kate middleton mulberry dress

Bringing back the Farrah Fawcett feathered 'do was the Duchess of Cambridge last night. Kate was back in the spotlight sporting a new Seventies hairstyle comprising of a heavy fringe, layering and a shade darker than usual. She topped off her new look with an old dress designed by Mulberry.

The young royal attended the opening of the Natural History Museum's Treasure exhibition in the green silk full pleated button up shirt dress. Featuring Mulberry's 'Peace and Love' pattern, balloon sleeves, a Peter Pan collar and waist belt, the dress originally sold for £1,400. She previously wore this dress last November to the launch of the Queen's Diamond Jubilee celebrations at Buckingham Palace.

The Duchess teamed her Kermit-coloured frock with a pair of her favourite black Jimmy Choo 'Cosmic' pumps.

The Treasure exhibition opens to the public this Friday. It spans 7.5 billion years and showcases 22 of Britain's most precious and unique artifacts. Kate was asked to speak at the Gallery after Sir David Attenborough was unwell and absent from the event.

"The Natural History Museum has a very special place in the heart of this nation. William and I are just two of millions of people who have passed through these doors, and marvelled at the spectacular wonders of the natural world, housed in this beautiful gallery," she said during her speech.

"I care passionately about what this museum stands for. Being here tonight, seeing some of nature's finest treasures, reminds me just how precious and awe inspiring the natural world is."
