Princess Caroline of Monaco, aka Grace Kelly's daughter, definitely is a timeless beauty! Back in 1976, the Monegasque royal was all about heavy eyeliner, thin brows, and a neutral base. Nowadays, Princess Caroline still dons her signature eyeliner and highlights her gorgeous skin with only a hint of blush. Princess Caroline is also a mother to a very stylish royal: Charlotte Casiraghi. On top of being a regular at Fashion Week, Charlotte is also an ambassador for French fashion house Chanel.
