Brave lady: Sienna Miller shows plenty of cleavage in dangerously low-cut dress at Cannes
CANNES juror Sienna Miller has been turning heads with her glamorous looks during the 68th Film Festival, but the little black dress she wore last night has to be her most daring outfit yet.
Sienna Miller looked sultry at the Swarovski party
The 33-year-old made a very brave choice in the sexy number which featured cleavage-bearing cut-out detail, putting her assets on full display.
Attending Swarovski's glamorous Cannes Film Festival bash on the second evening of the festival, the British actress stole the show in the plunging garment which also featured a large bow across her décolletage.
Sienna cinched in her svelte waist with a riveted belt and polished off her look with strappy stilettos to show off her shapely, tanned legs.
She complemented her gorgeous outfit with a little black clutch, jewelled bracelet and a sparkling pair of Swarovski earrings.

The Cannes judge wore her blonde bob in soft waves with a side-parting and minimal make-up to show off her natural beauty.
American-born Sienna joined a star-studded group at the party, including Jane Seymour and Michelle Rodriguez.
Earlier in the day, the blonde stunner kept her daytime look fresh and summery in a crisp white pinstriped shirt-dress paired with tan suede mules and oversized shades.
Stepping out with a huge smile on her face, the Hollywood actress was on her way to deliberate with the rest of the jury which nominated film would bag this year's Palme d'Or prize.
Sienna's daytime look was chic and casual
Sienna has been wowing the film industry with her impeccable sense of style since she landed in Nice three days ago.
At the photocall on the first day of the iconic film festival, the American Sniper actress oozed old-school glamour in a textured off-the-shoulder Balenciaga design.
The stunning silver creation featured a black studded panel around her midriff which emphasised the curve of her waist.
She continued to stun the following evening as she hit the red carpet for the opening ceremony.
Wearing an asymmetric midnight blue Lanvin ball gown with a dramatic oversized bow detail on her shoulder, the star gracefully posed for the paparazzi at the French event.
