Dutch supermodel Doutzen Kroes conveys an insouciant sexuality in the March issue of Harper’s Bazaar. She’s a portrait in white casual elegance, showcasing spring collections.

Kroes gave birth to her first child, son Phyllon Joy Gorré with DJ husband Sunnery James in January last year, and was back in model form in less than two months.

She was most recently spotted in Miami on a Victoria’s Secret swimwear shoot with models Behati Prinsloo and Candice Swanepoel. She looked at the tip top of her game.

For her Harper’s, she posed for photographer Daniel Jackson with styling by Alastair McKimm. She wears Chloe, Lanvin, Stella McCartney, MaxMara, Givenchy, Calvin Klein and others in ivory and white. The 11-page spread is titled “The New Looks for Spring.”

The 27-year-old model, who is a leggy 5’10” tall, is repped DNA Model Management. like a number of other models, she’s working toward a film career.

She debuted last November in the Reinout Oerlemans film “Nova Zembla.” It’s the first Dutch 3D Movie ever made. The historical drama is about the last voyage of Dutch exploers Willem Barentsz and Jacob van Heemskerk.

They sailed north in 1596 searching for a North East passage to the Indies over the pole. They got stranded on the island of Nova Zembla off the Canadian coast for a year. Kroes has a small part as Catharina Plancius.

Kroes, who has also been the face of Gucci, Tommy Hilfiger and Versace , is one of the world’s highest paid supermodels, earning $6 million between mid-2009 and mid-2010, according to Forbes magazine.

In an interview last year, she said she isn’t getting as much catwalk work as she used to because she’s too curvy. “I have to work really hard. My body, I have a voluptuous body. I am not one of those skinny girls,” she said of her 34-24-24 figure.
