Last night we went to the NYC premiere of About Face: Supermodels Then and Now, which you can catch on July 30 at 9pm on HBO. Besides everything we learned from the models on the red carpet before the premiere, the documentary itself was really eye-opening. The models were frank and forthcoming about their experiences in the industry and we were absolutely riveted.

Since you won’t be able to see it for a few weeks, we thought we’d give you a couple peeks into the film. They’re not really spoilers, though. There were so many amazing quotables from the documentary that there’s no way we could possibly ruin it for you. So from racism and sexual harrassment to being told you have awful eyebrows, click through to discover 10 things we learned about the modeling industry and the personalities that shaped it (plus some awesome vintage magazine covers).
