7. Eva Mendes

Actress Eva Mendes has also slowly creeped up the style ladder and really shined in 2010 (being a Calvin Klein jeans model doesn't hurt either!). Eva always has an effortless yet glamorous look about her which I love. She always knows what works for her and prefers to wear prom style dresses with full skirts or sleek gowns that show off her figure along with gorgeous heels (she often wears Sergio Rossis and Brian Atwood). Her go-to designers are Valentino, and Oscar de la Renta and she does full justice to the clothes with her perfect make up and glossy, volumnous hair!
