Some families have the grandfather clock.
Others have the set of monogrammed silver. Mary Elizabeth Kelly and her family have The Dress. Over the years, the dress has been dined in and danced in, cuddled in and cried on. It's been tugged at, twirled in, talked about and revered, even sprinkled with holy water. Fifteen times in 52 years, the dress has transformed a girl as she solemnly stepped down a church aisle, rosary beads in hand, a lace veil on her head.
