Sienna Miller
Twenty8Twelve

STYLE QUOTIENT
Sienna and her equally stylish sister, Savannah—a graduate of Central Saint Martins school of design—put their heads together to design a line of boho chic clothes called Twenty8Twelve. The collection will reportedly hit Bergdorf Goodman and Neiman Marcus soon, but style-setter Sienna has already created a buzz by wearing pieces to parties and on strolls around the London streets.

FASHION PHILOSOPHY
"I'm really not good at dressing up and being glamorous. I'm fine when I’m just waking up and putting on a pair of jeans," Miller has said.
