Archie wears white bobble hat that is a copy of one worn by baby Prince Harry in 1985

Baby Archie was cradled in the arms of his mother, Meghan Markle, as they stepped off the plane, with Prince Harry,34, walking in front. The tot wore a blue romper suit, which he accessorised with the hat. The item is an exact match of one worn by his father back in March 1985, when Harry was just six months old. The Duke of Sussex was also at an airport when he wore the hat, having landed at Aberdeen airport with his mum, Princess Diana.

Unlike Archie, Harry’s 80s outfit was colour co-ordinated, as he wore an entirely cream look.

However, both baby Harry and baby Archie were cradled by their beaming mothers, making for sweet comparisons between the pair.

Fans were quick to notice the tribute, and rushed to Twitter to comment.

One wrote: “The only difference…Archie 4 months while the Duke was 6 months old. I think Archie is very much like his father.”

Another said: “Aww what a resemblance! Archie looks like dad”.

The family have a busy schedule ahead for the tour, although it has not been confirmed when Archie will apear and when he will stay in the hotel.

Meghan and Harry will spend the first couple of days together in South Africa before Prince Harry flies solo to Botswana, Angola and Malawi.

According to royal correspondent Katie Nicholl, the Sussexes landed in South Africa at around 8am (BST) this morning.

They are expected to attend their first royal engagement at around 1.30pm local time (12.30pm BST) this afternoon.

Their first official visit will be to a workshop which teaches children about their rights and provides self-defence classes.

The Duke and Duchess will then tour the District Six Museum, a memorial to the 60,000 residents forced from their homes in the area during apartheid in the 1970s.

Meghan and Harry will hear about the work being done to reunite families separated by the regime. They will then join a community cooking activity with former District Six residents.

All eyes will be on the Duchess of Sussex and what she is wearing – however, the Duchess of Sussex has made a number of basic fashion errors on royal tours in the past. These include one embarrassing moment when the mum-of-one left a tag still on her dress.

Of course, it’s pretty normal for the average person to have creases in their clothes, but royal women are under extreme scrutiny. How do the likes of Kate Middleton steer clear of creases? The answer is a stylist.

Fashion PR expert Dominique St. Johns told Express.co.uk: “It is said that Meghan does not have a stylist, which could be seen as an advantage as she handpicks her clothes herself.

“This has led to incidents in the past such as leaving the label on a dress or turning up to an event with a blouse slightly creased. This doesn’t reflect anything about their attitudes to royal duties, but that they are human and that mistakes can happen.”
