HELP! Hairy situation

Sarah

It’s warm out today so I decided to wear a dress the dress is low in the back. I look in the mirror and I have two dark hair patches on my back that I never noticed. Now I do have two tattoos on my back so I was shaved once (peach fuzz) could it have grown back thick and dark? Does any one else have hair in there back? What do you do? Is it normal?
