Blackomania or Subculture Within a Culture?

I was always thinking why many of Armenian men like to wear black clothes: black jacket, black shirt, black pants, black shoes, black socks (hopefully not red socks). They wear black all the time, wherever they go, whatever they do. 

Why are they buying only black? Isn’t any other color out there? Don't get me wrong, a man wearing black suggests elegance, authority and power. But when I see groups of people in black who are not going to a funeral, there is something suspicious in it, isn’t it?
