Catherine, Duchess of Cambridge In Stella McCartney - Fairbairn Airport

After a busy day, Catherine, Duchess of Cambridge, Prince William, Duke of Cambridge and their son Prince George of Cambridge arrived at Fairbairn Airport on Sunday (April 20) in Canberra, Australia.

In what was her third outfit of the day, the Duchess wore a bright-blue Stella McCartney ‘Ridley’ dress which you may instantly remember as the same dress Catherine wore while opening the ‘Road to 2012: Aiming High’ exhibition for the 2012 Olympic games.

On this occasion she ditched the OTT necklace, for a more modest pendant, styling her look with her much worn navy pumps.

I love how the family are all wearing blue here.
