Doutzen Kroes knows how to style her hair so that it looks glamorous but not overstyled. Take this look, for example. Her outfit and makeup are striking, especially those piercing cat-eyes. But her hair is soft and romantic with her honey highlights loosely pulled back away from her face. An updo is really the only option with this kind of neckline, and here Doutzen's hair acts as a pretty contrast to the high impact effect on the rest of her look. It's also a style that can last through any A-lister red carpet party with only a small spritz of spray to give a light hold. Perfect for both versatility and practicality!
