The annual Met Gala brought together some of the biggies in entertainment and fashion.

The late German designer Karl Lagerfeld was at the heart of this year's theme.

But a few celebrities' red carpet appearances fell flat.

Jared Leto turned into a massive, blue-eyed Burmese cat mascot.

Pete Davidson chose a slouchy coat with a bucket hat.

Kylie Jenner an off-beat high-slit body-con asymmetric red dress.

Vogue China’s editor-in-chief Margaret Zhang and Olivia Wilde both wore dresses.

Olivia Rodrigo sported a strapless dress with floral accents.

Bradley Cooper decided a plain black suit was enough.

Sydney Sweeney sported a pink Miu Miu dress with a bow at the knee.
