Zendaya — The Light-Up Cinderella Dress (2019 Met Gala)

Zendaya arrived at the 2019 Met Gala in a Tommy Hilfiger gown that her stylist Law Roach activated with a wand — the dress literally lit up, changing from dark grey to glowing blue like Cinderella's transformation. It was the first tech-integrated red carpet look that actually worked as both fashion and theater. The video was viewed 100+ million times. Law Roach and Zendaya have since become the most influential stylist-client duo in fashion. She was 22 years old. The moment cemented Zendaya as a fashion icon before she'd even won her first Emmy.
