It doesn’t come much more multifaceted than Olivia von Halle's Issa, an unembellished, bias-cut slip dress who looks just as fabulous curled up on the sofa as she does in the centre of the dance floor. This season, she’s revived once more in a moody shade of deep blue and cut from a sumptuous silk-velvet that’s as divine to the touch as it is to behold.
