Designers Mary-Kate and Ashley Olsen are lending their fashion expertise to youngsters by creating outfits for a children's style blog.

The former child stars, who oversee their own high-end labels, have created trendy looks for children models on Ladys & Gents, a webpage started up by the Olsens' stylist pals Estee Stanley and Jenni Kayne.

The actresses both posed in photos for the site with outfits they put together using colourful pieces from J. Crew's kids' collection Crewcuts.
