Maybe blondes do have more fun.

At least, that seemed to be the case for Kendall Jenner, who transformed into Hollywood's most famous blonde bombshells: Marilyn Monroe. The Kardashians star kicked off the Halloween 2023 festivities early, dressing up as the late legendary actress in one of her iconic off-duty looks.

To channel the screen siren, Kendall debuted a head-turning blonde hair transformation, rocking Marilyn's signature pinup curls and deep side part. The supermodel completed her costume with a black long-sleeve turtleneck and white curve-hugging pants. She paired the timeless ensemble with diamond drop earrings, a dagger-sharp cat-eye and soft nude lips. (See every epic Kardashian-Jenner Halloween costume here.)

While many stars have referenced Marilyn's glitzy and glamorous designs from her films or red carpet appearances, Kendall replicated a more intimate getup—a 1953 photo session with photographer Alfred Eisenstaedt at her home in Brentwood.

However, Kendall referenced a different iconic moment with her Instagram caption, writing on her Oct. 29 post, "Happy birthday mister president."
