With the much-anticipated Jimmy Choo collection set to hit H&M stores in just over a month, the budget-friendly chain is giving us something else to be excited about: Sonia Rykiel! A favorite of stars like Rihanna and Gwyneth Paltrow, Rykiel will be the next H&M guest designer for Winter 2009 and Spring 2010. And that’s not all: The fall collection, which will drop in H&M stores worldwide Dec. 5, will also be available in Sonia Rykiel’s major boutiques — a first for H&M. The Sonia Rykiel for H&M spring collection (available Feb. 20) will also include iconic knitwear for women and girls along with playful accessories. Our calendars are marked!
