2011 was the year of the little white dress, clean lines, and silk sheaths. Celebrity fashionistas like Rachel McAdams and Malin Åkerman, were really on trend this year, and paved the way for the simple beauty of a well-tailored and elegant dress. New to the A-List scene is model, Rosie Huntington-Whiteley, who stunned in a midnight blue, silk Burberry gown, which is one look we will forever remember. And of course we have to give a nod to the newest fashionable royal, Kate Middleton, who awed us in her blush pink, Jenny Packham dress, truly befitting of a princess. We can't wait to see what 2012 will bring for these trendsetters!
