Celebrity Label Alert: twenty8twelve

What: Sienna and her sister, Savannah Miller, are designing an fashion line, twenty8twelve, to hit stores this fall.

What the Fashion heads say: Fashion Inc.There are well-cut coats with pleated skirts, lovely blouses done in collaboration with artist David Cooper who designed the print, and fantastic jeans with zips up the back that were the idea of Sienna … I think it’s by far the best “celebrity collection” to date.

What I say: Yet another celebrity joins the ranks of celebrity-designer because, well, they can.  The prices? Not exactly budget: retail looks to range from about $75 for a silk jersey tank to $650 for a leather jacket. In the U.S., you’ll be able to pick up pieces from Neiman Marcus and Bergdorf Goodman.
