Yes, thanks for that. Acceptance is one issue that I think is at the heart of it- the idea that acceptance by God and acceptance by one's peers (eg. external pressures) are at the heart of the matter is something I am going to have to explore.
You might find it more of a "pressure" thing in certain countries, specifically certain *parts* of countries.
I know in PA Dutch country, if you're not Amish or Mennonite, there's not much pressure as to what you wear for church. But, in the Amish/Mennonite world, you wear and live how they say in the ordnung and no differently. Same in other areas heavily Older order Anabaptist.
In the Bible Belt, it depends strongly on your denomination. You know the AOG/COG people from the get-go, by how they dress. You may or may not be able to identify the various baptist groups by their dress, but in general, the older women usually wear Ladies' suits or dresses, and they aren't cut below a certain amount or above a certain amount. There's usually a great deal of pressure on the younger women to conform to a similar style of dress. Also, depending on the type of baptist, only skirts/dresses are acceptable, and sometimes culottes are acceptable if they're knee or longer length. Other times, there isn't that much control over what is acceptable wear when you are at home on your own.
I don't know many in either group that cover, but
some AOG/COG feel very, very strongly about the length of women's hair and not cutting it or shaving other hair.
It's a sin you just don't ever want to do.
I think it was the 7th day Baptists that cover. I haven't met very many, but those I had contact with - the women cover, similar to Mennonites.
Some within other denominations cover, but maybe not to the extent you find at modestworld.com or tzinius.com - just a kerchief or hat or such carefully placed. Sometimes it is very strongly discouraged by the other women, and sometimes the pastor or deacon/elder board. It just depends on the congregation and it's politics, as well as the level of control they have over the members. They'd not dare discourage a woman with cancer from covering her head though.
