Sienna Miller was on hand yesterday in London to launch the new electric car from BMWi. It's obviously a green car and this was the reason why she chose bright botanicals to wear for the occasion. One has to assume. One also has to assume that it is a Dolce and Gabbana dress choice. Very nice.

I do actually think that she looks awfully pretty in the dress. I am not sure I would have chosen black sandals to pair with it — a nice metallic would have worked better and come off as lighter, I think. But, all told, she looks very summery and pretty. Nicely played.
