Kate Middleton observed Easter Sunday in Sydney along with Prince William and Prince George as the royal family together carried out a few engagements in the Australian city.

The Duchess of Cambridge wore two dresses to mark the day. Earlier in the day, their Royal Highnesses attended an Easter Sunday church service at St. Andrew's Cathedral in Sydney.

Kate opted for a complete regal look to embrace the event by wearing a dove grey Alexander McQueen coat with Jane Taylor Hat.

The 32-year-old Kate looked elegant as she teamed her ensemble with cream high-heeled court shoes while half of her hair had been coiffed under her hat.

Later in the day, the Duchess went completely sporting a relaxed look as she recycled a dull yellow embroidered frock dress from her wardrobe. Kate wore the same dress in 2012 and is believed to have designed it herself.

Kate teamed her knee-length dress with her Russell & Bromley wedges for visiting Sydney's Taronga zoo where a bilby, a rabbit-like marsupial, was named after Prince George. She let her hair loose and blow-dried.

The Duchess looked comfortable in her ensemble as she arrived at the zoo carrying her nine-month-old son in arms, toured the zoo, fed animals and watched a bird show.
