Even if you do not know what weightism is, you could observe this phenomenon in life, especially if you suffer from overweight.
Weightism is a form of discrimination experienced by people with excess weight.
Even plus size models have experienced weightism. This was told by a new documentary, A Perfect 14, where the main characters are three plus-size models (with the size 14, hence the title). However, the aim of the film shot by Canadian filmmakers is not to describe lives of plus-size models, but to show the difficulties faced by overweight people in life and plus-size models in particular.
Girls from the film insist that they have the right to be themselves, and they want to be heard. You can find the movie trailer below.
