Kate Middleton looks stunning in pale yellow dress as she arrives at the Royal Wedding

Kate Middleton, the Duchess of Cambridge, couldn't possibly miss the Royal Wedding and showed up as beautiful as ever, wearing a light yellow dress.

The mother-of-three, who married Prince William back in 2011, one of the most celebrated and broadcasted weddings in royal wedding history, stepped out of the car with her children, Prince George and Princess Charlotte.

While the young ones played the role of bridesmaid and page boy, and with her husband having accompanied Harry on his way to St. George's Chapel earlier, Middleton was left to fly solo, according to Buckingham Palace.

But even though she wasn't assigned a role at the wedding, the 36-year-old managed to spread her charm, beauty and charisma as she climbed the steps to join the other guests.

At first glance, her dress, an Alexander Mcqueen design, which was completed with a Philip Treacy hat, appeared to be white under the warm Saturday sun, but it was, in fact, a very pale yellow.

This wasn't the Duchess' first time wearing the dress. She wore the create it to both Princess Charlotte's christening and Queen Elizabeth II's birthday party last month, on April 21.

The Royal Wedding marks Middleton's first public appearance ever since she gave birth to Prince Louis on April 23. The royal baby wasn't seen at the ceremony, having stayed at Kensington Palace with a royal nanny.
