Alexa Chung already has a Mulberry bag named after her—now she's set her sights on a clothing line with J.Crew's sister brand, Madewell. Alexa Chung for Madewell, the brand's first celebrity collaboration, introduces 20 styles—think dungaree dresses, high-waisted skinny jeans and oversize jackets—that capture Chung's downtown rocker-chic aesthetic. "I was being offered so many collaborations for a long time, but I held off," Chung told WWD. "But Madewell had a more organic approach. Hopefully, the authenticity of this collaboration will be obvious." The collection hits stores and Madewell's upcoming e-commerce site in late August.
