The Duchess of Cambridge is famed for her fashion sense
What will Kate Middleton wear in New Zealand and Australia is probably the biggest concern for media. reuters

Though still kept under wraps what Kate Middleton will wear on the upcoming tour of New Zealand and Australia, little detail of the Duchess of Cambridge's dress has been revealed.

According to UK's fashion magazine Grazia, Kate has picked at least one gown from the high-end brand Ralph & Russo that she will wear in Australia.

"Kate visited Ralph & Russo's boutique last month and said she was looking for inspiration for the tour," a source told the magazine.

"She liked that they had Australian connections and has apparently given them specific instructions for a gown."

Founded by Australian couple Tamara Ralph and Michael Russo, the couture label is a favourite of celebrities like Beyonce and Angelina Jolie.

Kate also is expected to wear bespoke designer outfits by her favourite designers, including Alexander McQueen and Alice Temperley.

However, the 32-year-old mum, who is known for sporting high street dresses as elegantly as a high-end gown, is most likely to be seen in store-bought outfits as well.

In total, the Duchess will reportedly have more than 30 dress changes during her three-week tour, which begins on Monday.

"A number of outfits she's wearing on the tour are off-the-rack pieces, however they're being tailored to her body shape," a source was quoted as saying by the US Weekly.

Besides, as reported earlier, Kate will wear low hemline dresses as suggested by the Queen so that Catherine doesn't have to face any embarrassing situation. Frilled and frock dresses is a strict no-no.

Prince William and Kate Middleton begin their tour of New Zealand and Australia on 7 April. Accompanied by Prince George and his new nanny, Their Royal Highnesses will conclude their tour on 25 April.

As much as the fashion statement of Kate, royal baby George is going to be the major media interest during the tour.
