Changing your part is the easiest way to try a new look without the commitment, and lately celebrities have been giving us a reason to experiment. Hilary Duff, Miranda Kerr, and Rosie Huntington-Whiteley have all taken the middle path this week. A center part highlights the face, as it draws the eye directly downward, and it looks beautiful styled with straight or slightly wavy hair. If your natural part is not straight down the center, it's still possible to train it otherwise. Work a mousse, like Aussie Instant Freeze Sculpting Mousse ($4), into your hair prior to blow drying, keeping it away from your roots to avoid weighing them down. This will ensure that your freshly styled strands stay in place. A quick slide of the flat iron on top of your hair will also help accentuate this dramatic part.
