cambridge, 30, debuted a new cut at the event, with shorter, side-swept layers that skimmed her enviable cheekbones. The rest of her long brunette tresses were curled in loose, shiny waves.

Fashion-wise, Middleton proved once again that she's just like Us by recycling the bright green Mulberry dress she donned for a media reception at Buckingham Palace almost exactly one year ago. The pleated frock has a "Peace & Love Jacquard" pattern, with gold buttons, a Peter Pan collar, and a skinny belt.

Her husband, Prince William**, was not in attendance at the event, which showcased the Treasures collection of 22 special objects, from a 147-million-year-old limestone fossil to the world's most expensive book, John James Audubon's Birds of America.
