That said, you need to re-do certain other things because uv_0 and uv_1 are messed up.
- do not join the body with the garment until the latter received weights, uv_1 and vertex paint;
- the body's uvs must not be scaled or moved. After assigning the template, shrink only the garment's uvs;
- do not scale the garment's uv islands individually unless the difference in quality is acceptable. The geometry that covers holes can be smaller, zippers or buttons can be bigger, the front of the shirt must not be bigger than the back or sleeves;
- try to avoid the bottom right corner of the uv space because people put everything in there and you end up with cas full of items that cannot be used together;
- after transferring uv_1, you're done with uv_1, do not scale it in any way;
- bake textures with bigger margins.

- select your mesh, in uv editor enable sync, select a few faces on body parts' uvs, then press Ctrl L to select them fully, in 3d view press Delete, choose Faces;
- expand the rig, make top visible and selectable;
- select your garment again, add Data transfer modifier. Choose top as Source object. Optionally enable Vertex data, Vertex groups and choose Nearest face interpolated to transfer weights;
- enable Face corner data, UVs, uv_1, Nearest face interpolated to transfer uv_1;
- click on Generate data layers and hit apply;
- if transferred weights, in Edit mode select everything, Tools - Weight tools - Clean with Subset set to All groups, then Limit total;
- select top, in 3d view press Shift D, then Esc to duplicate. In edit mode select everything with A, Tools - Remove doubles with Merge distance set to 0,0001;
- disable Limit selection to visible, select everything covered by the garment. The more you delete, the more space you'll have to put your uvs in. Once done, Delete - Faces;
- in this order: select top.001, then Shift-select your garment, in 3d view join with Ctrl J;
- switch to Edit mode, select everything, choose the background image;
- select all uvs of the garment, UV - Average island scale ( you do this just this time to even them out a bit, from other programs they would come normally sized ). With everything still selected, move until the biggest uv island sits in the biggest free spot, then start scaling down until it fits. Then deselect it and move other islands until they fit;
- dont forget to re-size both specular files. The mask one isnt made correctly currently. You can click on Make blank to see what it is meant to look like
