Idd, its a shame that most leather sets are so boring or dont fit rogues at all.

Some blue shoulders could work with ur set

If you don't know a white belt, look up the Ghostwalker or Boneshredder belts. Both same model, and the ones for your mog set.

Also, someone else had posted on WoWhead they put on a white swashbuckler shirt to cover their upper arms and such. just a thought. Nice lookin mog tho.

Overall 8/10, not a big fan of goblins :3

Here's my updated rogue.
