You can see in the photo above of Margot Robbie as Sharon Tate that they took care to retain the resemblance between the actresses.
I never would’ve imagined that as an early discussion topic, but Margot Robbie told Net-a-Porter it was one of the first things she asked Quentin Tarantino.
Robbie was trying to respect the real-life woman — and so was QT, who (wisely) decided that aspect of Tate’s physicality wasn’t exactly crucial to her story.
Then again, it’s no surprise that everyone involved would want to pay strict attention to the details.
