This morning, the Duke and Duchess of Sussex arrived in New Zealand for the final leg of their 16-day overseas tour.
So far the couple have spent time in Australia, Tonga and Fiji, since announcing they are expecting their first child in Spring 2019.
Royal-watchers will have noticed Meghan chose to wear longer sleeves and lighter-coloured clothes in Fiji – and there’s a very important reason why.
Kensington Palace said the couple had sought medical advice and decided to continue with their plans.
As a result, the Duchess chose to wear more covered-up ensembles in Fiji to prevent mosquito bites.
“Wearing long sleeves and baggy clothes will help”

Professor James G Logan, Head of the Department of Disease Control at the London School of Hygiene and Tropical Medicine, told PEOPLE magazine: “Wearing long sleeves and baggy clothes will help.
“Mosquitoes can even bite through jeans so if the clothing is loose it’s much harder for the mosquito to bite.
“Wearing light-coloured clothing can help as these mosquitos are often attracted to dark clothing.
“It also helps you spot them, if you see a dark mosquito on a light piece of clothing.”
During her second day in Fiji, Meghan wore a £1,150 printed wrap dress by Parisian brand Figure.
On her first day, she wore a custom-made white Zimmerman dress, again featuring long sleeves.
Her outfit choices in Fiji have been in contrast to her Australia wardrobe, where she bared her arms in sleeveless and strappy dresses.
Meghan also wore a lot of dark colours during her stay in Australia, including several navy dresses.
After announcing that Meghan and Harry are expecting their first child, Palace officials confirmed that no changes to the tour schedule would be made in light of the Zika threat.
Zika can endanger unborn babies, with pregnant women advised to avoid all travel to areas where cases of the mosquito virus have been reported.
