Speaking of Quark, I've always wondered why he (and some other Ferengi) do not wear that head dress thing. I've only seen bits an pieces of them in TNG so I don't know if it was ever explained there or ever explained at all.
Does the head dress mean anything in particular to the Ferengi or is just a fashion statement, like how some people like wearing ball caps and others do not.
The real world reason was that most Ferengi masks didn't wrap all the way around the back of the head, and the dress was used to cover that up and make the makeup process easier. Quark was the first, and one of the few, Ferengi that had the full mask.
