+++ You are free, in what you are greating, but this could be a way,
how it can look... +++
Maybe some kind of the typical energydrink-designs/shirts of
"Rockstar", "Monster" etc. - it can be dirty, but it can be clean,
too. Do, what you think, that it looks great.
maybe some crazy animal...
maybe some dancing crowd on a festival...
maybe some cool dj...
Maybe polygol design style...
Or possible ist some kind of "hipster"-design.
It will come on t-shirts and tanktops. It should be wearable for
normal outfits, so that its kind of "cool" for the crazy kinds, but
should fit for wearing in nightclubs and on edm/dubstep/trap-events,
