Good place for my newest/last tattoo?

I currently have 3 tattos. I have Bullet Proof on the inside of my right foot, a heart formed by symbolic words on my lower back, and a crab holder my uncles name that ped away from cancer on like the left side of my back close to my rib cage. I want to get a locket to symbolize my soon to be husband and I. No names involved. Any ideas for locations. And if your answer includes to not do it or its trashy then don't respond...everyone has their own opinion and my question has nothing to do with your opinion on if I should get it
