Alexis Mabille - In a silhouette first seen on the label's Spring/Summer 2019 Couture runway, which debuted the Rainbow Splash collection, this Alexis Mabille dress returns to the spotlight for a new season of red-carpet events. Adorned with an enlarged bow, a feature which takes centre stage throughout the show, it draws the eye to the small of the waist as it reaches from chest to hip.
