Karlie Kloss is a total knockout at the 2017 Oscars: See her unexpected look!

Karlie Kloss was a total vision at the 2017 Oscars.

The multi-talented model made an unexpected appearance at the 89th Annual Academy Awards at the Dolby Theater on Sunday night, and she looked like a complete knockout in an asymmetrical Stella McCartney white gown.

Kloss, who's currently dating Joshua Kushner (brother of Jared), rocked a floor-length all-white dress with a chic, built-in cape. The dress featured an unexpected twist, though, as the cape only covered one of her shoulders! The other half of her look was totally sleeveless.

The star paired her glam look with an oversized, floral diamond choker and diamond earrings. Her hair and makeup gave off major Old Hollywood vibes -- between her wavy blonde lob and her piercing red lip, we had to double check what year it was!

Her dress was also adorned with a blue ribbon in honor of the ACLU.

Kloss is always a winner on the red carpet, and the 2017 Oscars were no different.
