Sylvester Stallone's 21-Year-Old Daughter SLAYS Halloween As An Infamous French Queen

Scarlet Stallone showcased her sexy Halloween costume on social media!

The youngest daughter of Sylvester Stallone and his wife, Jennifer Flavin, brought some serious heat on Instagram when she shared a series of snaps. Scarlet, 21, went all out on her Halloween costume, which she officially debuted on Instagram on Sunday.

Halloween festivities kicked off over the weekend, and the "Tulsa King" star was among the first celebrities to reveal her costume. Scarlet donned a complete Marie Antoinette ensemble that accentuated her curves to perfection. The baby pink corset dress enhanced her hourglass silhouette as it was cinched tightly on her body.

The piece of clothing crafted of a satin fabric featured white lace trim and pink bows that added sophistication to her scanty outfit.

Scarlet's dress had a neckline that sat low on her chest -- exposing plenty of skin across her décolletage. Its strapless design also helped highlight her toned arms and shoulders.

The body-hugging number also featured a short length that allowed the beauty to flaunt her long, sculpted legs. However, she covered them with white fishnet stockings with small, pink ribbons running up to her thighs. The actress and socialite completed her look with a pair of white stilettos.

For the occasion, Stallone styled her blonde locks in soft waves and pulled them up in a ponytail -- secured it with a white ribbon. She left some tendrils of hair down, which helped frame her face.

Scarlet had a full face of makeup, but unlike Marie Antoinette's glam, hers looked light and glowy.

The first photo saw Scarlet standing in front of a mirror in what looked like a powder room. She popped her hip to the side and placed her hands on her back while slightly twisting her head and gazing into the looking glass.

Scarlet showed details of her accessories, such as bracelets, rings, and a pink feather, in the next picture. A swipe to the right showed the model with her sisters, Sophia, 27, and Sistine, 25, who were also dressed in their costumes. All three were seen huddled in front of a vanity mirror.

The fourth image saw Scarlet crossing the road, followed by her snapping a selfie in the fifth pic.

In the caption, Scarlet wrote one of Marie Antoinette's famous lines: "Let them eat cake."

Legend has it that when told her starving peasant subjects had no bread, Marie-Antoinette, unaware of their struggles, supposedly suggested cake instead, emphasizing a disconnect from the hardships of ordinary people.

Fans showed their love for Scarlet's Halloween costume by showering the post with likes and comments.

"Holy sh*t you're just perfect," wrote one person.

"Prettiest Marie I've ever seen," declared another admirer.

"Omg you look unreal," noted the third user.

Sophia also shared pics from the fun-filled night.

According to her, it was the "first Stallone Halloween party," which "was a success."
