The ‘Factory Girl’ actress - who has launched a clothing line, “Twenty8Twelve”- insists she doesn’t choose outfits to please anyone but herself.

She told Hello magazine, “I dress for myself and I don’t care what people think. It’s dangerous when you start dressing for effect, or for the photographers. Where’s the fun in that?”

Sienna, 25, also revealed she doesn’t want everyone to wear her new clothes range.

Despite the financial rewards she would gain, the Hollywood star insists it would be boring if everyone looked the same, and claims she hated it when everyone copied her boho look a couple of years ago.
