Move over, ballgowns – this season it's all about the jumpsuit, making Galvan's Calypso style a winning evening choice. The svelte design is crafted from matte crêpe in purist white, and it's flatteringly cut with a nipped waist and slim legs that flare out from the knees. It's finished with a hand-woven fishnet halterneck that dangles down the back with a tassel trim.
