Pip Edwards and Nadia Bartel cut stylish figures as they lead star arrivals for Witchery’s annual White Shirt Campaign

Pip Edwards and Nadia Bartel rocked stylish ensembles as they attended Witchery’s 16th annual White Shirt Campaign at the Sydney Opera House on Tuesday.

The stars looked trendy in a white-collared OCRF shirt from the brand as part of the campaign – with Witchery donating 100 percent of gross proceeds to charity.

The fashion entrepreneur wore gold earrings and wore sunglasses, while her hair was styled straight with a center parting.

Meanwhile, Nadia, 38, teamed the same white button-up shirt, a long black skirt and a black handbag.
