Meghan Markle chose a classy blue gown that anyone can afford to copy

Before leaving Tonga for Sydney on Friday, Prince Harry and his wife Duchess Meghan visited Tupou College. It is the oldest secondary school in the Pacific.

Harry and Meghan were there for the unveiling of the Queen's Commonwealth Canopy. For this event, both Royals changed clothes again.

Duchess Meghan ditched her green-and-white Martin Grant dress and wore the American designed Veronica Beard shirtdress in blue. She matched her outfit perfectly with a pair of blue suede heels.

They dedicated two forest reserves at the school's on-site forest to the Queen's Commonwealth Canopy. The project sees countries of the Commonwealth designate areas of indigenous forest to be preserved in perpetuity.

The Tupou College Boys Choir performed traditional Tongan music to commemorate the event. Meghan was in hysterics as the choir sang about mosquitoes.

Prince Harry gave a speech saying:

"Tonga is leading by example and understands deeply the impact of environmental changes because they directly affect these islands. Planting trees and conserving forests helps us in so many ways.”

He added:

"It is a simple but effective way to restore and repair our environment, clean the air, protect habitat and enhance our health and wellbeing. We are so very grateful to you for this contribution of the Toloa Forest Reserve and the Eua National Park Forest Reserve."

The visit featured hymns which Harry appeared to sing along to. He was then taken on a tour of the forest while the school's band and students continued to sing.

Before leaving Tonga, the Duke and Duchess were driven to the Royal Palace for an audience with King Tupou VI and his wife Queen Nanasipau'u.

Meghan stuck to her blue dress while Harry changed into a suit. The couple spent around 15 minutes with the King and Queen.

They signed a visitor's book and posed outside with the King and Queen for photographers. While saying goodbye, Meghan was seen curtsying to the Queen.

Before going to the college, the Royal couple had started their day off by going to Tonga’s St George Building to meet with Tonga’s Prime Minister Akilisi Pohiva, his deputy Semisi Lafu Kioa Sika and other cabinet members.

Their meeting lasted for about 10 minutes.
