Meghan Markle carried out her final royal engagement yesterday while attending the Commonwealth Day service at Westminster Abbey with her husband Prince Harry, and she saved one of her best looks for last. 

Since returning to the UK to carry out her final duties, Meghan has turned heads again and again, dazzling in a series of brilliantly bright outfits, including a red, blue and white trio of looks.

Yesterday's, however, was perhaps one of her most jaw-dropping, an emerald green monochrome outfit that summed up everything Meghan brought to royal fashion. 

Arriving before Prince William and Kate Middleton, in accordance with preference, Meghan looked radiant in the green Emilia Wickstead dress, featuring a high collar, long sleeves and dramatic draped cape detail around the neck.

The look was pulled together with a matching hat by William Chambers, a deep green satin-top handbag by Gabriela Hearst, Birks 'Snowstorm' earrings and her favourite nude Aquazzura heels. 

Harry matched his outfit to his wife's for the special occasion, wearing a soft navy blue suit with a pale green tie and a vivid emerald green lined blazer. It's the latest coordination from the couple, who have matched their outfits impeccably for their last few engagements, in possible sign of solidarity. 

The Commonwealth Day service was a family affair, with the Cambridges and Sussexes meeting for the first time in public since the Remembrance Day service.

Kate looked glamorous as always, re-wearing a burgundy coat by Catherine Walker accented with red velvet cuffs and collar, with a matching hat topped with light pink flowers by Sally-Ann Provan and a pair of ruby red Gianvito Rossi court shoes.

We also particularly loved her delicate drop earrings featuring one brilliant ruby dangling from her ears. Prince William also coordinated with his wife, donning a smart burgundy tie for the occasion.
