Olsens launch new book 'Influence' in New York City

Team Olsen combined powers yesterday for the New York launch of their style book Influence (you can hear them talk about the book with Oprah Below).

Mary-Kate (in black) and Ashley (in red)... (well, I think that's how it is anyway... just when I thought I had figured out who was who, they go and match their hair up to make things really tricky!) looked fittingly style-worthy in their respective get-ups.

But who had the edge?

Besides discussing what they eat for breakfast *snore* the Olsen twins' interview with Oprah was actually filled with some pretty interesting stuff. In this clip, Mary-Kate and Ashley discuss their new style book, Influence, and what it was like to interview Karl Lagerfeld the day before his runway show.
