Salma Hayek has hailed Sarah Burton as "mind-blowingly extraordinary".

The Mexican actress believes the designer - who is creative director of Alexander McQueen - has done an excellent job at the label and has been impressed by her collection at London Fashion Week, which included a dress seemingly made out of an array of flowers.

She said: "The show was truly sensational - really, really amazing. Sarah Burton set the bar really high - it makes me nervous it is so good. It was so mind-blowingly extraordinary - every single piece - and very wearable."

Also on the catwalk at the show was clothing inspired by a pack of Crayola crayons, with flowers, capes and jumpsuits making an appearance.

Sarah came to worldwide fame after she created the dress worn by Britain's Duchess Catherine at her marriage to Prince William at London's Westminster Abbey on April 29.

She took over the label after the suicide of boss Alexander McQueen in 2010 just days after his mother died.
