On Tuesday, the Duchess of Edinburgh was spotted with Amina Priscille Longoh, the Minister of State for Women and Child Protection for Chad during her solo visit.
Duchess Sophie, 59, was seen wearing an unexpected lime green dress - the 'Brooke' style from Amanda Ross x Soler London. The royal made a subtle tweak to the satin number, swapping the crew neck for a flattering V-shaped style.
Prince Edward's wife also changed the blue waistband for a metallic belt with a chunky reflective buckle.
Translated to English, the Chadian politician penned: "I had the pleasure of sharing a Chadian coffee this morning with Her Royal Highness, Sophie the Duchess of Edinburgh who is staying in Chad.
"We discussed her commitment to women's rights and children's education, especially in times of crisis," she continued. "She wanted to pay tribute to Chad in coordinating the response to refugees and especially the hospitality and resilience of the host communities."
