Fashion victims of the ancient world

Here's how Herodotus (a Greek historian of the fifth century BC) sums up the Persian penchant for adopting other people's customs:

The Persians welcome foreign customs more than any other people. For instance, they decided that Median dress was more beautiful than their own, and so they wear it. They wear Egyptian breastplates for their wars. Whenever they learn of employments of all sorts, the adopt them for their own practice. From the Greeks they have learned to lie with boys. (Book I, sec. 135, translation by David Grene)
