Pictures of Celebrities at 2012 Comic-Con: Kristen Stewart, Jessica Biel, Michelle Williams & More!

Yesterday marked day three of Comic-Con, and the cast of Breaking Dawn Part 2 has already proven a stylish cast to be reckoned with. The crew kicked off the four-day-long convention on Wednesday night at the Hard Rock Hotel in San Diego — there, Ashley Greene wore a ladylike head-to-toe Oscar de la Renta look, and Nikki Reed opted for an edgier take on cocktail dressing via a gold Etro number. Last night, Kristen Stewart also got in on the fun, donning her signature brand of devil-may-care cool in the form of a Fluxus cropped top, bright BCBG skirt, and Barbara Bui boots. Add to the mix Michelle Williams's playfully printed Giulietta dress and fuchsia-hued Giuseppe Zanotti heels, Nina Dobrev's sparkly gold minidress, and Jessica Biel's slick all-white outfit and neon pink pumps, and we're certainly off to a strong start. Now, see how Comic-Con's fashion frenzy is unfolding — and be sure to check back for even more style updates.
