Kourtney Kardashian and Travis Barker kept things classic for their debut on the Oscars red carpet.

The couple wore black from head to toe as they arrived at the Dolby Theatre in Los Angeles on Sunday night.

Kardashian sported a strapless black Thierry Mugler gown and wore her hair slicked back for Hollywood's biggest night. Kardashian's Mugler dress was a vintage design from the 1980s, according to E!

She kept her jewelry simple, only accessorizing with diamond earrings.

Barker — who is performing at the show — opted for an all-black suit for his Academy Awards debut. He accessorized with a silver pin and black sunglasses.

As always, the engaged couple were happy to pack on the PDA as they held hands and kissed for the cameras.

Before she made her red-carpet arrival, Kardashian shared a video of herself getting a facial on her Instagram story.

"A little Oscars prep," she said in the clip, tagging renowned celebrity esthetician Iván Pol.
