Meghan Markle and Prince Harry are wrapping up their first full day of their Australia tour with a real reception.
Australian Governor-General Peter Cosgrove and his wife, Lady Cosgrove, welcomed the prospective parents during a reception on Tuesday afternoon at Admiralty House. The event was attended by Australians from a wide range of sectors, including charities and community, business and industry, arts and culture, and sports and entertainment.
For the event, Meghan changed things from her previous appearance, opting for a forest green pleated button-down dress shirt by American designer Brandon Maxwell. He completed the look by pulling her hair into a hairstyle and added a couple of naked pumps.
The first Costumes The star previously wore a yellow Maxwell dress in July for a reception in London that celebrated young leaders from across the Commonwealth. It was the first time that Meghan was seen in a bright yellow tone.
It was also the first time she wore without looking at an official event of royalty, as it is rare for real women to show their weapons in public commitments.
During the initial comments of Harry, who started waving to the crowd with a very Australian "Day," the prince shared his excitement of being back in Australia with his new wife, whom he noticed he was visiting for the first time.
"I am very excited to show you this amazing country of yours," he explained in images captured by Nine news from Australia, before recapping your day and upcoming events.
While Harry spoke in the vernacular of the country and told some Australian jokes, Meghan watched from the side and rested both hands on her belly.
"We are both absolutely delighted to be here," he said. "Thank you for the incredibly warm welcome and the opportunity to meet many Australians from all walks of life.
