For all you naysayers who believe Anna Wintour is incapable of cracking a smile while working, here’s proof that you are absolutely mistaken. Anna Wintour arrived at Burberry’s Spring Summer 2013 show yesterday in London with Mario Testino at her side. While making their way into the tent I captured a special moment between Mario and Anna… a smile. Fashion golddust really. Although if I had a gorgeous snake-skin print suit like that in my wardrobe I’d be cracking a great big smile as well. Or perhaps the smile was purely based on her excitement leading up the big Burberry moment. Who knows and who cares? Looking good, Ms. Wintour.
