The 2021 Brit Awards brought together several celebrities who showed up in high style.

The annual affair, usually held in February, is held to celebrate and honor the best in British and international music.

This year's fete served as the United Kingdom's first major indoor live music event since the global pandemic, and there were over 4,000 people in attendance with no face masks or social distancing required. Each attendee did have to take before and after COVID-19 tests.

There were standout looks from some of today's biggest stars, including Taylor Swift, Harry Styles, Dua Lipa and several others.

Ahead, see some of the most swoon-worthy style moments.
