Cut numbers-related question

Hi, consumersimmer
The item you cloned, yfBody_SP04LlamaGirl, is made of 5 meshgroups. Your blend file contains 3 and this is done in the wrong way. Once you import the blend, only some meshgroups are replaced

- open your blend file, delete two other meshgroups, leaving only the one with 0000 cut;
- clone yfBody_DressPanels, import your blend there;
- this item contains one meshgroup in all lods but LOD1, so do the same thing to all other lods but LOD1;
- as for LOD1, export this blend from yfBody_DressPanels, open. You will see 2 meshgroups: a piece of the skirt and the rest of the item, delete both. Append your dress in the scene, separate a front piece of the skirt like it was in the original, not any other part of the garment. Give it 0001 cut. Save, import back

You replaced only the diffuse map, other maps are still the same. You need to either remove them or make proper ones
Also, this happens because the belt is vertex painted with 007F00. It should be the same as the rest of the skirt. You should separate the dress, then separate this belt, then transfer vertex paint from the dress to the belt
