Leaving behind a successful acting career, Grace Kelly married Monaco's Prince Rainer III in April 1956. The antique Valenciennes rose point lace decorated upper bodice, high-necked, long-sleeved wedding dress, designed by Helen Rose was worked on by 36 seamstresses for 6 weeks. Grace Kelly really looked princess-y on the fairytale wedding day and had since become a great inspiration to modern brides.
