I love the look of a classic ponytail in casual- or formalwear. It's always in style and suits all types of hair textures. The fun aspect of ponytails is that you can make them high, low, loose, teased, and even leave the lengths curly, wavy, straight, or any way you please. It looks like pretty ponies aren't going anywhere for this season either. Take Rosie Huntington-Whiteley, for example, wearing her hair in a loose, centre-part ponytail backstage at the Michael Kors show yesterday. Michelle Trachtenberg was also spotted at a party in NYC donning a similar, yet slightly more sleek, style. And on the catwalk at the Milly show, the models wore their hair parted in the center in a medium-height pony. What's your favourite ponytail look?
