Your clothing will be as described in Rev 7 8-14. (Look it up!)

White Robes - Doh! I've given the game away - signify royalty, and they also signify holiness - not just the absence of sinfulness but positive righteousness.

We have none of that of our own, so we have to get it from Jesus, hence the paradox in v 14, where red stuff washes dirty robes white.

Adam might not have worn clothes, but he was not in a state of Righteousness in the sense I have just used. He was in a state of the absence of sin, with the constant possibility (which came true) that he would fall.

If only he had taken of the Tree of Life - which signifies Jesus - instead of the other tree, then he would have taken Jesus's Righteousness upon him, and, I think, been arrayed in his white robes of royalty and holiness.

By the way - girls. - No! Your bums won't look big in these robes!
