Diana paired it with sheer tights, statement pearls and her natural radiance, creating a look that was both glamorous and defiant.

But it was the timing that made the dress historic. On the very night Diana stepped out at the Serpentine Gallery, the then Prince Charles publicly admitted his infidelity in a televised interview.

Instead of retreating from the spotlight, Diana arrived looking radiant, self-assured and unapologetically stylish.

The image of her walking past cameras in that black dress instantly dominated headlines around the world.

The “revenge dress” has since been credited with revolutionising the way women view the little black dress. What was once considered a safe, classic staple became a statement of empowerment.

Diana showed the world that the LBD could be bold, sexy and symbolic - a canvas for confidence as much as for fashion, not just a staple to be kept for respectful events or mourning.

Decades later, the legacy of that dress continues, and her two daughters-in-law, the Princess of Wales and Meghan Markle, have both embraced the trend, keeping Diana’s influence alive in royal fashion.

The pair have adopted the little black dress as a powerful wardrobe weapon.

Princess Kate, 43, has often turned to sleek black gowns for her most high-profile appearances, favouring off-the-shoulder necklines, figure-flattering cuts and bold jewellery that echo Diana’s fearless choice back in 1994.

Her look at the 2022 Top Gun: Maverick premiere, where she stunned in a dramatic Roland Mouret black gown alongside Prince William, was hailed as one of her most glamorous appearances to date - and a move that carried clear shades of Diana’s confidence.

Meanwhile, across the Atlantic, Meghan, 44, has also made the LBD one of her signature looks.

She frequently steps out in striking off-the-shoulder designs for evening galas and has shown how the style remains both versatile and symbolic. Just like Diana, she has used fashion to make subtle statements about independence, modernity and strength.
