The Queen looked absolutely lovely in a powder blue coat with a floral dress underneath. Her coat perfectly matched the gorgeous hat, as she carried a black handbag and an umbrella.

Canadians might recognize the brooch Her Majesty was wearing – it’s the Sapphire Jubilee Snowflake Brooch!
When the Queen visited Canada House in London to mark the 150th anniversary of Canadian Confederation in 2017, former Governor-General David Johnston gave the pin to her to celebrate her 65th anniversary on the throne. The gorgeous brooch features diamonds and several sapphires from Baffin Island.

For the sunny day at Buckingham Palace, the Duchess of Cambridge looked no further than her favourite designer, Alexander McQueen, for the beautiful powder pink number. She paired the double-breasted dress with a matching fascinator and a pair of beige suede pumps.
