The famous blouse, featured in the February 1981 Vogue magazine, was worn by the late Princess for a photoshoot by Lord Snowdon. This historical garment became a symbol of her engagement and was later worn for various public appearances.
Lord Snowdon's work, including the celebrated portrait, was exhibited at the National Portrait Gallery from July 2007 to 2008 during the 'Diana, Princess of Wales’ exhibit. The portrait was commissioned by Vogue as part of a 'Portrait Portfolio' and coincided with the official announcement of Prince Charles and Lady Diana Spencer's engagement.
The National Portrait Gallery noted, "The publication of this portrait in Vogue magazine in February 1981 coincided with the official announcement of the engagement of Prince Charles and Lady Diana Spencer. Commissioned by Vogue as part of a 'Portrait Portfolio' of young aristocratic women by the photographer Lord Snowdon, it was used by several magazines and newspapers when the engagement was announced."
