"Of course, people will say I'm cashing in on Sienna's fame, but this is something we have talked about for years," said Savannah.

The siblings remain adamant they want their work taken seriously because both have the credentials to back it up (Sienna was a model before she switched over to acting, while Savannah is a fashion graduate). "This isn't just for a season or two, we're in it for the long run. We have designed everything," Savannah added.

Twenty8Twelve's first collection, An Anthology Of Rebellion, debuted this month in a double spread for Vogue where according to The Daily Mail items don't come cheap. T-shirts begin at £45 while a pleated coat will set you back £355. [source]
