A peplos (Greek: πέπλος) is a body-length Greek garment worn by women dating to before 500 BC.

The peplos is essentially a tubular cloth, folded inside-out from the top about halfway down, so that what was the top of the tube is now at the waist and the bottom of the tube is about ankle-length. It is then gathered about the waist, and the open top (at the fold) pinned over the shoulders. The top of the tube (now inside-out) drapes over the waist providing the appearance of two pieces of clothing.
