Mary Katrantzou - Mary Katrantzou’s black Ava gown is embellished with vertical multicoloured stripes in tune with the designer’s kaleidoscopic vision. The bandeau silhouette is fitted around the bodice and hips before it extends to a gently flared skirt for a flattering fishtail silhouette. Team it with a fluffy bag and platform heels to complete the high-octane look.
