Arcane Topic Warning: Part the Second

That is, running around upright with clothes on does not necessarily mean you've got a soul

However, what sort of clothes would they have? Most likely 'raw' ones (furs maybe), differentiating these outcasts little from other animals. I also think that their outcast status impacted on how they behaved; regardless of their clothes, they must have been wild in manners and appearance. And they attacked by night, which also tends to enhance (phisically and morally) the ugly parts of what the elves would perceive about them.
