Well, it takes up to 3 weeks for the crust to come off. Once it comes off, it's not too pretty. :) the skin is red and in some cases, raised and still very sore. The cherry blossom flower I had done 2 months ago is still very red, raised and hurts! This can last up to 6 months.
For a temporary fix, I would go with a professional make-up coverage. For a more permanent solution later on (after the big day), you can look into the rejuvi method or even laser. You mentioned it was black and that is the easiest color to remove by laser, plus less scarring. My tattoo is huge and full of color. Laser did not work for me, so I am going the rejuvi way!
Good luck! And congrats on your big day. Hope it's a special one!
