It depends on the sect, but yeah for the most part it is. Once they cross that line it’s Mennonite. but there are some sects, like the Swartzentroubers, that are very old order and don’t even wear shoes. But for the most part they won’t. Even the dolls at Amish stores don’t have faces. And they may make exemptions for hijabs but there still has to be a photo and they just outright refuse for the most part, except for during rumspringe
