The Duke and Duchess of Cambridge paid a visit to Norway’s royal family.
The royal couple had a private lunch with Crown Prince Haakon and Princess Mette-Marit.
However media outlets have been focusing on why the Duchess kept her coat on during the meal.
According to OK! magazine, royal tradition says that if a female member of the royal family removes her coat in public would be deemed "unladylike.
Other royal style rules include no bright coloured nail polish and messy hair.
