Every fall the celebrity root watch begins; will we be going light or dark this winter?

If the surprisingly stylish cast of Disney’s HSM is to be believed, then this winter will be a dark one. The entire cast and crew is hitting the red carpet as brunettes. Check out Ashley Tisdale’s transformation from All-American cutie to dark and brooding beauty.

Tights have long been a fashion staple of former teen queens the Olsen twins. Now they’ve become the newest obsession for tween up-and-comers like Ali Lohan (whose sister “coincidentally” offers her own line of tights). While the skin-tight styles favored by older celebrities are not exactly teen friendly fare, there are plenty of classic, conservative styles still available. This fall and winter you’ll see them in every shade under the sun plus some new textures and shapes that are sure to get plenty of fashion-conscious teens grounded for life.
