More than 20 years ago at the 1996 Met Gala, Diana wore a dark navy Dior slip dress with lace trim that only accentuated the dress's spaghetti-strap design. The lingerie-inspired look was from John Galliano's first couture Dior collection, but Diana made it her own by pairing it with a chunky pearl and sapphire choker.
As fashionistas know well, Met Gala events are themed. The year Diana attended was a tribute to Christian Dior, so her look was extremely fitting.
Maybe this year will bring Kate Middleton or Meghan Markle to the Met Gala carpet?
Perhaps not, with the new royal baby and wedding keeping them busy, but we'd take any of the practically royal stars who have yet to attend too—because seriously, how has Meryl Streep not gone yet?
