remove green screen from background only while person clothed green

@Shebbe has the common approach to fixing this issue in post.

You could try exporting an Image Sequence to Photoshop and then use Select Subject followed by Add Layer Mask via a Batch Action, cleaning up the resulting Layers Masks as needed.  Use PSD as the file format to be able to easily save the results on the Photoshop side.  I’ve saved some shots of actors in green Army uniforms that should have been shot over bluescreen with this approach.

No, you will have to do the keying process as usual. Then on top you have to add a copy of the footage and rotoscope the pieces of clothting that should remain visible. Depending on the complexity of the footage/acting you may find it easier to do that task in After Effects. I'd even say do it in Mocha if you are familiar with it as it's a much faster way to do these tasks. Mocha AE is free and integrated by default in AE.
