Style Superstar: Emma Roberts Is A Pretty Witch In White

With the "American Horror Story: Coven" premiere bringing out so many pretty young things for its red carpet, it's no surprise that our Style Superstar is one of the show's sassy witches. The entire cast brought it in such a big way, it was hard to pick just one of the students at Miss Robichaux's to award this week's honors to—but when pressed, it was the woman in white who took it home.

Emma Roberts was a show-stopper in this white cutout Cushnie Et Ochs dress that showed off a peek of her lovely abs. With a glittering triangular clasp on the bodice, super-smokey eyes and her hair swept in a wave over one shoulder, her look was magic indeed...so magic, in fact, that we won't even get after her for sporting white pumps in cold weather.

Also out and about this week: Mischa Barton, who went for a flirty look at the premiere of "I Will Follow You Into the Dark." But her all-black ensemble with flouncy skirt and peep-toe pumps just didn't come together: too transparent on top, not quite fitting below and without any accessories to punch it up. Mischa looks great when she really nails a look, but this one is a sad, dull miss.
