Which Area Is Better For Me To Get Tatted Up? [POLL]

I have been due for many upgrades in my life and getting tatted would be one of them. I discussed what I wanted with my friend Joe who will be giving me the thrill of a lifetime. There is just one problem I can't seem to resolve, which is where I should have it done on my body. I always think about the pros and cons about where I would want my tattoo on my body. I would want it below my collar bone on my chest and not together, seperated but just think if I would look tacky for a formal event. The next spot would be my back but heard it is very painful. Last pick would be my left leg around the ankle area since it can always be covered but already have a tat on my right leg. Take the poll below on whether I should get tatted on my chest, back or left leg.
