Stella McCartney and Diane von Furstenberg are not the only designers collaborating with affordable retail brands for children's wear: singer Gwen Stefani, who also designs clothes under the L.A.M.B. label, has teamed up with US budget store Target.

As part of a collection scheduled to launch this fall, American fans of her fashions will be able to shop clothes for both boys and girls, priced from $3.99, making for a budget-conscious alternative to the newly announced kid offerings by the likes of Lanvin.

"I've always wanted to do a cool children's fashion line inspired by the supercute and playful kid's clothing you find in Japan," Stefani told Women's Wear Daily. "The whole idea is about being creative, expressing your own individuality and having fun getting dressed."

The collection will be named Harakuju Mini after the singer's Harajuku Lovers that has already released several fragrances.
