Rena Riffel, 57, wears cheetah-print bikini to Hollywood Halloween party

A barely-there cheetah-print bikini was the outfit of choice for Rena Riffel as she departed a private Halloween gathering in Hollywood on October 12. The 57-year-old “Showgirls” actress opted for this daring ensemble over a traditional costume, showcasing her toned physique while walking down the sidewalk in towering heels. Her appearance featured sculpted abs and long legs, projecting confidence despite the late hour.

Hollywood party attire details

Photographed outside the retro, Playboy-themed celebration in California on Monday night, Riffel wore a triangle bikini top with thin straps paired with high-cut string bottoms. The skimpy animal-print two-piece highlighted her defined abs, slender waist, and sculpted legs. She completed the look with black pointed-toe heels, dark sunglasses, and a black choker, while her long blonde hair fell loosely over her shoulders.

In images obtained by MEGA, the star walked along the sidewalk at night, holding a long accessory in one hand and extending her other arm slightly to the side. The photographs captured her bold exit from the event, emphasizing her fit figure against the backdrop of the evening setting.

Back view and tan lines

Riffel turned toward the cameras during her outing, revealing her backside in the cheeky cheetah-print bottoms. The high-cut design exposed much of her toned derrière, while also highlighting noticeable tan lines across her back where another swimsuit had previously covered her skin. Delicate strings tied at the back further accentuated her slender waist and toned upper body.

One shot showed the blonde beauty glancing over her shoulder, flashing a subtle smile behind dark sunglasses while holding a chain-like accessory. Her black high heels added height to her leggy frame as she posed on the sidewalk, appearing unfazed by the attention directed at her age-defying physique.

Past social media appearances

This recent outing follows earlier posts where Riffel displayed similar swimwear choices. On August 9, she shared an Instagram photo from Sorrento, Italy, showing herself in a swimming pool wearing a leopard-print two-piece. The halter-style top and matching string bottoms showcased her slender waist and toned stomach, with her blonde hair styled in a casual updo framing her face.

Captioning the post “Having a beautiful time in Sorrento,” she included Italian-themed emojis and hashtags. Followers responded with compliments such as “Wow–so cool, Rena! You look amazing!” and “FABULOUS.” Another admirer wrote, “So beautiful! Enjoy!”

Additionally, during a summer getaway to Montecito, California, in August 2025, Riffel posted an image of herself in a blue-and-white patterned bikini at the Montecito Inn. The plunging halter top and matching bottoms highlighted her toned stomach and waist as she posed in crystal-clear water.
