I'm not sure but I think you have put documentaries up for submission before so I wanted to suggest Unzipped. It follows designer Isaac Mizrahi through the creation of his 1994 fall collection. it's a really great look at fashion before it was all celebrity driven although a lot of celebrities do show up. It documents the peak of the supermodels. The filmmaker is Mizrahi's boyfriend at the time so some of it is incredibly personal. It's so 90s it's painful.
June is Pride Month so I thought it would be a great film to talk about.
