Oldest surviving piece of clothing resembles an ancient rag

Preserving a piece of fabric for over five thousand years results in a garment that looks exactly as terrible as you would expect.

While highly historically significant, the stained, tattered shirt definitely wouldn't survive a modern wash cycle.
