Former supermodel Cindy Crawford made an empire from her natural good looks—but having a bit of beauty savvy certainly didn't hurt. "People always talk about plastic surgery and Botox, but I think the right hair color is what keeps a woman looking youthful," Crawford told InStyle. "I like to have a a variety of tones for dimension so hair is bright, not flat." She also mixes and matches her makeup to her own liking. "If you want your base to look real, sometimes you have to combine two colors. I don't want people to say, 'Wow, your makeup looks great!' I'd prefer them to say, 'You look great.'"
