Jill chose this blue silk gown for the Inaugural Ball in 2013, completing her homage to the "red and blue" colours of the US flag. The look was created by American fashion designer Vera Wang, who is of Chinese descent. "What a joy, honour and privilege to have dressed Dr Jill Biden for tonight's Inauguration. A beautiful, spirited, accomplished woman!" Wang famously posted on Twitter. Image Source: Getty / Chip Somodevilla
