Katie Green (born 28 August 1987) is an English model from Chichester, West Sussex. She was first given an opportunity to model when a Surrey photographer arranged a test-shoot for her at Image Park Studio in West Sussex. Green was originally signed to represent Wonderbra in July 2008, but her agency required her to lose weight, and she refused, ending her contract. Green is unusual among models because of her weight for someone her size and her refusal to lose weight to conform to the norms agencies expect of models. She initiated a campaign against size zero models with Liberal Democrat MP Lembit Öpik. Green continues to model and has appeared in numerous publications and campaigns.
