But the Greeks and Romans tended to wear a "one piece" garment such as a chiton Hamish, rather than a separate kilt-like garment, nor were they pleated.

It could have additional decoration on top, especially in military situations such as leather thongs hanging from a belt.

I can't say that a mini kilt would not suit any guy whatsoever but I am not sure that I have yet seen one that does. Perhaps it's one of those situations where a tartan doesn't help and where a plain colour would look better.
