Katie Nicholl, author of Harry and Meghan, said the Duchess of Sussex, 37, will take a “mindful” wardrobe with her for the visit.
The stylish royal’s wardrobe during her tour to Australia, New Zealand, Fiji and Tonga last October was estimated to have cost over £118,000 ($A212,000).
But Katie said Meghan will think carefully before donning eye-watering price tags on her trip later this year, The Sunreports.
“I think Meghan will probably be very mindful of where she is visiting.
“I think it is safe to say it’s going to be a working wardrobe with some designer elements, instead of a designer wardrobe that does all the talking.

“I’d also add she does on duty workwear really well. Meghan to me is the absolute master or connoisseur of the capsule wardrobe.
“I remember watching her on tour in Ireland and that basic wardrobe of cropped pants, basic shirts, blazer and then a smart fitted dress for the evening, seems to see her through her working days.
“She will want to reflect the culture and the traditions and the heritage in some of her wardrobe.”
Katie pointed out that when Meghan visited Africa for charity work when she was starring in the hit legal drama TV series Suits, she was “casually attired”.
She added: “I think common sense will probably prevail when it comes to her wardrobe.
“I think all the emphasis will be on the work they are doing, rather than what she is wearing, or at least that will be the intention and her hope I would have thought.”
“When we’ve seen her travel to Africa previously, which she did when she wasn’t the Duchess of Sussex, she dressed appropriately for where she was with the climate.
“I think until we see that itinerary and know whether there will be State dinners or black tie receptions, it’s very difficult to know what exactly she will be wearing.”
The trip to South Africa and Botswana was confirmed in June, with the royal Instagram account excitedly adding: “This will be their first official tour as a family!”
Considering Archie will be less than six months old at the time of the visit, it wasn’t known if the royal couple would bring their son along.
But the royalsussex social media account suggested he would be joining them, saying: “This will be their first official tour as a family!”
If Archie is brought on the trip, Katie said we shouldn’t expect to see a whole lot of the youngster.
She said that the young royal won’t be “paraded” on the tour as Prince Harry “doesn’t want him to grow up with the burden he did”.
