DX9 - Using animation from base Mesh (armor by parts)

Hey, Im using directx allocate hierarchy from dx9 to use a skinned mesh system. one mesh will be only the skeleton with all animations others meshes will be armor, head etc, already skinned with skeleton above. No animation, idle position with skin, thats all I want to use the animation from skeleton to other meshes, so this way I can customize character with different head, armor etc. What I was thinking its copy bone matrices from skeleton mesh to others meshes, but Im a bit confused yet what way I can do this. Thanks.
