The future Queen consort styled her platinum locks in her trademark blow dry and added a touch of glamour with a stack of pearls round her neck.
In recent times, Camilla's popularity with the British public has steadily grown after years of negative publicity related to her and the Prince of Wales' romantic affair during his marriage to the late Princess Diana.
Royal author Penny Junor previously noted how the public's perception has greatly changed since the 1990s in the Duchess' favour, Yahoo Lifestyle reports.
This positive image is in part thanks to the many royal roles Camilla has taken on since her 2005 royal wedding to the Queen's son at Windsor Guildhall.
Today, the Duchess is patron or president of more than 90 charities and social organisations.
Charles and Camilla's responsibilities are increasing with every passing week, as reports say Queen Elizabeth II is preparing to 'give up the throne' to her heir in the next two years by invoking the 1937 Regency Act.
‘There is talk that when she reaches 95 in a couple of years she may slow down and possibly the Regency Act will be brought in,’ royal expert Phil Dampier told Yahoo’s The Royal Box.
The Act allows a reigning monarch to relinquish power if they feel they are unable to fully perform their duties.
‘She will still be Queen but Prince Charles will, in fact, take over most of the duties,’ Dampier explains.
‘He is starting to do that already, being at the state opening in Parliament and the Commonwealth conference. He is starting to take over a lot of the duties and doing the investitures.’
