I’ve been reading along for a while now and I don’t understand why you have questions.
While I don’t think I have read an answer for this question particularly yet, it has an easy answer.
Mt. 6
And
why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin: And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these. Wherefore, if God so clothe the grass of the field, which to day is, and to morrow is cast into the oven,
shall he not much more clothe you, O ye of little faith? Therefore take no thought, saying, What shall we eat? or, What shall we drink? or,
Wherewithal shall we be clothed? (For after all these things do the Gentiles seek

for your heavenly Father knoweth that ye have need of all these things. But seek ye first the kingdom of God, and his righteousness; and
all these things shall be added unto you.
He already said that he doesn’t talk to people about their clothes.
Modesty and dirt are not the same things. I have been to church with lots of people who wear the same thing every week and probably don’t change their clothes to sleep. Nobody kicks them out for dirty clothes. Dirt isn’t immodest. There were some people who were very inappropriate and immodest at church and were told not to come back because they were intentionally undressing for people. This used to be called indecency and in some places is an offense subject to arrest.
Others whose clothes did not have sufficient material to be called modest were offered clothes to cover themselves and be modest. If they chose not to respect the request of the church, they were requested to not come back until they were dressed modestly.
No, anyone given clothes was not forced to give the clothes back. They were gifted. If you really need clothes that badly, the church was happy to help.
Romans 14:5
One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.
Romans 14:14
I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
There is a principle in these verses that applies. If someone feels that they should dress a certain way for church and that to not do that is wrong, for them to not do it would be to sin against their own conscience, to willingly do wrong.
There is a moral teaching that is subject to standards but is an undeniable fact that God has given us clothes and that we need to be covered.
A little extravagant but it would work for church. I don’t like choir robes.
What about the rest of the week? Is it okay to cover what God gave you on Sunday and show it the rest of the week?
There is an acceptable amount of visible skin. To go beyond what is modest and wear what is suggestive and revealing is not modest and is not acceptable Christian behavior.
But if choir robes are the solution, don’t have a double standard for modesty, wear them all week.
