I don't know where to put my tattoo?

So. I'm going to get a tattoo of a four leaf clover, but I'm not sure where I want it. It would be my 16th birthday present from my mom. I want it in a sexy spot so when you see it, you know your getting lucky. I was thinking either on my inner hip, or below my breast (like Miley Cyrus?). Opinions? :)
