Factory Girl actress Sienna Miller wants to take her fashion career to the next level by becoming a couture designer.

The 32-year-old fashionista may have stepped down as co-creative director of her clothing line Twenty8Twelve in 2012, but it looks like Sienna wants to stay in industry.

Speaking to Nylon magazine, Miller said: ''We were designing a really big collection in the end ... I think maybe I'd be more fulfilled being a couturier or something, or doing 10 amazing pieces a season.''

Sienna further stated that she struggles to take photos of herself, adding:  "I'm not very good at the selfie face. I can do it for, like, three seconds and then I crack up."
