Princess Diana's stylish niece looked next level when she attended the DKMS London Gala 2024 at The Natural History Museum on Thursday.
The daughter of Earl Spencer, 33, was spotted walking the red carpet in a black dress with a perfect 1950s silhouette - a form-fitting bodice, belted waistline, and full tulle-lined skirt.
