Kate Middleton Sparkles In Green Mulberry Dress At Buckingham Palace (PHOTOS)

The Duchess is back! Kate Middleton donned her favorite shade of green -- at least, we think it should be her favorite, because she looks great in it -- to greet guests during a media reception at Buckingham Palace tonight in London.

Just days after she hit up the grocery store in a casual sweater and jeans , the Duchess of Cambridge did a 180 and went for straight up glam, in a $2200 silk dress by Mulberry. Thankfully, she also ditched the shopping cart!

The green pleated shirt dress has a "exclusive 'Peace & Love Jacquard' pattern" and a peter pan collar. But Kate didn't stop there; she accessorized with her favorite charm bracelet , a wedding gift from Camilla, Duchess of Cornwall.

We weren't surprised to see the color, because green is one of Kate's signature hues: she famously wore this DVF dress to two different events (*gasp!*).

Although we were focused on Kate's wardrobe, there were other A-list royals in attendance, too. Prince William joined his wife at the event, where 350 members of the media mingled with the family at Buckingham Palace. The Queen was also in attendance, decked out in glamorous green as well to meet with the British press.

We'll add better photos when we get them, but for now, check out a sneak peek of Kate's dress below!
