Sienna Miller hates her style being described as "boho".

The'Factory Girl' actress - who is expecting her first child with partner Tom Sturridge - admits she previously went through a "hippie" phase of dressing and while she is now a fan of more tailored clothes, she thinks her laid-back attitude is still reflected in her wardrobe.

She said: "I hate the word boho so much now. I suppose I am inherently bohemian in terms of the way I am as a person, and I definitely went through a hippie phase with my style. But I think it's really more about the way my personality is, than the way I dress. Now that I'm a bit older I do appreciate tailoring much more than I used to, but my personality is still very laid-back. Even when I put on a power suit I still look like a hippie, so I suppose it's true."

In February, Sienna and her sister Savannah announced they were stepping down from their label Twenty8Twelve and the actress revealed her sibling is already working hard on a new venture.

She told Vogue.co.uk: "My sister is an amazing designer - she's working on her new label at the moment.

"In fact she's designing in my attic as we speak. I just can't wait to wear all of the pieces."
