Mesh not aligned with diffuse?

Hi. The uvs for different frames actually differs a bit, especially in the stomach area. I'll try to find the feminine frame one in the game files but if you'll see the reply sooner, do this:
- expand the rig, make "bottom" selectable (cursor icon);

- select "bottom", shift-select your garment, select uv_0, select all uvs in uv editor with A, remove the image from the background;
- view-draw other objects ( unlike what you're seeing in the pic, there should be no image in the background)
