The British supermodel - who has fronted cosmetic campaigns for Rimmel London and Dior - prefers to have a fresh, untouched face when she is off duty. She said: "I love make-up when I▓m in the studio but when I`m not working I just want a natural look." Although she favours plain chic over heavy make-up, Kate admits she never leaves home without curling her eyelashes and applying some eyeliner. She explained: "I curl my eyelashes every day. My top tip is never curl them after you`ve put mascara on because your lashes become more fragile. "I also always wear black eyeliner, I like to change my look so will either go for a subtle flick or really build it up for a smoky eye." Along with preferring to keep her make-up at a minimum, the busy mother-of-one also hates to waste time getting expensive beauty treatments, but is particular about the condition of her nails. She said: "I don`t have manicures all the time, but I can▓t bear it if my nails look a mess. I carry a file in my handbag for on-the-go grooming."
