Jessica Simpson may have just given birth to her first child with fiancé Eric Johnson on May 1, but the savvy businesswoman isn't taking a moment's rest: Simpson has paired with Destination Maternity to launch a maternity clothing line.

I'm so excited to partner with Destination Maternity to design a collection of fashionable styles that make you look and feel great, Simpson said.

A preview of the collection debuted online Monday morning, showcasing comfortable pieces -- maxi dresses, leggings, printed tops and blazers --  that have a 1970s vintage feel.

You want to wear clothes that are flattering to your baby bump; you want to show off your bump, she continued.

Jessica Simpson Maternity is a partnership with Destination maternity and her nearly billion dollar clothing empire. The line, which will be available in stores this fall, will be sold in Macys, Motherhood Maternity and Destination Maternity and the pieces will range in price from $36 to $100.

According to a press release announcing the launch, The collection is aimed at the modern mom-to-be who wants to maintain her fashion edge throughout her pregnancy.

Simpson has also reportedly sold the rights to the first pictures of her daughter, Maxwell Drew, to People Magazine for $850,000.
