For tattoos that extensive if it were me I'd wear a painted body stocking. That way it's reusable and once you paint it the first time you don't have to sit through painting it every morning of an event. From experience body painting takes forever, and while I did full-body I'd imagine precise detail painting can take just as long if not longer.
Other than that my only thought is to make a stencil that you can tape to the body for the torso parts. Wrapping stripes along arms/legs isn't too tough to freehand if you just lightly block it out first.
