New York, July 10, 2007 – The summery dress that actress Sienna Miller wore upon arriving at the David Letterman studios in Manhattan on Tuesday was, according to her publicist Leslie Sloane Zelnick, from Miller’s own line of clothing called “Twenty8/Twelve”. The line has not yet launched, but Miller has been wearing it around London, where she is often photographed.

A fashion icon, Miller developed the line of clothing with her sister, Savannah Miller, who is reportedly a trained designer.

Miller had changed into black Calvin Klein by the time she exited the studio. She is in New York to promote her upcoming film, Interview.
