From Hope's "Costume of the Ancients."
With the Greeks the tunic was the principal article of attire. It was worn next to the skin, and was of a light tissue. In the earlier time it was composed of wool, in later periods of flax, and in the latest periods it was either of flax mixed with silk or of pure silk. The illustration given will serve to show its construction. It was a simple square bag, open at the two ends, made sufficiently wide to admit of the folds being ample, and sufficiently long to allow of its being gathered up about the waist and breasts. It was kept in its place by various means, either by a simple girdle round the waist or by cords drawn crosswise between the breasts, over the shoulders, looped at the back, and again drawn round the waist, or by an arrangement of cords or ribbons drawn over each shoulder and attached to the girdle.
