Here's why:
* General Shape: The sunglasses in the movie have the classic Wayfarer shape, characterized by their distinctive rounded rectangular frames.
* Popularity: Ray-Ban Wayfarers are iconic and were incredibly popular in the 1980s, the time period the film is set in.
It's important to note that the film's aesthetic was heavily influenced by the 80s style, and the Wayfarer sunglasses fit perfectly into that retro look.
However, without a specific close-up shot or official costume information, it's impossible to say for sure which exact model or variation of the Wayfarer was used.
