There’s a lot of thought that goes into getting a tattoo: Which artist should you trust? What design do you want? Where will you get inked? More difficult than thinking up a solo piece of body art, though, is getting a matching one with your significant other. Because if a relationship is going to last forever — it better look pretty damn good, right? Luckily, there are ways to ensure your couple tattoo looks cool enough to stand the test of time.
