The Marni for H&M collection hits stores next month, and we can hardly wait! And we’re not alone in our eagerness for the print-centric Italian label’s lower-price collaboration: Felicity Jones, Drew Barrymore, Freida Pinto, and Jessica Chastain were among the celebrities who suited up in Marni for H&M for an all-out Moroccan-themed bash celebrating the line in Los Angeles this weekend. “It’s accessible and affordable,” Barrymore told InStyle.com of the collection. “I love when people bring high end designers to these stores where you can supermarket sweep it and be crazy and not break your bank.” We agree! See how more celebrities styled the line in the gallery, and shop the pieces at H&M stores starting March 8th.
