To offer a little different perspective on this whole conversation...
When missionaries first went into some of the more 'primitive' areas of Africa, the villagers they encountered wore little or no clothing at all. This was the custom of that culture and no one thought anything about it being immodest. Well, one of the first things that the missionaries did was to insist that the women start wearing skirts and blouses so that they would be 'modest'. It didn't take very long at all before they realized that was a BAD idea. The sight of the women covered caused all kind of lust problems in the men of the village--since they were now using their imaginations to try to figure out what was under those skirts. The missionaries literally had to go take back the clothing from the women and tell them to go back to being nude, or wearing only a loincloth.
My point is that every culture has different views of what is/is not modest. Even within a particular culture those standards change with time. Not long ago, it was standard practice for men to wear wigs, makeup, and high-heels (ever look at any paintings from the 1700's?) Obviously that standard has changed significally. In Great Britain it is still considered normal for a man to wear a skirt (kilt) to formal events. In some cultures today, if a woman's hair is not completely covered so that none of it is seen at all then she is considered promiscuous and in some cultures the only thing allowed to be seen of a woman is her eyes--to show any more could get her stoned.
Well then, how in the world does one interpret scripture regarding these kinds of issues when there are so many cultures and they constantly change?
The first thing we do is find out what was written to a particular group of people in scripture. Then we look for the 'eternal principle'-- the real meaning of what was being said that applies to ALL people of ALL time and not just that particular group. Then we look to see how to apply that principle in our day and culture.
In scripture we see a culture where the only women who wore short hair (actually their heads were shaved many times) were temple prostitutes. Paul writes to that church and tell them for the women to not do something that would make them be confused for a prostitute. (He also ends the passage saying that it is not a 'law'). Well, the eternal principle from that should be obvious-- don't look like a prostitute (whatever that may mean in your particular culture).
There is a passage in the OT that says a woman shouldn't wear a man's clothing and vice versa. Well, in India women wear under their sari and men frequently wear a long wrap around their waist that look like a skirt. We've already mentioned that men used to be the ones who wore high heels, not women. How do we apply this eternal principle? It will apply differently in all the world. I would say that women should go to the women's department of the store and buy whatever they sell there and men should go to the men's department and buy whatever is there.
Finally --passages about being adorned with godliness rather than with gold and braided hair. The emphasis here is not to do things that make you 'stand out' and draw attention to yourself, as someone already has said. Unfortunately, many Christians today take pride that they do 'stand out' by the 'holiness' way the dress. By taking many of these issues to such an extreme, I would say that many of them have actually broken the intent of the passage.
Now I will be the first to agree that Christians are to be different from those that don't know Christ yet. But that difference is to be first and foremost an inner difference-- a difference of heart, a difference of spirit. We are to walk in love, in peace, in joy. Jesus railed against the religious leaders of his day that were 'white-washed sepulchres filled with dead men's bones'. They took great pride on how 'godly' they looked on the outside but had missed the point completely. Just so I'm not misunderstood, most of those I know in the 'holiness' camps really love the Lord and are trying to live for Him. But so many times, I feel they have gotten sidetracked with some of the minor issues and made them such a big deal that they are actually harming their witness-- not helping it.
