Beadnet dress from Egypt’s 4th Dynasty, during the reign of Pharaoh Khufu 2551–2528 BCE. It is the oldest surviving example of a dress in this style. And yes, it would have put the wearer’s body on display in a way that is barely acceptable at a burlesque by today’s standards.
The dress has been reassembled from approximately seven thousand beads (no record mentioned how long the reassembling took) found in an undisturbed burial of a female contemporary of Pharaoh Khufu. Although their string had disintegrated, a few beads still lay in their original pattern on and around the mummy, allowing modern archaeologists to accurately reconstruct what it had once looked like. The color of the beads has faded as well. But when it was first made, the beadnet was blue and blue green, to imitate the precious stones lapis lazuli and turquoise.
