in my experience, most of the churches, ranging from old order amish or mennonites and at least on up to the "moderate conservatives" would not encourage/allow the women to wear fringes or dye their hair. i don't believe i ever read any rules about this-it was just a sort of unspoken thing. in the more "liberal" churches, i am not sure what is required of church members, though i would imagine it to be less strict. in the past few years the moderate conservative elements have adopted what is seen to be a "trendy" hairstyle amongst the younger girls and women, in which the hair is plastered against the head with a side part in the front and then brushed backwards in the back. this is very obviously an attempt to give the appearance of "side-bangs",which have enjoyed quite a few years of popularity in the general society. regarding dying the hair, i would not at all be surprised if some of the "moderate conservative" women might dye their hair (i knew a few who did), but it is not the general custom. sensible shoes and comfy clothing is indeed favoured by the plainer mennonites, but i do remember that even in some of the "plainer" churches, some of the women did wear pumps to church or for special occasions, such as weddings. also, many of the women favoured quite elegant, slightly more expensive and dressier fabrics for their sunday and special occasion dresses- with the look of silk or satin or other luxury fabrics.
