Adding a second mesh to armature not working

Have a rigged girl from make a human & am now tring to add clothes to the mesh but they keep deforming & wont work with the armature. the shorts I created tend to turn themselves inside out, am I missing somthing that the clothes wont join smoothly to the armature.Any ideas?

What version of Blender are you using?

Do the shorts turn over when you first attach them to the armature, or do you have to pose the armature’s bones first?

When you parent the armature/apply the armature modifier, are the armature bones in their rest position (Alt-G, Alt-R, Alt-S)?

Hmm, I can’t think of anything else right now. If none of these are the problem post a blend.
