Unseen UVs appear in Texture paint? So through all of the little issues I've been able to find and fix online, this one has be stuck....



????Where are these extra shapes coming from and why can I only see them when I texture paint???? I can't select them through the uv panel or in edit mode. I've searched my mesh for double verts and such...the only thing I can think of was sometime in the past I may have made the faces double sided, the sleeves I think. But why can't I edit the uvs if that is the problem.

Please help I've been stuck on this one all day.

Link to blender file:
You have mesh artifacts and double vertices from modeling in your geometry. 



There are two possibilities to solve this. 


Tab into Edit Mode, hit W and select "Remove Doubles". You need to unwrap your model after that again.
In your UV/Image Editor window, hit A to select everything, turn on "Keep UV and edit mode mesh selection in sync" (see image below), switch to Face Select mode, then select all the faces you want to get rid of. Move your mouse to the 3D View and hit X and select "Faces" to remove them. 




Make sure to check and recalculate the face normals after that.
