Princesses Maria Chiara and Maria Carolina of Bourbon two Sicilies have been photographed looking glamorous while shopping in Saint Tropez.
The Italian heiress sisters were born to Prince Carlo, Duke of Castro – who claims the now-defunct throne of the former House of Bourbon-Two Sicilies – and Princess Camilla, Duchess of Castro.
Their appearance comes amid rumors that younger sister Chiara, 18, is in a relationship with Prince Christian, heir to the throne of Denmark.
There was speculation after 17-year-old Christian was photographed on a day out with friends at the Monaco Grand Prix in May, standing close together with Rome-born Chiara in a group photo taken at the event.
His parents, Crown Princess Mary, 54, and Crown Prince Frederik, 55, are family friends with the parents of Carolina, 19, and Chiara.

The sisters seemed to enjoy their stroll through the city, which is known as a glamorous destination
The Italian sisters have already spent some time this summer in St Tropez (where Chiara was photographed eating ice cream with Christian), and they seem keen to make the most of summer in the glitzy French Riviera town.
Stepping outside today, the siblings looked typically dressy, in casual but carefully curated outfits.
Older sister Carolina opted for a sporty combo outfit, matching a cropped pink t-shirt with matching leggings.
She completed the ensemble with a pair of nude wedge sandals with a straw heel and a matching miniature straw bag.
Her long blonde locks were pulled into a high ponytail and held in place with a hair elastic decorated with fabric flowers, and she looked fresh.
Meanwhile, Chiara wore a mini dress with a halter-neck style top and a waist cinched with a matching fabric belt.
The short dress is made of a white cotton fabric with a multicolored floral print.
Like her sister, she also wore a pair of wedges, which both looked dressy and seemed more practical for navigating the cobbled streets than heels.
It is rumored that Prince Christian of Denmark, the son of Crown Prince Frederik, is in a relationship with Chiara

Her long blonde bob was neatly styled to fall right past her jaw, and she completed the look with a bright yellow bag slung casually over one shoulder.
The House of Bourbon-Two Sicilies is a cadet branch of the Spanish royal family descended from the Capetian dynasty that ruled southern Italy and Sicily in the 18th and 19th centuries.
Although the family has no official duties, they devote their time to charitable work and promoting the interests of southern Italy.
And the two sisters are also actively involved in charity work, collaborating with Europe’s most elite socialites, who speak fluent English, French and Italian.
