DIY Cut Out Skully Tee (or Halloween Costume that could go horribly wrong). Tutorial from Cut Out and Keep here. The picture above is a version of this project. The original is a skull cut out on the back of the Tee. MardyBum’s Tee (pictured above) is posted here - and understandably has generated lots of comments about it being a “different type of shirt” if it had been cut higher. So I guess it depends what kind of costume or skull shirt you want it to be!
