The wedding of Crown Princess Victoria of Sweden and Daniel Westling, in Stockholm in 2010, was billed as the biggest since Charles and Diana said "I do," and Charlene was more than ready for her close up. She chose a pale mushroom strapless gown with a diaphanous shawl that had just the hint of bridal about it. And no wonder. Just days later, she and Albert announced their own engagement.
