Slips are so timeless. Think of Botticelli’s Primavera. Or the Empress Josephine’s ethereal gowns. The slip dress of the 20th century first signified the liberation of the flapper, then the glamour of 30s movie stars. After a bit of a rest,* it reappeared in the 80s and 90s, perfected by designers such as Alberta Ferretti, Gianni Versace, and Calvin Klein The line between slip and dress has been permanently blurred by the likes of Kate Moss. Or you, as you choose from Jane’s Vanity’s selection of the very prettiest chemises, slips and gowns.
