Sue Lyon

Guess we all know which issue of Vanity Fair Gary Glitter owns. Madonna stole Sue Lyons ENTIRE Kubrick's Lolita look when at the age of 35, Madonna in all her sheer grotesqueness posed as an under age girl looking overtly sexual. Madonna's face was already lined, wrinkle and haggard far beyond her years so the pics were heavily softened and retouched. In the digital era madonna NEVER would have been able to get away the sexualization of children's imagery-that or she'd be competing with Katy Perry.

Maya Deren

Another 'reinvention' from the 'original queen of pop who pushed boundaries and inspired everyone'.
On the right Madonna in the music video for 'cherish' on the left side Maya Deren starring in the movie 'At Land' who copied the queen and backed in time to 1944 to make it look like Madge copied her.

Madonna deliberately copied her gamine look (hair, striped shirt, jeans, belt) in the Papa Don't Preach video. Why was Madonna pretending to be a pregnant teen with her teddy bear when she was 28 years old?
