Jessica Simpson: creating clothes with sister Ashlee. (Mario Anzuoni/Reuters)

Jessica Simpson — the same woman whose clothing and accessory line reportedly made $750 million last year — has invited Ashlee Simpson to get in on the act.

The elder Simpson has asked her actress-singer sister to help her design a line of clothes for tweens because she says Ashlee “brings a savvy rocker edge that defines today’s tweens.”

A report in the New York Daily News says the clothes will be available at Lord & Taylor’s and Macy’s, presumably just in time for back-to-school shopping.

At first blush, the notion of Jessica and Ashlee Simpson essentially dressing the young girls of America might sound alarming. But honestly, Jessica Simpson — recently named Us Weekly’s Style Icon of the Year — has distinguished herself as having a pretty good (and often classy) eye for what consumers want to wear, even if she has occasionally made some missteps on the red carpet.

In fact, in a true confessions moment, Sarah Anne Hughes and I just revealed to each other that, yes, we like a number of the styles available via Jessica Simpson’s shoe line.

There. I said it, and I feel better.
