Witherspoon’s classic look featured gold coin-shaped buttons running down the middle from top to bottom.

She paired the timeless ensemble with a pair of black Christian Louboutin pointy heels.

The Hollywood staple showed off a nude manicure and adorned her fingers with several rings.

For the special occasion, Reese parted her blonde locks to the side and styled a chic updo.

Her shiny locks were swept back in a neat, low ponytail that floated down her back in loose coils.

The style allowed her to show off her dainty and dazzling diamond teardrop earrings.

The Sweet Home Alabama actress put on a brilliant display with a full face of flattering makeup.

Her big blue eyes popped with fluttering lashes and her cheeks were dusted with a rosy-tan shade.

Reese finished with a hydrating pink lip stain while smiling for the photos in the step-and-replay.

The entertainer was joined by Riley Keough, 33, and Sam Claflin, 36, on the red carpet.

Riley, the star of the ’70s-based TV show, looked incredible when she attended the event just weeks after mother Lisa Marie Presley’s death.

The Girlfriend Experience actress rocked a low-cut black dress with a sparkly textured black skirt and black opera gloves.

The Zola star donned large statement earrings with large emerald stones and gold hardware.

Sam looked handsome in a cherry-colored suit and a low-cut, fitted black crew-neck shirt tucked into his pants.

He added black dress shoes and sported a full beard with his dark hair slightly tousled.

The Prime Video series follows the rise of rock band Daisy Jones and The Six through the Los Angeles music scene of the 1970s in their quest for global icon status.

Keough recently spoke about playing a musician for the first time and his family’s legacy in an interview with Eastern Time.

She shared that she and her co-star Claflin were musical newbies who are now putting out an album for the series, based on Taylor Jenkins Reid’s book of the same name.

The fictional band, made up of Keough, Claflin, Suki Waterhouse, Will Harrison, Josh Whitehouse and Sebastian Chacon, performed 24 original songs for a new album titled Aurora, which will debut on March 3 alongside Prime Video.

When asked if he feels this show is a way to carry on his family’s musical legacy, Keough didn’t see it that way.

‘I certainly wouldn’t put that pressure on it. I don’t know if my grandfather’s legacy continues, it’s something of my own. But it was a really fun experience for me,” Riley shared.
