What's a good place to get a tattoo?

I just recently decided that I want a tattoo when I'm older and I think I've found a design I really like. My only problem is that I don't want to have it somewhere that is easily seen. Like I don't want it on my arms or neck or anything like that. I thought about getting it on my shoulder, but I couldn't be able to wear a tank top. It's not that I *have* to hide it, it's just for respect reasons. I plan on be a business major later, and I'm a little superstitious about having tattoos. Anyway, are there any places that you think would be easily hidden, like even in summer time? Obviously I realize that I won't be able to hide it in every situation, like if I wear a swimsuit or something, but I want to be able to hide it with at least a tank top. I'm think lower back, but would that be weird? Idk
