Two great body image documentaries
It's more of a personal journey story, and talks about body positivity and some inspiring people who are working on it all over the world. I loved it and it really helped me think about my own situation. It's on Netflix.
Straight/Curve: http://www.straightcurvefilm.com/This focuses more on the fashion industry and its incredibly narrow vision of beauty. I loved this one too. I watched this on Epix.com. They're currently offering a free 30 day trial ( had to google it for a link), and I joined so I could watch the doc.
