I saw a mention of this movie online and went and found it this weekend - it follows a group of 1933 Vassar graduates as they move into their adult lives. Starring Candice Bergen, Joan Hackett, Jessica Walters, and Shirley Knight. Also a young Larry Hagman, Richard Mulligan, and Hal Holbrook.
It was good - really interesting perspective of marriage, relationships, careers during a time period when I think our perception is that women were without a lot of rights or ambitions.
I watched it on Tubi, but I think it's on other platforms too.
