Voluminous silhouettes make up a number of looks in Rochas's SS18 collection and this white cotton-blend dress offers an easy way to tap the trend. It's tailored in Italy with a flattering boat neckline and bell sleeves that are gathered at the elbows then falls from a loose waist in fluid folds that will flounce with every step. Pull focus to the V-shaped back with a neat updo before styling it with an elegant box bag.
