[Problem with Armature Binding in Blender (2)]

Greetings.

I now have the Avastar 2. The rigging panel looks a bit different from the previous version I've used and now it's confusing for me. 

After binding to amarture, the shorts just don't fit the thighs and they go sideways (attached please find the images of the problems);

Help is very much appreciated. Thanks!

[Problem with Armature Binding in Blender]

Greetings.

When binding my mesh shorts to the armature, the mesh shorts seem to be deformed around the waist part of the shorts (refer to attached pictures).

However when binding the same mesh shorts to other armature (of another mesh body), this doesn't happen.

Any idea why this would happen? I'm new in Blender so a detailed guide/explanation is much appreciated.

Thanks!

When I'm on voice the word "heard" keeps popping out in nearby chat. I have tried adjusting the setting (Phoenix Firestorm viewer) but it still happens.

I don't want the word keeps appearing in local chat while I'm using voice. Can anybody help me solve this? Thanks!
