The music industry’s biggest stars attended the 66th Grammy Awards in Los Angeles in attire as varied as their songs and albums. Much of that attire — whether it was a cutout gown or a sheer shirt — exposed midsections.

Dua Lipa and Miley Cyrus were two of the many who chose outfits with metallic tones, perhaps in hopes of earning a golden statue to match. Gracie Abrams, Paris Jackson and others opted for black, while Kylie Minogue and Bonnie McKee were among those in red, one of the most popular colors seen on carpets this awards season. (Ms. McKee complemented her red dress with a nest of fiery hair.)

Several of the night’s most memorable looks reminded viewers that there’s nothing wrong with replaying old hits. Laverne Cox, the E! host who interviewed stars on the red carpet, wore a structured Comme des Garçons dress from 2015, and Olivia Rodrigo chose a white Versace gown that is almost 10 years older than she is.

The Grammy Awards are known to be a fashion playground, and this year’s event was no exception. But the following 22 looks (three of which belonged to the members of boygenius) stood out more than most, for better or worse.

Some people saw Cleopatra. Others saw Barbarella, or Princess Leia in her Jabba the Hutt period. Whatever the references, the “Flowers” singer’s metal mesh by Maison Margiela was marvelous.
