Nakedness in the Bible When Adam and Eve first eat the forbidden fruit, they put clothes on to hide their nakedness, indicating man was meant to be naked. However, angels show up in the Bible "dressed in white garments". 

Why would angels wear clothes when they are holy?
Both nakedness (and the awareness of that nakedness) and white garments are symbols (this does not mean we are not talking about real things, just that they are also symbolic).

White is a symbol of purity. For example, Revelations 3:5


  5 He that overcometh, the same shall be clothed in white raiment;
  and I will not blot out his name out of the book of life, but I will
  confess his name before my Father, and before his angels.


Here, the saints are given white garments to symbolize that their sins are taken away and that they are pure. Similarly, white garments symbolize purity and holiness when seen on the angels.

Next, the clothes of Adam and Eve. God created them naked, so there can't be anything wrong with that, really.

Genesis 2:25


  25 And they were both naked, the man and his wife, and were not
  ashamed.


Note the addition "they were not ashamed".

Next, when they eat the fruit:

Genesis 3:7


  7 And the eyes of them both were opened, and they knew that they
  were naked; and they sewed fig leaves together, and made themselves
  caprons.


And then they hide themselves. In that moment, they did something wrong and they are


aware of being in sin
aware that they are "naked" before the Lord, in other words, he knows what they did. They try to hide their sins from him. Nakedness could also be a symbol of the sinfulness itself (although that doesn't make sense since they were created naked), but important is that it is only a symbol of something happening in Adam and Eve. Before sinning, they are also naked, but not ashamed, because there is nothing to be ashamed of. After sinning, that nakedness is a problem for them.


Adam hides, is called out and has to take responsibility. And then, God does the following:


  21 Unto Adam also and to his wife did the Lord God make coats of
  skins, and clothed them.


In the end, God covers their nakedness. Much symbolism and promise in that action, if we take nakedness to symbolize sin. A foreshadow of Revelation 3:5, if you are with me. Either way, God makes clothes for them, so we shouldn't say that clothes themselves are something bad, unwanted, or sinful (or symbolizing sin).
