Slip's silk pillowcases and sleep masks are beloved by beauty editors all over the world because, not only do the look chic, they also help reduce friction while you sleep, keeping your hair from getting frizzy and your skin getting pulled and creased while you sleep. For Fall, the brand has added a new pink marble print to the range. Use the Slip Pink Marble Pillowcase (£85) at home, or bring it with you whenever you travel to pull over the hotel pillows.
