Mary Greenwell is famed for convincing Princess Diana to step away from the blue eyeliner (it clashed with her already sky bright peepers) but that's not to say the makeup icon isn't a fan of blue eye makeup. Mary talks us through how to achieve a modern take on a beauty classic – the blue smokey eye. And no, it's not '80s at all...
