British tabloids dubbed her the “Discount Duchess” for repeating dresses from her own wardrobe last week, wearing a blue jacquard coat to a church service in honor of Prince Philip’s 90th birthday, which she originally wore to a friend’s wedding in 2009. Later that day, she also wore a black and white Zara dress from 2007 to a friend’s wedding, earning her a thrifty nickname.

However, the Duchess, “put her foot down when it came to interior design,” reportedly having over $1200 worth of candles and room sprays delivered to Kensington Palace to get rid of the palace’s “fuddy-duddy smell.” She is also rumored to be redecorating her quarters in an effort to modernize the 17th century palace. Sources claim that her interior design aesthetic mirrors her modern, sleek fashion sense.

Unlike Duchess Catherine, who refused an interview with British Vogue before her big day, Princess-to-be Charlene Wittstock, 33, posed for Vogue and sat for an exclusive interview only two weeks before her own royal wedding. She will marry Prince Albert of Monaco on July 2, 2011.

Vogue reported that Wittstock is friends with notable designers such as Karl Lagerfeld of Chanel, who helped her develop her fashion tastes while living in Monaco. She has already announced that Giorgio Armani is designing her wedding gown, and hopes “to make Monaco one of the fashion capitals of the world,” said Wittstock. “It would be wonderful to team up with some of my international fashion friends, like Stella McCartney and Ralph Lauren, and get the place buzzing with energy again.” She intends to inaugurate a Monaco Fashion Week.

Prince Albert and Wittstock attended the royal nuptials of the Duke and Duchess of Cambridge on April 29th. However, it appears the British royal couple will forgo the wedding of Prince Albert and Wittstock, as the wedding conflicts with their first official tour.
