Sleeper was launched in 2014 by two Ukranian women. One of the founders had a dream on Christmas night about her standing in the middle of a pajama factory. The next winter Sleeper debuted with Winter Collection FW14-15, which was highly regarded by the editor-in-chief of Vogue Italia Franca Sozzani. What sets sleeper apart is the fact they're the only pajamas that can be worn from day to night. They have been worn by the likes of Kendall Jenner, Mira Duma, Veronika Heilbrunner, Emily Ratajkowski, Aurora James, Eleonora Carisi, Leandra Medine, Pandora Sykes and other fashionable women, both at home and at events, always with an indeniable amount of style.
