This is a stye of male fashion I find extremely attractive: not in the usual sense of attractive, as in I want to jump their bones, but rather like I find a pretty forest attractive. The aestethics says something significant about the wearers personality. Exhibitionism for sure, but also a flare for silent drama. All the draping makes me think of wizards in their robes, dangerous and powerful, but the oversized fits suggests vulnerability, a need to hide.
And then again, maybe they just think its cool. I know I do!
