Meghan Markle, 37, and Prince Harry, 35, ended the day by stepping out for a reception hosted by the British Ambassador to Morocco, Thomas Reilly, and his wife at the British Residence in Rabat.
The royal mum-to-be looked regal in a bespoke dress by Dior featuring draped sleeves.
After wearing her hair loose earlier in the day, Meghan pulled back her locks into a low bun, showing off her Birks Snowflake Snowstorm diamond earrings.
The reception follows a busy day for the couple, which included a visit a boarding house for young girls, where Meghan participated in a henna ceremony.
“It’s for when we have a big party,” Khadeja Oukattou, a housemother at the boarding house, says.
“Now she is pregnant we do the henna to keep her happy with with the baby. For good luck.”
They also stopped by a school and watched the students play football.
Meghan sported a casual look for the day out, wearing a collarless navy blazer from Alice + Olivia over a fitted black top, black pants and her go-to black velvet Birdies flats.
Kensington Palace said the purpose of the trip is to visit projects which aim to strengthen the role of women in society, as well as programmes tackling mental health challenges.
Both are themes close to the hearts of the royal couple.
“(They) will be shown first hand the transformational impact of community-based programmes and Morocco’s changing social attitudes towards women,” a source said.
On Sunday the pair will visit a school in the Atlas mountains aimed at promoting girls’ education in rural communities.
The prince will give the school’s founder, Michael McHugo, an MBE, a royal award, for charitable work.
Harry married the former Hollywood star Meghan last May.
Since then, the couple have become media favourites at home and abroad.
The North African trip is expected to be the last one abroad for Meghan before their baby is born in the spring.
“It’s been a busy day”
The couple arrived in Morocco for their three-day tour on Saturday, where they were greeted by the British Ambassador to Morocco, Thomas Reilly, and his wife, Alix.
Meghan made a stylish entrance in a glamorous red Valentino dress with an elegant embroidered cape detail.
The Duke and Duchess of Sussex have decided to stay on privately for an extra night at the end of the visit, returning on Tuesday to London.
It was originally going to be on Monday afternoon.
