Princess Diana wore this playful skirt trend in Cannes in 1987 – which will be trendy in summer 2025

Princess Diana wore this playful look in Cannes in 1987.

Like it or not, some celebrity looks have become indelibly etched in the fashion memory. Marilyn Monroe's white, blown-with-the-wind gown or Rihanna's iconic yellow Met Gala gown from 2015 are just two examples. Another look that's repeatedly referenced on the red carpet? The light blue Catherine Walker dress, complete with matching chiffon scarf, that Princess Diana wore to the 1987 Cannes Film Festival. (It seems Lily-Rose Depp, Laura Harrier, and Elle Fanning have all been inspired by it over the years.)

While this dress is one of the late princess's most famous outfits, she was also photographed wearing another ensemble during the same Cannes visit - a look that reveals her fashion sense and shows that she was always one step ahead.

Diana's double-breasted blazer and balloon-style skirt were a prime example of '80s power dressing—at the same time, with its nautical stripes and two-tone pumps, the outfit was perfectly suited to the French Riviera. This outfit, too, was designed by her favorite designer, Catherine Walker, and overshadowed every minimalist trend.
