Pippa Middleton Ties the Knot in the Most Stunning Wedding Dress

Doesn't this photo just give you the chills? Princess Diana was no doubt smiling on her son as she watched him marry his bride.

Kate and her father make their way to Westminster Abbey. What a proud father he must be!

Outside Westminster Abbey, Kate waved to photographers. How stunning does she look under her Alexander McQueen hand-embroidered veil?

A dutiful Pippa Middleton corralled some very adorable extended family members. Grace Van Custom, the darling girl on the left would go on to make headlines for the hilariously unimpressed expression she wore while Kate and William waved to the adoring crowd from the balcony.

There's no doubt that Kate's wedding dress, which was designed by Sarah Burton, the creative director of Alexander McQueen, was downright spectacular, but Pippa's own white dress garnered quite a bit of attention.

Some other young members of the royal family and/or family friends were invited to take part in the big day. Margarita Armstrong-Jones (the granddaughter of Queen Elizabeth's sister), Tom Pettifer (the blonde boy is Prince William's godson), and William Lowther-Pinkton (the son of Kate and William's secretary).

In addition to her lace veil, Kate accessorized with the royal family's Cartier Halo Scroll tiara. Queen Elizabeth lent the tiara to Kate on her wedding day as her "something borrowed."

The older generations of the royal family were all smiles after Kate and William's nuptials. True to her style, Queen Elizabeth looked jolly in an monochromatic ensemble.

Kate left her wedding in an open carriage, giving the thousands of people gathered outside a glimpse of her stunning face. Kate's flashy earrings were custom made at a little jewelry shop called Robinson Pelham Jewelers. Onlookers were all too far away to notice that the jewels, which were commissioned by her parents, featured a small dangling acorn in the center to pay homage to the Middleton family's coat of arms.

A very regal looking Prince William joined his new bride in their open carriage on the way back to Buckingham Palace. What an absolutely beautiful couple!

Kate and William beamed as they waved to the gathered crowd outside of Buckingham Palace. Thousands of people gathered, forming lines hundreds deep, just to catch a glimpse of the likely future King and Queen of England.

After waving from Buckingham Palace's balcony, Kate and William zoomed off in a sleek Aston Martin DB6 Mark II Volante. How cute are the red, white, and blue ribbons?

We wonder what made Kate make a face! Maybe Prince William gave it a little too much gas? But in a car like that, you can't really blame him.
