Last week Sienna and Savannah Miller’s brand Twenty8Twelve opened a pop-up store in Selfridges. The launch of the designers’ shopping space aims to introduce Miller's spring/summer collection to the customers of the department store. You can find Selfridges’ transformed Hut on the third floor, where a fairground has been recreated. Lucky dip barrels and photo-op boards are a small part of the artistic decoration. The real party, though starts on March, 14th when the girls would come along and meet the lucky hundred, who first made a Twelve8Twenty purchase. And if you want to get hold of more than the signed images that they will be offering, then check out their online exclusive Brea jacket, signed by the designer duo.
