Will Breast Implants Ruin a Tattoo on Upper Rib Cage?

You should definitely wait.  You want to know exactly how you will look before you get a ta too.  The breast augmentation will most likely cause the skin to stretch and can in turn make your tattoo look distorted.  It is primarily your decision but I think if you are going to make such an investment in your body, you will want the best results possible. Good Luck!

If you have your heart set on having breast augmentation soon, I would suggest that you postpone the tattooing. Any area of nonhealing or infection associated with the tattooing process may necessitate postponement of your breast surgery.  Also, having breast augmentation surgery performed first will allow you to appropriately plan positioning and design of the tattoo.
