Jackie Bouvier and John F. Kennedy were married on September 12, 1953, in Newport, Rhode Island, in front of some 700 wedding guests.
A dapper JFK in a morning coat, and Jackie looking radiant in her now-iconic wedding dress—which, it turns out, she hated.
According to Time, the 24-year-old bride—"already a tastemaker with a reputation for devil-may-care chic'"—wanted an unfussy dress with sleek lines. Instead, she "bowed to family pressure to wear something more traditional, despite thinking it looked like a lampshade."
The "lampshade" dress and its 50 yards of ivory silk taffeta almost didn't see the light of day when a pipe burst in designer Ann Lowe's New York studio a week before Jackie and JFK's nuptials. The dress—which had originally taken eight weeks to cut and sew—was re-created by the designer and her team just in time for the wedding. special occasions wears for cocktail party
Talk about pre-wedding stress.
