Sienna Miller channelled ladylike chic with an elegant updo at the UNESCO Gala 2010. The star traded in her usually loose centre-parted waves in favour of a high bun for the event in Dusseldorf, Germany.
The classic hairstyle, reminiscent of Audrey Hepburn, was the perfect complement to Sienna's glowing complexion, statement diamond necklace, drop earrings and stunning nude floor-length Stella McCartney gown.
Nobody can switch from bohemian street style to red carpet radiance quite like Sienna.
We love this take on the classic bun. What do you think of Sienna's simple updo?
