The Huns wore silk to protect themselves in battle. There were no bullets back then, just arrows and blades. While the arrows could still penetrate the flesh, they often did not cut through the silk which made it easier to remove the arrows and stem the bleeding. BTW, like tee-shirts, silk is imprintable -- "We're on the run, we're lotta fun, we are the Huns!"
Yes, that's actually true! They also wore silk scarves to prevent neck chops, because "there can be only Huns!"
