But if you are having a formal wedding or just prefer your grandmother-in-law not know about the giant skull tattoo you have on your back from your renegade days in college - then go ahead and cover. You can choose a dress that will cover over your art. Another way to keep from sacrificing your current fashion choice from your past, is to check out some makeup concealers. The two popular ones I hear about are Dermablend and Covermark. Other popular selections are Secret Camouflage by Laura Mercier and Tattoo Camo.
And as with your makeup and hair, it is always a good idea to test out the product way in advance. Make sure it won't be rubbing off on your dress, the guests you hug or disappear while you bust your moves on the dance floor.
