Armpit weight transfer and Strange body shape

Hi. When transferring weights in 2.76-2.79 versions of blender one must do 2 extra steps: first you use Clean tool with All groups selected, then Limit total with 4


Few more things:
- you need to re-transfer uv_1 with Nearest face interpolated;

- delete all areas of the tank top that are covered by the sweater, they serve no purpose, only increase the polycount
- it is best to not use MD's automatic retopology tool, it only makes it worse. See all those triangles along the borders of patterns? That does nothing but increases the polycount. Instead in MD model in quads or retopologize the mesh;
