Sienna Miller risks flashing her nipples in sheer dress at Berlin Film Festival
The 35-year-old stole the spotlight as she attended the premiere of her film The Lost City of Z with co-stars Robert Pattinson and Charlie Hunnam.
She stunned in a sheer Dior dress which showcased plenty of skin and exposed most of her bare breasts.
The Edge of Love star almost flashed her nipples in the floor-length frock but fortunately they were only just covered up by intricate embroidered flowers.
Her bodice gown was made of see-through fabric which featured a pair of boxer-style briefs underneath.
