Nudity perspective from our first parents
But this knowledge was hidden from Adam and eve. In Gen. 2:23, Adam said this is now bone of my bone & FLESH OF MY FLESH. This acknowledgement Adam made shows that he was aware of his body but unaware of its appearance. He did not know if he was right or wrong to appear naked, the implications of exposing his nakedness and the feeling of shame that comes with it—
Genesis 2:25 KJV
"And they were both naked, the man and his wife, and were not ashamed."
Genesis 3:2-5 KJV
"And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:  But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.  And the serpent said unto the woman, Ye shall not surely die:  For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, b knowing good and evil."
Eve desiring to know more ate of the forbidden fruit with Adam. From the moment they ate the fruit, the first judgement of good and evil they experienced was their nakedness. Let us not forget that they were the only ones in the garden but when they discovered through the knowledge they received that they were naked; they suddenly realized they shouldn't expose themselves hence they found fig leaves and made aprons—Gen. 3:7. When God called on Adam, he responded (still on his apron) that as he heard God's voice, he hid because he was "naked" from the same God who created him. Gen. 3:9-11—confirming the knowledge they got from eating the fruit of good & evil.
In their heart, they thought that since they were naked, no one should see their features because they were sensitive and appealing to the eyes. They were conscious of each part of their body and thus covered them.
This is the TRUTH according to genesis 3:21 in which God himself clothed them from themselves and himself. Being naked created a sense which proceeds from the judgement made through the fruit of good and evil. These thoughts which are disturbing, came forth from self-inspection and realization that they were naked and hence should be clothed.
Nakedness was truly a symbol of lack of knowledge but then again when we get to heaven and when we dwell with God for eternity, we wouldn't again be naked. But look at what God says in the book of Revelation regarding clothing:
“After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;” – Revelation 7:9(KJV)
In the eternal state, we will be clothed in white, not naked. We will once again be completely innocent from sin, yet we will not be naked.
Being half or fully naked and displaying your body without shame was once an innocent thing done without shame or fear but the knowledge of the fruit has brought seeds into every human’s heart coated with self-awareness. Most people like the feeling of showing some skin or all the skin, wearing " fashionable" clothes as we call it. This reveals the skin from the neck to the waist, some of these clothes exposes the breast while some reveal the male manhood (largely shown) etc. These things are beautiful with the right tailor, they will blow your mind or provoke you.
But let’s think about it, we have lost the right to innocence from the garden. You can't wear what you like and allow another human being lust to sin because it’s what you desire while some will say it makes them look appealing, the common words used "sexy”. But carelessly at every corner, Christians dress so provokingly, forgetting it’s a sin to behold the nakedness of another. They do it with so much joy. Even when you correct this impression wickedly, they say someone has a psychological or spiritual problem for being carried away by nudity when scriptures have addressed nudity as a shameful act.
In our world today, humans purposefully seduce each other with their sexual appearances. They go half or fully naked exposing the body without thinking about the effect it has on the minds of others. These days we promote these things, provoking God day by day. This attitude is transmitted from generation to generation. The act of appearing naked or half-naked can bear iniquity in the heart.
Exodus 20:26 KJV
Neither shalt thou go up by steps unto mine altar, that thy nakedness be not discovered thereon.
Exodus 28:42 KJV
And thou shalt make them linen breeches to cover their nakedness; from the loins even unto the thighs they shall reach:
Yes, God was talking about the priest but let’s analyze the dress, these men were wearing lengthy garment but because they go up to the altar. God instructed them to make breeches. We are clothed to cover our shameful parts. Through our first parents, humans have analyzed that it is wrong for man to be exposed.
Don’t be deceived by people who make statements like "Christianity is from the heart for that purpose you can appear any way you choose to", hence they go almost naked. Check to make sure every outfit you wear is DECENT. Reprove it if it is revealing any sensitive part of your body that shouldn’t be seen at all.
We do not dress for ourself satisfactory pleasures alone but we do so to also please God and not for the pleasure of man and its daily trend to expose the human body and to please its sight. This will only lead to sin
