Fashion Flashback: See Every H&M Designer Collaboration Since It All Began

To keep momentum for the popular French designer going, H&M released two back-to-back collections. The first, a lineup of lingerie and nightwear, capitalized on the underwear as outerwear trend. This was also the first time in H&M's collaboration history that the pieces — ranging from $12 thongs and $30 bras to $115 chiffon kimonos and black velour PJs — could also be purchased at stand-alone Sonia Rykiel boutiques.
