Euphoria star walked the red (and white and blue) red carpet at her first Met Gala in a darkly sophisticated Old Hollywood look: sleek hair waves, a diamond choker, and crimson lipstick. The sheer dress is definitely grown up, but the embellishments keep it from being too revealing. It's seductive, but probably still a lot more comfortable than some of the naked dresses we've seen at the event. It's no surprise that Apatow wore black.
