Duchess Kate is a vision in pink Alexander McQueen at Princess Eugenie's wedding

Princess Eugenie married longtime love Jack Brooksbank on Friday in a televised event attended by the likes of Naomi Campbell, Kate Moss and Liv Tyler. Of course, the royal family turned out for the highly-anticipated nuptials, which took place in St. George's Chapel in Windsor Castle.

Duchess Kate, who only just returned from maternity leave last week after six months away with Prince Louis, stole the show in a fuchsia pink get-up by one of her favorite designers, Alexander McQueen. She complemented the long-sleeved midi dress with a hat by Philip Treacy and a sophisticated chignon.

The form-fitting silhouette, with its high-waisted belt, showed off the mom-of-three's fit figure, only months after giving birth.

Alexander McQueen has long been a favorite of the Duchess of Cambridge, who has also worn the British label's designs to both Duchess Meghan's May nuptials and sister Pippa's wedding the previous year. The cream get-up she donned to Meghan's has been re-worn a number of times, including at Princess Charlotte's christening.

It's no doubt that the duchess' wedding guest style features some of her best looks ever.
