Sienna Miller In Dolce & Gabbana - BMW i3 Global Reveal Event

Sienna Miller was on hand to help celebrate the BMW i3 global reveal at a party held at Old Billingsgate Market in London on Monday night.

The British actress, who had worn Burberry pretty much exclusively until she was unveiled as the face of the British brand’s Fall 2013 collection, opted for a garden-party-perfect Dolce & Gabbana floral babydoll dress with a bustier top and flared skirt.

Oversized statement jewels, golden tousled tresses, black strappy Charlotte Olympia ‘Sugar High’ sandals and a coral lip colour completed her look.

The earrings are slightly overkill. I am assuming they were added to amp up her day dress to give her look a mid-evening vibe.

You may remember that Lea Seydoux wore this same dress during Cannes Film Festival.

You can buy Sienna’s Dolce & Gabbana dress from Barneys.
