Sienna Miller

Sienna Miller is an actress - correct.

But she's not a girl who likes to put all her fingers in one pie.

Just call her fashionist Miller.

Yep, having announced last year that she was launching her own fashion label, Twenty8Twelve, she's now ready to show us what she's got (design-wise, that is).

The debut collection is called An Anthology Of Rebellion - how very showbiz - and has been featured in a glossy spread in Vogue.

But how has Sienna managed to find the time to knock all this together?

Well, it seems she hasn't had to do much... Her big sis, Savannah, a graduate of top fashion college Central Saint Martins, is on board.

But Sav ain't too keen on taking all the credit, telling the Daily Mail: "Of course people will say I'm cashing in on Sienna's fame, but this is something we have talked about for years.

"This isn't just for a season or two, we're in it for the long run.

"We have designed everything."

And the celeb designer touch doesn't come cheap... T-shirts start at ￡45, while a pleated coat costs a hefty ￡355.
