Sleeper was launched in 2014 by two former editors Kate Zubarieva and Asya Varetsa. One of the founders had a dream on Christmas night about her standing in the middle of a pajamas 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, who named Sleeper the brand of the month.
