The Ionian Chiton was similar to the Dorian, but it was lighter, thinner, and designed to be worn with outer garments. While the Dorian Chiton was wool, the Ionian was linen. The extra flap at the top was unnecessary since there were other layers to put on top, so the piece of linen didn't have to be so wide. The open vertical side was sewn shut and stitches or brooches along the shoulders and top of the arms replaced the pins and formed sleeves.
The accompanying picture shows the chiton worn alone. This is unusual, but the scene shows a woman attaching the girdle (belt that looks like a length of rope), so she hasn't finished getting dressed.
She might have worn a Dorian Chiton on top of this Ionian Chiton or she might have worn the cloth of a Dorian Chiton as a mantle -- or both. How the mantle was worn varied with the fashions. It served as a protective outer garment and was usually preferred as head covering to a hat, although clearly women had hats.
