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 was a shop assistant in West Sussex earning minimum wage in summer 2008 and considering applying to join the police force when she saw a magazine advertisement for a model to represent Wonderbra.

A week later, The Daily Express newspaper ran a picture of her on page three, asking readers to contact them if they knew who she was as she had been selected as the new face of Wonderbra.

[1] Green was signed by the Unleashed PR agency and became the new face of Ultimo's D-G range, alongside fellow model Melinda Messenger and the Spice Girl Mel B.

They began a petition drive with the goal to end size zero and underweight models on the catwalk or working in the fashion industry.

[5] On 26 September 2009, Ultimo stopped representing Green when she broke the company's "no nudity" clause in her contract by being photographed topless at various beaches.

On 29 September, Green came third in a national poll conducted by The Daily Star to find the perfect celebrity body, beating Cheryl Cole, Mel B and Victoria Beckham.

[1] Green launched "National Measure Your Bust Week" at Debenhams on Oxford Street in London during Spring 2009 with the Ultimo creator Michelle Mone.
