Greek clothing was sold in the agora, the marketplace. You could buy clothes. But they were expensive. Most families made most or all of their clothes.
Their clothes were simple. They made clothes out of wool for winter wear, and used linen as their summer fabric. They dyed tunics and cloaks in bright colors. They bleached some material to a bright white. Clothes were decorated with geometric designs and could be decorated to represent their city-state. Some clothes were left plain.
The Greeks wore a hat they invented for traveling. It had a chin strap, so it could hang down their back unless they needed it for protection from sunshine or rain.
The rich bought jewelry from traveling peddlers. Everyone made jewelry. It was very popular.
Both men and women used perfume made by boiling flowers and herbs.
