The kolpos (Greek κόλπος, breast) is the blousing[1] of a peplos, chiton, or tunic in Ancient Greek clothing, whereby excess length of the material hangs folded over a zone (a narrow girdle).
The fabric of the garment was typically cut longer than the shoulder-to-floor measurement of the women or men wearing it.
To create the kolpos, a zone was tied around the body below the breast (high-girdled) or at the waist (low-girdled) and excess fabric was pulled up over it.
The fabric fell over the girdle so as to hide it, and was often pulled longer in back than in front.
A second (visible) zone could be tied over the kolpos to redefine the waist, high or low.
