Royal ladies in blue!

For their first public appearance as a trio at the Fortnum & Mason department store in London Thursday, Duchess Camilla, Queen Elizabeth II and Kate Middleton showed they were on point in coordinating ensembles.

Duchess Kate chose a blue M Missoni coat dress from the Italian designer's contemporary diffusion line with gray suede Rupert Sanderson "Malone" pumps, Camilla wore a striped crepe coat by Bruce Oldfield and the Queen donned a powder blue outfit by Angela Kelly.

While on their outing, an official part of Queen Elizabeth's Diamond Jubilee celebrating her 50th year on the throne, Kate, 30, Camilla, 64, and Elizabeth, 85, treated themselves to a sugar fix.

Upon arriving at Fortnum & Mason to have tea in the store's new Diamond Jubilee Tea Station, the royal ladies made sure to stop by the candy counter to stock up on their favorite sweets – save for the Queen herself.

Prince William's wife was overheard confessing to the staff at the chocolate counter (which she called "the naughty counter"), "Oh, I love chocolate. Yes. I think most girls like chocolate," while Prince Charles' wife Camilla cooed, "What a treat!" over a bag of jellybeans.

Another royal family member who received a special treat? Will and Kate's new puppy!

"Kate bought some Fortnum & Mason dog biscuits for Lupo," a source tells Us Weekly.
