The pink suit's first major public appearance was on in March 26, 1962 in London. Jackie wore the suit and the matching pillbox hat as she and her sister Lee Radziwill arrived in London after their famous trip to India. She stayed at her sister Lee's house and had lunch with Queen Elizabeth II on March 28.
