"gave him a vaguely Amish appearance"

The Amish are a Christian church related to the Mennonites. Formed in the late seventeenth century Switzerland by Jakob Ammann, the Swiss, German and Alsatian followers of Ammann's teachings emigrated to Pennsylvania in America in the eighteenth century.

The church is known for its adherence to strict rules regarding modest dress, simple rural lifestyles, and an avoidance of modern technology. This has made the Amish a constant source of fascination and antagonism in the outside world. Amish people can be  subject to abuse when interacting with wider American society, as their horse-drawn buggies and modest dress code make them stand out. Conversely, their lifestyle has also drawn interest from the outside world. The 1985 film Witness, starring Harrison Ford, was set within the Amish community.
