Sleeper is a brand of ethically crafted, high-quality, multipurpose garments designed to help you feel beautiful — regardless if you are wearing Sleeper on the streets, or in the comfort of your own home.

It was launched in 2014 by two former fashion editors Kate Zubarieva and Asya Varetsa. On one Christmas night, one of the founders had a dream 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 who named Sleeper the brand of the month. Ironically, the brand was one month old at that time.

In February of 2019, brand founders made European Forbes' list of 30 Under 30.

Sleeper's fans include Eva Chen, Katy Perry, Brie Larson, Kourtney Kardashian, Aurora James, Kelly Lynch, Busy Philipps, Chloë Grace Moretz, Zoey Deutch, Dakota and Elle Fanning, Veronika Heilbrunner, and Lena Dunham amongst others.

Today Sleeper garments are available in the USA, UK, France, Australia, Italy, Austria, Germany, Switzerland, Japan, Korea, Norway, Denmark, UAE, Ukraine. The brand's collections are sold in Galeries Lafayette Champs-Élysées, Net-a-Porter, Shopbop, Moda Operandi, Saks Fifth Avenue, Goop, and many other stores around the world.
