We are practicing Catholics and marriage is a Sacrament. Our wedding day is November 5th, and my bridesmaid, my grooms sister got..a...big...tattoo...on her BACK!! Now she cannot stand at the altar with us, she cannot go up to receive communion because her back is to everyone and she cannot wear anything that will show the tattoo during the ceremony. Tattoo's are fine with me, but i really didn't want one in my wedding! What should i tell her?!
