The Duke and Duchess of Cambridge joined the royal family at Windsor today to celebrate Prince Philip's 90th birthday at a church service. More than 750 guests attended the service in Windsor Castle's St George's Chapel conducted by the Dean of Windsor. Kate looked beautiful in a periwinkle purple coat, which she first wore back in August 2009 to a friend's wedding. Kate also appears to be wearing the Zara dress she wore the day after her wedding. (Thanks to poster below :)) Kate's cream heels are LK Bennett. She previously wore them to the derby. Yesterday we saw Kate wearing a dress from 2007 to Sam Waley-Cohens wedding. Kate is certainly thrifty! Today she teamed her coat with a purple dress and hat with her hair worn mostly down. William and Kate appeared to be enjoying the service!
