According to Vestiny Apparel, Inc., the pop singer and U.S. reality TV star Jessica Simpson is working on an intimate apparel line set to come out this autumn. From the above link:

Launching this Fall 2007, the line consists of lingerie, night/loungewear and day styles. Initially launching in major department and specialty stores nationwide this Fall, the line looks to expand worldwide by Fall of 2008. “The collection is fun, flirty and exactly what I would want to wear,” says Jessica Simpson.

UPDATE FROM The Lingerie Post :

After doing more research, I did find out that Simpson was inspired to create this line after being frustrated with bra shopping herself because of the small selection available for larger cup sizes.

NICE!
