It seems that many people do not know how to correctly mount a tie microphone and run into lots of problems because of this.
The first important point is that you have to decouple the microphone from the cable to prevent any cable noise getting to the microphone itself.
The way to do this is to make a small loop and trap this by the teeth of the tie clip - if the mic. is pointing up, loop the cable up and then down again behind the clothing and trap the cable in the jaws of the crocodile clip (some clips, like the one supplied with the Sennheiser MKE 2, have a special cable slot on the end of the jaws to do this so the cable is not bitten by the teeth). This means that the cable beyond this point is totally decoupled from the mic. itself and any clothing or rubbing noises are not transmitted up the cable to the microphone.
The attached picture shows this - I clipped an MKE 2 to a frosty plastic sheet so you can see the cable both front and back.

If the mic. is pointing down, it's a single loop rather than a doublke loop - but the effect is the same.
This even stops the noises from the steel cable of the MKE 2.
Also - you could tie a loose knot in the cable. Surprisingly this also helps reduce cable noise.
If a tie mic. has to be hidden, the best way is to use Rycote Undercovers or Overcovers. If you use these, I would use two - the first to hold the microphone and a second a little way down the cable to decouple the cable. This does the same job as I described above - any cable beyond the second Undercover/Overcover is effectively isolated from the microphone itself. But make sure the cable between the first and second Stickie is not too tight.
I hope this helps.
