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 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 with Liberal Democrat MP Lembit Öpik. Green continues to model and has appeared in numerous publications and campaigns.
Katie Green is the youngest of four children. Her parents live in West Sussex, England. Green is 5 ft 10 in (1.78 m) tall and in May 2011 weighed 10 stone 5 pounds (66 kg; 145 lb). She was first given an opportunity to model when a Surrey, England photographer arranged a test-shoot for her at a photographic studio in West Sussex. She subsequently modelled for a group of photographers on a regular basis to gain experience. She was then introduced to a top London photographer for whom she began to regularly model. She applied for FHM's High Street Honeys competition in 2007, getting into the top 10 in 2008.
