It's admirable that they show such dedication towards their community, but I can't tell anything about these people based on their clothing other than that they're amish.
interesting. i live among them, and so i can tell quite a lot. these are old order amish above, possibly swartzentrubers. they'll be full or part-time farmers, with occasional employment in day labor or other occupations. i knwo what color their houses are, what sorts of wiindows they use, the style and color of their window curtains, how they cook, heat, what they eat, what they believe about raising children, marriage, machinery, telephones, plumbing, and how they travel from place to place.
the ones below are beachy amish, with less strict beliefs about community and how it works, and they'll both farm and work in town at permanent jobs. they will use motors for farm traction, but no personal automobiles.
these are progressive mennonites, with even more liberal anabaptist beliefs, and might own woodworking or metal working businesses, for example. they'll own motorized transportation. they'll have telephones and electricity:
plain quaker:
it depends on what you know about them as to what the clothing tells you. i can do this not because the clothing indicates anything personal, but because the clothing is specifically associated with lifestyle choices. in terms of personality, the clothing is uniform, which is done on purpose because uniformity is a community choice.
the quaker is a computer programmer.
