Green was originally signed to represent Wonderbra in July 2008, but the Premier Model Management agency immediately pressured her lose 2 stone (28 lb; 13 kg) and two dress sizes. She ended her contract in October 28 when she refused to lose weight. She shortly afterward signed a contract to represent Ultimo which continued until October 2009 when Ultimo released her when she was photographed either nude or topless in violation of her contract. Green is unusual among models because of her height and weight and her refusal to lose weight to conform to the norms agencies expect of models. She initiated a campaign against size zero models. Green continues to model and has appeared in numerous publications.
