Per the costume designer’s words, from a visual standpoint, Emma Stone’s Cruella isn’t necessarily similar to the 1961 version or Glenn Close’s character. The reason for this is the movie is a prequel, and she didn’t want to repeat herself with a Cruella de Vil who had not yet become the version we see in the previous movies. That said, Jenny Beaven did use Glenn Close’s character as a reference to imagine how she might have started before becoming her.
