Princess Mary and her kids wear national costume for royal tour

Princess Mary is known for her keen eye for fashion, never putting a foot wrong in the style stakes.

But now, she has stepped out in a rather unusual outfit while visiting the Faroe Islands.

It's the first time Crown Princess Mary and husband Crown Prince Frederik have taken their four children to this part of the Danish realm.

The couple visited the region in 2005, accompanied by Denmark's Queen Margrethe and her husband, Prince Henrik.

This time, Mary and Frederik have decided to bring along Prince Christian, 12, Princess Isabella, 11, and twins Prince Vincent and Princess Josephine, seven.

The family travelled to the Faroes, in the North Atlantic sea, on board the Danish Royal Yacht, Dannebrog, which has been in operation since 1932.

Mary and her family arrived at the quay of Tórshavn, with hundreds of locals turning out to greet the royals.

In respect to their hosts, the Danish royals dressed in national costume – much to the amusement of Isabella and Josephine who were seen pulling funny faces upon their arrival.

The clothing features intricate weaving and embroidering, all made by hand from materials sourced from the islands. They all include a silver chain, buttons and a buckle.

The women's outfit includes an ankle-length skirt, topped with a shawl and pinafore and a cape to protect against the weather.

While the men's outfit features a woollen cap along with woollen knee-length pants, long knitted socks and a braided ribbon, to match the waistcoat.

The four-day visit will see the Danish royals experience the distinctive nature and culture of the 18 islands that make up the Faroes.

Their schedule is jam-packed, with day one including a visit to a school followed by an inspection of a new residence hall in the city centre.
