Just one possible idea:
The color for the hoodie itself should probably be black, since black goes with everything, and anything pops off of black. As far as the car (if there is gonna be a car printed on it) maybe that should be black too since black is the most popular (or most common) color.
The background color can be the 'mediation' between the black hoodie and the black car. A red, orange, yellow combo (possibly flames) could be the background.
Just one thought...
