The Locrian Code

One of the earliest sumptuary laws is credited to Zaleucus, a 7th century BCE Greek lawgiver in Locri, Italy. It concerns the behavior of women and the dress of both sexes:

…no free woman should be allowed any more than one maid to follow her, unless she was drunk; nor was to stir out of the city by night, wear jewels of gold about her, or go in an embroidered robe, unless she was a professed and public prostitute; that, bravos excepted, no man was to wear a gold ring, nor be seen in one of those effeminate robes woven in the city of Miletus.
