Donna Air wears flame-patterned skirt as she joins toyboy James Middleton at Serpentine Summer Party

As a red carpet regular, Donna Air usually goes for a more classic approach when it comes to her style.
However, with dozens of big names clamoring for the spotlight at the Serpentine Summer Party on Wednesday night, the Geordie beauty had to push the sartorial boundaries a little more than usual.
Arriving on the arm of her boyfriend James Middleton, the model, 33, wore an unusual ensemble of a turquoise blouse and maxi skirt with a flame pattern on the hemline.
