Actual plainness (solid colors, simple print, limited-palette wardrobes) is a hallmark of the plain-modern look. There are neither anachronisms nor symbolically and there are no traditionally important items.

I am not Amish or Mennonite, but some people who come to my website are interested in knowing more about these groups. I can recommend these books as authoritative and relatively inexpensive sources of further information.
