Harry Styles attended the Grammy Awards on Sunday, and he made a case for wearing feather boas while there.

He opened the show with a performance of his hit song "Watermelon Sugar," and wore a leather suit with no shirt underneath. He also accessorized with a green feather boa.

Styles wore the scarf wrapped around his neck and later loosened it, revealing that it extended from his shoulders nearly to the floor.

In addition to his Gucci suit and scarf, Styles also wore black shoes with brown heels, and a variety of rings.

Midway through the performance, he ditched the boa completely and showed his full outfit.

Harry Lambert styled the musician for the performance and shared a photo of Styles' outfit on Instagram.

On the red carpet, Styles wore the same boa in a purple shade. That time around, however, he paired the accessory with a yellow, '70s-inspired houndstooth blazer, brown velvet pants, cream-colored shoes, and a pink-hued shirt with a low V-shaped neckline.

Styles is nominated for three awards this year, including best pop solo performance, best pop vocal album, and best music video.
