Saint Laurent's SS19 runway show offers stylish derivations of the house's original Le Smoking, including this showstopping burgundy blazer. It's tailored from plush velvet and conceived with two rows of buttons to give the illusion of a double-breasted front, then completed with vertical darts bodice for an elongating effect. Look closely to spot a silver-tone metal star brooch on the lapel. A ruffled blouse, trousers and platforms will complete a bold party edit.
