Catherine introduced the earrings on the right on her tour in Asia. The pearl and diamond earrings were introduced at the 2012 Diamond Jubilee at the Thanksgiving service (her aunt-in-law, Sophie, Countess of Wessex has the same pair). The middle diamond earrings were introduced last year. The silver and diamond drop earrings were introduced at a Olympic Concert at the Royal Albert Hall in May. The Earrings on the very right were introduced at the Olympic Games.
Catherine's first awesome hairstyle was at a Olympic Concert at the Royal Albert Hall in May. The middle picture was at the Royal Order of the Thistle. THe last one was at the Wedding of Prince William's cousin.
The top row on the left was at the Royal tour of Asia, some people hate it but I really liked it. The next is at the Thanksgiving service during the Diamond Jubilee. The top row, on the right was at a Garden party, her first. The bottom row on the left was seen at various events. The hat on the bottom row on the right was during the Trooping of the Colour.
