Amadeus: Mozart’s Sippers Didn’t Exist Yet
The movie gave us a glimpse into what Mozart’s life was like during the 18th century in Austria by allowing us to see it through his eyes. Regardless of how stunning the film was, it was not enough to make up for the fact that the intricate costumes should not have had any zippers that were visible.

It is more accurate to say that zippers should not exist at all because they wouldn’t be invented for another century or so at the earliest.
