A 'horrendous occasion': Charles told Diana before their first joint public engagement

In a recording sent to journalist Andrew Morton, Princess Diana described how she was mortified by the reaction to her first public engagement. Diana wore a black taffeta gown to a black-tie event at Goldsmith's Hall, which Prince Charles didn't like as black is only worn by royals in mourning. The future princess was starstruck when she met Princess Grace of Monaco who told her: ‘It will only get worse.’.
