Jessica Simpson to design line with Ashlee Simpson for "tweens"

Jessica Simpson has announced plans to partner with sister Ashlee Simpson to design a line of clothing for "tweens." The line, which will be a part of the Jessica Simpson Collection, will include denim, knit tops, tees, outerwear, footwear and sportswear.

"Creating a tween apparel collection was a natural extension for the brand. I'm excited to bring my sister, Ashlee, along as co-creative director of this division, because she brings a savvy rocker edge that defines today's tweens," said Jessica.

"My goal as co-creative director will be to design clothes that will help inspire young girls to express their personalities and creativity through fashion," added Ashlee.
