Sienna Miller doesn't follow fashion.

The 'Factory Girl' actress insists she is too busy caring for nine-month-old daughter Marlowe - who she has with fiance Tom Sturridge - to pay attention to trends, and thinks her status as a style icon was simply down to being in the ''right place at the right time''.

Sienna told French newspaper supplement Madame Figaro: ''I don't even know what the current trends are! With my daughter, Marlowe, I'm not really able to follow fashion. To be honest, I've never paid much attention to it.

''I was just at the right place at the right time. I love fashion, but I'm not obsessed with it. I like to work on my style but I don't only think about that, even though others might think so.

''I don't wake up in the morning and think, 'Hmm I'm such an icon!' My life is very different: I've got a baby who hardly lets me get two hours sleep each night.''

The 31-year-old actress is famed for her bohemian style, but she admitted nowadays she prefers to look clean and classic in well-fitting clothing.

Sienna said: ''My style has evolved over time. I'm much more classic today. Above everything else, my priority is the cut of the garment, the way it falls on me.''
