Kate Beckinsale went for a daring look for Paris Hilton's Slivmas Party.
The "Underworld" star showcased her toned physique in a racy sheer dress, as seen photos shared on her Instagram.
"When @parishilton says 'dress festive' for her #Slivmas party (to celebrate the release of 'Paris in Love' Season 2 Now streaming on Peacock) you must obey [heart emoji]," Beckinsale wrote as a caption.
"Queen of pink rules [heart emoji]," she added, before addressing the fluffy white cat that joined her in the shoot. "I especially like that in the first picture, the cat, the handbag and I have all achieved the same expression."
The 50-year-old actress looked sensational in her see-through gown, which People identified as a dress from the brand Afffair. It featured strategically placed silver palettes and other metallic embellishments.
Beckinsale ditched her bra for the look, only wearing a pair of lilac briefs under the dress.
To complement the outfit, Beckinsale wore a silver choker and statement earrings, along with sky-high platform heels and a cat-shaped handbag.
According to her post, her glamorous makeup was done by Jose Corella. The actress wore her chestnut tresses pulled back in a stylish ponytail.
Beckinsale also served a fashion moment with the help of Afffair during New York Fashion Week in September.
At the time, the actress showed off her look in an Instagram clip, which saw her dancing to "Shake Ya Tailfeather" in a sheer dress with metallic embellishments, blue undergarments, and a pair of towering heels.
