bareMinerals and Cosmopolitan

bareMinerals and Cosmopolitan created National Sleepover Day as a holiday to celebrate spontaneous sleepovers and bareMinerals’ Original and Matte Foundation Broad Spectrum SPF 15’s newest claim – Makeup So Pure You Can Sleep In It™. The two brands are also encouraging women around the country to bare their souls, share their deepest beauty secrets, and express themselves through the hashtag #Sleepinthebare.

In 2017, the Registrar at National Day Calendar declared the day to be observed on May 9th, annually.
