This has been the year of the It dress, and although ankle boots and chunky jumpers are taking over stores now, our appetite for pretty dresses hasn't quite settled down. Recently, 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 aback 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.
