Sienna Miller's Stunning £46 Topshop Dress

Fancy a slice of Sienna Miller style? Easy. Just snap up this gorgeous lily-print navy dress from Topshop, and team with opaque black tights, a faux fur cream jacket (from Isabel Marant), and black ankle boots, et voila! You're Sienna-ready.

The actress was snapped in the cool minidress as she left the Theatre Royal Haymarket after an evening of performing in Flare Path.

We think a slick of popping red lippie would finish the look off to perfection.

But you've got to be quick - there's only size 6 and 8 currently left in stock!
