This has been the summer of the It dress, and although ankle boots and chunky jumpers are taking over new-in sections, our appetite for pretty summer dresses hasn't quite settled down. This month, a new It dress has emerged, and it indulges the lazy part of our personalities, as it's technically a nightie. Sleeper's linen maxi dress has pretty buttons down the front, puffy short sleeves and looks like something straight out of a Victorian nursery tale. The brand has updated the traditional white nightdress with bold colours and pretty prints. We're especially taken by the dusty-pink version. The Instagram crowd proves that this nightie is the perfect beach cover-up or throw-on weekend dress for those days when you can't waste any time deciding what to wear.
