The collection, which will be under the Jessica Simpson Collection umbrella, will feature both activewear and sportswear.

Jessica tells Women's Wear Daily:

    "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."
