Retailers are preparing for big bucks to be spent on back-to-school clothing. Kohl's is launching its "Inspired" campaign one week after J.C. Penney goes retro for its ads.

Singer Lenny Kravitz and his new song "Love Revolution" will be featured in ads as well as actress and Candie's girl Hayden Panettiere. Avril Lavigne, Plain White T's, The Red Jumpsuit Apparatus and Vanessa Carlton will star in another version of the ads.

Look for 30- and 60-second spots to begin airing July 27.

J.C. Penney is launching a new ad campaign for the back-to-school rush. If you're a fan of the movie The Breakfast Club, these commercials will give you déjà vu.

The "Get that look" ads will feature kids in five new brands coming to J.C. Penney reenacting familiar scenes from the movie. There's even a cover of the movie's most famous song, "Don't You Forget About Me" performed by New Found Glory.

Saatchi & Saatchi, New York, created the campaign that will kick off with a 60-second in theater spot debuting July 18. Commercials will be seen in 93-percent of U.S. movie theaters, with TV, radio, in-store and online ads rolling out over the next seven weeks.

J.C. Penney spent $362 million in advertising last year, not including online ad spending.
