Samantha Cameron breaks tradition and wears no hat to Prince William and Kate Middleton's Royal Wedding

The Prime Minister's wife decides against any headgear

David and Samantha Cameron arrive at Westminster Abbey

Samantha Cameron stood out at Prince William and Kate Middleton's wedding today - because she wasn't wearing a hat.

David Cameron's wife was one of the few guests not to don any headwear for the big day, with many opting for extravagant, quirky headgear to liven up their outfits.

Princess Beatrice's kooky nude bow-detail fascinator was especially noteworthy and is bound to have got Wills' 22-year-old cousin a lot of attention.

Sam, 40, instead accessorised her fitted teal Burberry dress with a tangerine pashmina, red and gold necklace and chose to wear a small flower clip in her hair.

Within minutes of arriving at Westminster Abbey, the Prime Minister's wife's outfit had sold out on website Net-A-Porter.�
