The Olsen twins have just added a coffee table book to their growing list of “projects”. Influence introduces readers to respected artists, seasoned designers and others who have influenced Mary-Kate and Ashley Olsen over the past decade. Including; Christian Louboutin, Diane von Furstenberg, Lauren Hutton and Karl Lagerfeld Influence has exclusive photos of the girls and loads of other never-before-seen material and interviews from their personal collections.

I sneaked a peek at them on Oprah recently where Ashley described the books subjects’ as "the most interesting, challenging, creative people we know-the ones who helped pave the way for us and our generation." But in fairness, there’s no question that these two have influence themselves. Having built a multi-million dollar business by the time they hit puberty Mary-Kate and Ashley became billionaires by their 21st birthday.

In 2006 they launched a high-end clothing line called The Row (check out the promo video below-gorgeous), followed by a more contemporary line, Elizabeth and James (after their siblings). The twins are considered fashion icons and are highly respected by legendary designers for their bold personal styles. I personally prefer Mary-Kate’s thrown together, sometimes “bag lady” style-she’s fantastic..
