Why Adam and Eve were created naked?

What are the the common explanations in the Oriental Orthodoxy, the Roman Catholic Church, the Eastern Orthodox Church and in the main-stream Protestantism (I mean those protestant believers who besides praying to the Father also pray directly to Jesus) on the reason why Adam and Eve were created naked by God? On one hand, we see throughout the whole Bible that angels are never naked. They are always dressed in bright and white robes. In the book of Revelation we see that in the eternal future all the saints will be wearing white robes. On the other hand, God said, after creating humans, that all the things that He had just created were "very good". So what is really "very good"? Is it to be naked or to be clothed in white robes? If robes, then why Adam and Eve were not originally created that way, that is, with white robes on?
