The question needs to be more exact to be answered properly. Do you mean worn at all times? Or just during church ceremonies or on specific days deemed holy by the church? Define require. Was your intent to ask which Christian religions ASK that their believers wear certain types of clothing? Or do you mean require as in, a Christian religion who deems it sinful or against church doctrines to not wear the item/items of clothing? Perhaps it's just me, but the question seems a bit vague. Many Christian religions require certain clothing to be worn during ceremonies by specific people involved in said ceremony. For example, a Catholic alter boy wears robes while serving as alter boy. He is not clergy per se, but he is still required to wear the robe at times when it's appropriate. I believe the Mormons wear what are called garments which is a type of underclothing. However, I know many Mormons who refuse to wear them and find them unbearably uncomfortable. There is an AB section on this located here: http://www.answerbag.com/c_view.php/1449 I personally, know nothing about garments other than friends who have mentioned them in passing. If you wish to rephrase the question, I might be better able to answer it for you. Wish I had a better answer for you at present.

Anabaptist denominations Amish, "Black Bumper" Mennonite and Old Brethern all require a very consevative dress, with a head covering. The Amish are probably the best known, due to their relative isolation; yet images of them in various movies. They are required to wear the following: All: no modern fixings (no zippers, velcroe, buttons or pockets) Natural, homespun clothe. Doesn't have to be made by the wearer, but not made in a factory. The cloth is died by hand, thus there are limited colors. However, many people think the Amish only wear dark colors. When I went to college in the Hershey, PA area, I saw some women who wore dresses of a beautiful blue color. Additional strictures for Women: head coverings, uncut hair up in a bun, single color dresses with skirts down to the mid calf and longer. Additional strictures for Men: beards after marriage, dark suits, suspenders, straw or black hats. For more information on the Amish see http://www.religioustolerance.org/amish.htm http://www.800padutch.com/amish.shtml Mennonites have varying denominations, which range in their requirements. The more liberal Conservative Mennonite Church discourages immodest dress, meaning no mini skirts and such. The Old Order Mennonites were nicknamed "Black Bumper" in the Hershey, PA area because they would actually paint any chrome on the car black. Women and girls are to wear dresses below the knees and modest (I did see girls in short sleeves, but certainly nothing revealing, I don't know the specific requirements), in addition they are required to wear tie shoes and not to maintain a long hairstyle (no bangs, etc.) Two of my fellow students were girls from Old School Mennonite families. They, like the Amish, have a period of time that they can expand and experiement before they must decide to commit to the community or not. In fact the Old Order Mennonite and the Old Order Amish actually share their roots. The Brethren are much the same as the Mennonites as far as having several denominations that vary in strictness. I occasionally attended a liberal United Brethren in Christ church while in college. Some of the older women wore head coverings to church, but it was not required and considered a "older generation" practice. On the other hand, in my current state of VA, there are Old Order Brethren communities that wear clothing that remind me of the Old Order Mennonite communities in PA.

Not sure if they're a religious group in the US (where most of the ppl here seem to be) but in New Zealand there are quite a few Brethran, a type of Christianity. The women cover their heads with a scarf or headband and cover at least to their knees, the men also covered to the knees. They have quite a few strict rules - no TV, no computers, arranged marriages, etc.

My grandparents were old-fashioned Mennonite and the other set were old-fashioned Brethren. My grandfathers wore dark suits without ties, like Nehru jackets, in solid colors of black, dark blue, or grey. They wore long-sleeved white cotton shirts or long-sleeved flannel work shirts. No short sleeves were worn by the men, even in 3-digit temperatures. The ladies wore home-made dresses that covered from their necks to below the knees. Sleeves were worn at least to just below the elbows and captured there or at the wrists with fasteners. More of the farming community's dresses displayed a delicate looking, tiny flowered print. There were no fancy adornments. Some dresses had modesty drapings that fell from the necks to the waists. They looked like long bibs overtop the dresses and were worn either loose or sewn to the waists. This style dress provided a modesty coverup when a new mother needed to nurse her baby. The white, net caps worn over the never shorn hair worn in a bun were sometimes covered over by another opaque cap, which was black. Straight pins or bobby pins were used to keep all caps in place. One reason for dressing differently than other people is to show they do not walk the same walk as the world does, but seek to serve others as Jesus did. Several of my aunts chose nursing as careers. One is in her seventies and still a nurse. One was on the Board of the Gideon Bible Society. See, modest dress does not mean an ignorant person. Also, my parents changed to modern dress and Mother cut her hair. The world sees the dress difference in the Plain People and decides this is a requirement. But this is not a requirement for salvation, and none would say it is. It is just an adjustment of how to dress in order to uplift the community and show immediately that there is a distinctive adherence to following Jesus Christ as Savior. Learning how to live to honor God, learning about the reasons why the world lives and believes as it does, while adhering to faith in Christ, and showing forgiveness and love to all people, and telling them the Good News, is a lifelong duty and pleasure.

The answer is - Those religions, denominations, or cults that fear losing their hierarchal grip upon their subjects. The more strict the religeous taboos, the more afraid the powers-that-be are of losing their tenuous grip on their followers. Like any tradition, there was a time where these made sense. Don't eat pork (because under temperature cooking ensured the eater painfully suffered from trichinosis). Don't wear pants because men will have a more difficult time having their way with you sexually, because long skirts can be lifted and used as a blanketing device to ensure "co-operation". Today, things are different. What you say and what I hear are two different things. Don't wear clothing or don't act in any way that we think is unacceptable to us (the powers-that-be) because then you will have to think about what to wear, about what to do, and perhaps you will then think about your role (or lack thereof) in society, and reject the control we place upon your freedom. Some women I know wear short skirts and accept Jesus as their Saviour. Some women wear pants, or long or short skirts and don't think twice about God damning them for their dress. I believe God knows what's in their hearts, and doesn't give a hoot about their clothing, anymore than he cares about what kind of car you drive, or whether you're black or white, etc. (unless you use these things to control or bully others, or harm them).

I wear 'holy' underwear...

I think Mennonites are required to wear certain types :)

I think Pentecostals are very strict about women wearing skirts and dresses and not cutting their hair. I'm Fundamental Baptist and at my church we are taught that men and women should dress different from each other, including the hair. The Bible's very clear that men should have short hair. However, we don't have a rule that says you have to dress a certain way to attend our church. We allow anyone to attend. We're all sinners The more sinful we are the more we need preaching. Imagine a hospital that does not allow sick people to go in there. The whole purpose of the hospital is to make sick people well. When some Pharisees asked why Jesus ate with publicans and sinners, Jesus said,".....I am not come to call the righteous, but sinners to repentance."

I can't answer for other sects, but the Church of Jesus Christ of Latter-day Saints does require certain clothes under certain circumstances. Our sect has a lay clergy, so I've included dress standards for our priesthood holders as well as the general membership. There are standards for the various ordinances. In general, members dress in "Sunday best". For men, this normally includes a tie and white shirt. Converts must wear all white when being baptized. The baptist is also robed all in white. In our temple ordinances, patrons are dressed in white. Some ordinances require additional ceremonial clothing. After a Latter-day Saint has received a certain temple ordinance, they are instructed to wear a temple garment under their street clothes. This garment is sometimes ridiculed by outsiders as "magic underwear".

Let me educate you here with sound doctrine. These so-called religious experts in this subject do not know what they're saying. Read (Galatians 3:23-25). The passage mentions that after the faith/Jesus was revealed, we are no longer under a "schoolmaster." Only the cultish religions require certain dress codes to control their flocks. This is called being under the Mosaic law, which involved: men having certain dress codes, women are prohibited from wearing pants, and should wear long skirts instead, man cannot have long hair, women cannot have short hair, etc. In the New Testament, it is about freedom of expression to the point of dressing modestly to avoid sexual observation, and not freedom of expression to abuse of it. Let's use some spiritual knowledge: if women dress modestly in church, men will not lust. Check out this YouTube video to see what goes on in many churches. You will be shocked to see that the Bible means nothing to sideshow circus freaks who claim to be Christians: https://www.youtube.com/watch?v=mGfTbm76X2s

Hmm! Ever heard of Sunday suit?
