LONDON--Twenty8Twelve's head designer, Elsa Elphick, is probably absolutely sick of people asking her about Savannah and Sienna Miller leaving the brand. They held a presentation over the weekend to showcase the new collection and a fashion film called "Faceless Featured Future." Faceless future, indeed--at least a famous faceless future. So let's get that part out of the way first. I asked Elphick what has changed since the Miller sisters left, and she told me, "For us it hasn't massively changed." Hmm. So how much involvement did they actually have? Elphick assured me that she worked very closely with Savannah, but that now she would be making design decisions rather than have them made for her. When I asked if the Millers leaving would hurt the image of the brand, a member of Twenty8Twelve's team jumped in.
