Blake Lively made her Cannes Film Festival debut for the ‘Grace of Monaco’ premiere, which doubled up as the opening ceremony this evening (May 14). As expected, the actress wore a Gucci Premiere gown, looking absolutely divine donning a two-tone bordeaux silk-chiffon fully pleated gown featuring a geometric neckline, open back, fitted bodice and high side slit showcasing her gold Casadei sandals. Opting for a messy high braided ponytail, the actress completed her look with smouldering eye makeup and the most stunning rose-gold and ruby Lorraine Schwartz diamond vine earrings and bracelet.
