Made from 19 Momme silk (that’s a fancy way of saying it’s super soft and super lightweight, by the way), <b><a href="http://www.selfridges.com/cat/olivia-von-halle/" style="text-decoration: none"><font color="black">Olivia Von Halle</font></a></b>’s <b>Mimi robe</b> means that luxury doesn’t need to be confined to the outdoors any longer – who says evening dresses need to have all the fun, right? With a loose silhouette (optimum for lounging) that falls down to just above knee length, slip it on alone or over the co-ordinating pyjamas.
