Creating a clipping mask over a low-opacity layer
I have a layer set at 50%, and a layer above it that I have set as a clipping mask for it -- unfortunately I can't figure out how to keep the clipping mask layer from being affected by the low opacity layer. Here are a couple picture of what I'm talking about.


I just want to keep the pattern of the transparent shirt attached to it, so that when I am drawing the pattern it doesn't go outside of the shirt, if that makes sense. I have tried layer masks, blending options, linking the layers, adjustment layers... but maybe I'm not doing something right. I mainly only use Photoshop for painting so I'm not too adept with all the tools.
So is there a way to keep the pattern locked into the base color of the shirt and not have it be affected by the opacity?
Thank in advance!
