| I'm thinking about doing the same thing.  I have a black sun tattooed on the left side of my chest.  I was thinking about making the inverse on a shirt that aligns with the tattoo, except the tattoo on the shirt would be white.
 Another thing I was thinking about.  What if you did it the negative?  I mean cover a design on the fabric and bleach the rest of the shirt?  This would give you choices of color instead of just white on black.  You could take a red shirt, cover a heart-shape in the front, and bleach the rest white.
