Men's and women's spiritual character is not defined by their physical appearance. Godliness is not a factor of how much clothing one wears.
However
outward clothing should reflect the inward state of a man and this is what it means by dressing modestly.
Ezekiel 7
They will put on sackcloth and be
clothed with terror. Their faces will be covered with shame and their heads will be shaved
In the bible the wearing of sackcloth was a sign of grief and mourning and clothes were used as an outward expression of the inward state. This was the same for priests who had certain dress that was worn to represent their inward devotion to god.
2 Corinthians 5
Our Heavenly Dwelling
1Now we know that if the earthly tent we live in is destroyed, we have a building from God, an eternal house in heaven, not built by human hands. 2Meanwhile we groan, longing to be clothed with our heavenly dwelling, 3
because when we are clothed, we will not be found naked. 4For while we are in this tent, we groan and are burdened, because we do not wish to be unclothed but to be clothed with our heavenly dwelling, so that what is mortal may be swallowed up by life. 5Now it is God who has made us for this very purpose and has given us the Spirit as a deposit, guaranteeing what is to come.
Not only is nakedness always associated with shame in the bible but clothing is associated with salvation and notice how being naked is again depicted as being undesirable as it says we do not wish to be unclothed ie the writer would not of his own free will walk about naked as naturists do as it is better to be clothed.
Galatians 3
Sons of God
26You are all sons of God through faith in Christ Jesus, 27for
all of you who were baptized into Christ have clothed yourselves with Christ. 28There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus.
Again clothes are associated with those who have been saved ie being clothed is like becoming a christian and this is more evidence that being clothed is desirable and biblical.
Isaiah 61
10 I delight greatly in the LORD ;
my soul rejoices in my God.
For he has clothed me with garments of salvation
and arrayed me in a robe of righteousness,
as a bridegroom adorns his head like a priest,
and as a bride adorns herself with her jewels.
Again being clothed is likened to being saved.
John 19
The soldiers twisted together a crown of thorns and put it on his head. They
clothed him in a purple robe
Again clothing is a symbol reflecting that jesus really was a king.
1 Corinthians 15
53For the perishable must clothe itself with the imperishable, and the mortal with immortality. 54When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: "Death has been swallowed up in victory."[
1]
55"Where, O death, is your victory?
Where, O death, is your sting?
Again clothing is symbolistic of what is happening.
1 Corinthians 11
3Now I want you to realize that the head of every man is Christ, and the head of the woman is man, and the head of Christ is God. 4Every man who prays or prophesies with his head covered dishonors his head. 5And every woman who prays or prophesies with her head uncovered dishonors her head--it is just as though her head were shaved.
Here the fact that the woman wears a covering symbolises the headship/authority of men over woman.
When Isaiah was commanded to preach naked his nakedness was a sign to show the people how they had rebelled against god.
The way christians dress outside should be a sign of their inward state and we also need to remember that being naked symbolises shame and rebellion against god as shown by isaiah and saul (remember saul had rebelled against god by trying to kill david and his nakedness symbolises this) and in other passages i listed in previous posts (see page 25 for verses) and so
for a christian to go around naked would symbolise that they had rebelled against god which is completely inappropriate and false. Our clothing should reflect the fact that we are christians and should be modest so as it does not cause others to lust and we should not judge others by what they wear (unless it is immodest or offensive) but by their deeds.
And, of course, it's a sin for a woman to even show her face in public - because women's faces can cause lust, too. Back to the idea of blaming the woman because someone else lusts. That's THEIR problem, not hers.
The bible clearly shows that there is nothing wrong with a woman showing her face in public but the bible also says that women should dress modestly as woman can easily dress in a more modest less provocative way that will not tempt men and the bible does not go to such an extreme as you are suggesting.
