Britain is weighed down by the biggest breasts in Europe. The average chest size of a British teenager has grown dramatically over the past 10 years and is now a whopping 36D. For some young women this is a cause for celebration, for others it can lead to a life of misery as they face bullying and physical pain. Thousands of teenagers - some as young as 13 - are now going under the knife in order to reduce their bust size and "fit" in. This documentary follows the lives of three women who feel defined by their naturally large bust size. One is terrified of having breast reduction surgery but with her breasts causing her chronic back pain she knows it may be her only option. Another hopes that alternative therapies and an exercise regime will downsize her chest; and the third, a fashion student, struggles to be taken seriously in a world where she feels only women with 'small boobs' can look attractive.
