Duchess of Cambridge started the official royal duties after celebrating her 36th birthday with a visit to Place2Be. She was wearing a Hobbs London Gianna coat. Taking inspiration from the traditional riding coat, the Gianna is a modern classic. Made in beautiful French navy wool, it is beautifully tailored and has dramatic femininity achieved by the flared skirt and black detailing. The curved collar and pewter buttons add an extra equestrian touch.
