You may have heard of the Korean mummies: this term refers to the extremely well-preserved bodies recovered from the royal tombs of the Joseon dynasty [1392-1910].

About 100 royal tombs have been excavated to date, and their well-preserved contents have given scholars insight into the culture of the 500-year old dynastic reign in Korea, including everything from the clothing people wore to their general health and diseases.
While I love the photo above too much to take it out, I have a sneaking suspicion that it is not necessarily typical Joseon clothing. I just found a photo on Flickr of a display in a Korean National museum which is probably closer to the reality.
