Problem with clothing on character

In my application user can wear different clothes. Clothes for character are skinned meshes with bones, identical to character's bones. Clothes should dress on a character through attaching clothes bones to character's bones. The problem is that bones are attached, but clothes mesh worn “unevenly”, some parts of character's body get off from clothes (see pic.1). Dressing should be processed at run-time, clothes are load from asset bundles. Please, see my code.

Start Download() function: function StartDownload () { if (url.IndexOf ("file://") == 0 || url.IndexOf ("http://") == 0) { download = new WWW (url); } yield download; assetBundle = download.assetBundle;

 if (assetBundle != null)
 {
     loadedObject = assetBundle.mainAsset;
         
     if (loadedObject != null) 
     {
     instanced = Instantiate(loadedObject);
     // get all components of instanced object
     numT = instanced.GetComponentsInChildren(Transform);
     // get mesh from array of components
     objectMesh = getMesh(numT);
     // get link on SkinnedMeshRenderer
     skm = objectMesh.GetComponent("SkinnedMeshRenderer") as SkinnedMeshRenderer;
     // get link on sharedMesh from SkinnedMeshRenderer
     m = skm.sharedMesh;
     // add mesh filter
     objectMeshFilter = GameObject.Find(objectMesh.name).AddComponent(MeshFilter);
     // add current clothes mesh to mesh filter
     objectMeshFilter.mesh = m;
     // wear current clothes on girl
     wearing();
     // destroy instanced object
     Destroy(instanced);
     }
     else
         Debug.Log("Couldnt load resource");    
         }
 else
 {
     Debug.Log("Couldnt load resource");    
 }}

Wearing() function:

function wearing() {
        bonesArr = new Transform [numT.length-1];
        // we start at [1] because transform of game object itself is at [0] position
        for (i=1;i
  
    it is a mesh
        if (bonesArr[b].renderer != null) {
        // bind mesh to root bone 
        bonesArr[b].transform.parent = girl.Find("root").transform;
        bonesArr[b].transform.position = girl.Find("root").transform.position;
        }
        // change names of attched clothes bones 
        if (bonesArr[b].renderer == null) {
        // gameObject doesnt contain mesh -> it is a bone
        bonesArr[b].name = bonesArr[b].name + objectMesh.name;
        }
        }
}
