Olivia Wilde wasn't the only A-lister to do the casual chic thing in New York on Monday night. Cameron Diaz swapped party style for dressed down attire at the Greenhouse Project Benefit and proved that sometimes, simple is best.
Diaz paired her cropped trousers with ankle boots, a grey t-shirt and a navy blazer and although her hair and makeup was fuss free, the actress didn't forget about her nails. The colour-popping coral shade completed her relaxed look perfectly. Well played.
