The "dolls" in the title are not the three heroines trying to make it big and become famous. The dolls are the pills they take (uppers and downers) to survive in that dog-eat-dog world. I never saw the movie, but it looks deliciously camp (even more so than the book!). While the book was pretty silly, I will say it's scared me off of "dolls" for life. They're dangerous! (Sidenote: Um... that jumpsuit Sharon Tate is wearing is everything.)
Also dangerous? These hairdos! They're killing me! I love them so much. Super high and super straight with some serious flip action. Full of va-va-voom. If I was a less lazy person, I think I'd like to have hair like this. It is so fun and fabulous. Not fun and fabulous: the lives of these ladies! They may look glamorous, but, trust me, every one of them is a total mess!
