The Keeping Up With The Kardashians star ditched the fitness leggings and trainers and proved her style credentials in a floaty white slip dress which featured a racy satin and lace trim hemline.
Kourtney looked seriously sexy in the thigh-skimming frock that boasted chic three-quarter length sleeves and she turned up the glamour even more with a matching longline jacket that she flung effortlessly over her shoulders.
