Donna Air Is Pretty In Electric Blue Print For Charity Event At The Dorchester

Donna Air's fashion is really getting under our skin.

In a good way.

The 34-year-old is the perfect poster girl for ladylike fashion, on and off the red carpet. She never looks anything but immaculate whether she's strutting the streets of London town in a smart coat, enjoying date night with James Middleton in a cute mini dress or out with her gal pals in a variety of smart ensembles.

For her latest outing - co-hosting a party to raise money for UNICEF with at The Dorchester Hotel - Donna was her usual sleek self in a floor-length oriental dress, complete with jaunty blue florals and thigh split. It's eye-catching, yes, but also chic, simple and a spot-on choice for the occasion.

The do launched's charity auction of luxury amazingness (we're talking seriously beautiful dresses not to mention the actual t-shirt Harry Styles wore to Burberry's SS14 show) which starts on November 13th for five days. All proceeds will go to UNICEF.

Loved Donna's look as much as we did last night? See more delights from her wonderful wardrobe below...
