Suki Waterhouse is like a chameleon with her style.

The British model - who is dating Bradley Cooper - compares her fashion choices to the lizards, some species of which have the ability to change skin colour based on their psychological condition, because she chooses her clothing to reflect her mood.

She said: ''I'm a real chameleon with my style and I use outfits to express myself and the character I want to be that day.''

The 21-year-old beauty is the face of Sass & Bide and recently shot the brand's autumn/winter 2013 digital campaign in New York City, and she was delighted the company allowed her to display her own originality in the shoot.

She added to the Daily Telegraph newspaper: ''It's a lovely thing when brands allow you to bring your own creative flair. It made the whole experience even more enjoyable and I loved the Sass & Bide collection so I was spoilt for choice.''

Heidi Middleton, one half of the brand's creative duo alongside Sarah-Jane Clarke, admits Suki was an easy choice for the role because the pair fell in love with her style and personality straight away.

She explained: ''Suki embodies the spirit of the brand. She has a curious mind and looks at the world in an original way - we felt an instant connection to her.

''We wanted Suki's creativity to shine. In the behind-the-scenes images we've provided an insight into who Suki is as an artist, a photographer, a model. That was interesting to us.''
