There was truly no shortage of influential style this year — whether high end or high street, celebrities gave us tons of inspiration in 2011, giving us new ways of thinking about fashion. J.Crew creative director Jenna Lyons provided a fresh, out-of-the-box philosophy on layering and print mixing that couldn't be ignored, while superstylist Rachel Zoe proved that she can move seamlessly from dressing A-list celebrities to dressing us regular fashion folk. Kate Bosworth and Alexa Chung both brought their own brand of effortless cool-girl style, putting a no-fuss spin on even the dressiest of looks. Lastly, we can't possibly forget the Duchess herself: Kate Middleton's polished personal style made just as many waves as her lavish wedding did — she gave royalty a new, more attainable image, wearing affordable pieces from Zara and H&M and putting smaller brands like Issa on the map.
