It was definitely a Duchess Catherine Weekend this weekend...
First Dazzling at the Queen’s Trooping of the Colour on Saturday AM in a black and white look: Jacket McQueen and Phillip Treacy Fascinator.
Then Saturday PM she arrived at a friends wedding with her sister in tow. Wearing the mornings fascinator with a dress i believe its Zara (she has worn before) and Anya Hindmarch clutch.
On Sunday Kate attended a special ceremony for new Grandfather-in-law. Again in a previously used outfit. The Zara dress from the day after the wedding and Jane Troughton jacket (worn before) and Jane Corbet hat.
