Duchess of Cambridge started the official royal duties after celebrating her 36th birthday with a visit to Place2Be. She was wearing 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 a dramatic femininity achieved by the flared skirt and black detailing. The curved collar and pewter buttons add an extra equestrian touch.
