After Lindsay Lohan’s tragic fashion design debut, we should be wary of child actresses who have expanded into the fashion world.

However there is one team of successful actresses showing Lindsay how it should be done and that’s Ashley and Mary Kate Olsen.

The twins, who found fame on various sitcoms when they were young, have built up the Row, a successful fashion line, which includes shoes, accessories and a variety of clothes that we would be proud to be seen in.

They have now announced they are expanding their range into sunglasses.

They have teamed up with luxury eyewear maker Linda Farrow (other collaborations include Dries Van Noten and Sofia Kokosalaki) to create a range of sunnies that will be out for spring 2010.

The styles are said to be classy, chic and more John Lennon than Jackie O. We’re not sure we can wait until next summer to wear them.
