Princess Diana left behind a legacy of iconic fashion moments in the years following her tragic death in 1997. Among some of the best pieces in her royal wardrobe, Diana styled a number of elegant, sophisticated and modern looks for the annual Trooping the Colour event that takes place in the U.K. every summer.

In the years since her death, Princess Diana’s indelible impact on fashion and style maintained consistent interest. So much so that Julien’s most recent auction in May centered the late Princess of Wales. “Princess Diana’s Style & a Royal Collection” auction featured memorable pieces from the late royal’s wardrobe, including her iconic red nylon ski outfit, custom-made pieces by Gianni Versace and her floral “caring dress.”

Ahead, see the evolution of Princess Diana’s Trooping the Colour looks through the years — from the early 1980s to the early 1990s.

Princess Diana attended her first Trooping the Colour event in 1981 just weeks before her wedding to Prince Charles. For the occasion, the then-Lady Diana fashioned a Bill Pashley outfit with a matching hat in hues of light blue. Her hat featured a birdcage veil and her Pashley dress included a statement, flowing white collar. The pale dress also featured hints of pink, and Diana coordinated the soft aesthetic with a pair of white gloves.

As the ’80s continued, Diana’s sense of style and confidence in her fashion choices developed. By 1985, Diana wore sophisticated looks that were emblematic of a modern monarchy. The late Princess of Wales wore this coral-colored dress by Jan Van Velden for Trooping the Colour in 1985, which featured a pussy bow and high neckline. She coordinated her look with a complementary hat and accessorized with pearls.

In the late ’80s, Princess Diana fashioned a look by one of her favorite designers for the Trooping the Colour parade. The royal wore this green and white dress by Catherine Walker with a coordinated hat. This was also the year of a young Prince Harry’s infamous cheeky streak. His little outfit also coordinated with his mother’s attire.
