I'm writing a scene in which I wish to describe a typical street beggar - his way of dressing in particular. Check for example such a dude as the one below

I could use descriptions such as: snobbish, dirty, bizarre, rugged, barbaric, etc but feel those are not adequate to building a picture of a beggar in the minds of my readers. I want words that would describe a sort of beggar that typically, you'd wish to avoid - one very pitiful, but also repugnant?

What words or phrases would you use for such a description?
