There are many surviving pieces of clothing from hundreds of years ago, for example, there was a news story about a 500 year old incan girl that was preserved http://www.dailymail.co.uk/sciencetech/article-2179217/Inca-ice-maiden-frozen-human-sacrifice-infection-lungs.html
There are also a dress found that was 5000 years old that belonged to a mummy http://news.nationalgeographic.com/2016/02/160218-oldest-dress-egypt-tarkhan-archaeology/
Suppose that thousands of years from now , assuming humans all died , aliens found earth and investigated to find a bunch of fully clothed skeletons. The cloths on the skeletons, unlike the above examples besides being a little dusty, are in such good condition that they could be washed and worn again as if they had just come from the store
Is clothing that is able to withstand time like in the scenario above possible and if so what would make it possible for clothing to survive for hundreds of years and be able to be worn just like new?
