I'd also recommend going to swap-meets or antique shops as well, there are lots of tunics that you can swap buttons on and modify! :) And that way you can get that thicker wool feel, like an actual uniform. Wow, I keep prattling on, I'm really sorry, but I'd also recommend actual military/service ties, they have a nicer feel to them and most of them are made out of wool, shiny ones clash a bit with uniforms. ^^ Hope that helps a bit.
