Bethenny Frankel rang in her 55th year with a blonde bob as she partied the night away with multiple outfit changes into various tiny slip dresses – just weeks after she showed off her shockingly fit physique in a skimpy Halloween costume.

Frankel, whose birthday was on November 4, finally celebrated the big day this weekend with a bash at ZZ’s Club in Miami. 

The former Real Housewives of New York star recently made the move to the Sunshine State over the summer.

When it came to her look for the party, she channeled actress Michelle Pfeiffer in the movie Scarface.

In the film, Pfeiffer plays Elvira Hancock, who Frankel chose to take some inspiration from for her birthday party look.

Frankel wore a sleek, honey-blonde wig with bangs inspired by Elvira, which was made for her by Miami-based hairstylist Leah Caso.

And just like Elvira’s character in the movie, the Skinnygirl founder rocked a long, emerald-green slip dress with a revealing V-neck and slits throughout the skirt.

It was Elvira’s most famous look from the movie.

But that wasn’t all – she had two other outfit changes throughout the night, including a lookalike of the hot pink gown that Elvira wore to the Babylon Club. 

The dress featured a halter-style neckline, a deep V-neck and knotted detailing at the stomach.

And for the finale, Frankel slipped into a black sequined gown with a plunging neckline, channeling Elvira in the Sun Ray Motel scene. 

All of her looks for the evening were designed by Garo Sparo, who was a finalist on season 17 of Project Runway.

Her big bash started out with cocktails and a caviar bar, which was followed by a seated dinner and then dancing with music by DJ ARKiTEKT. 

Among her famous guests was hairstylist Chris Appleton and real estate mogul Ryan Serhant.

Following the party, Frankel posted a few snaps and videos from the night on her social media pages, where many followers couldn’t believe their eyes.

‘Freakin nailed it!’ wrote Real Housewives of New Jersey star Melissa Gorga under one video.

‘I love this hair on you. Wow,’ commented model Heidi Klum.

Former Jersey Shore star Nicole ‘Snooki’ Polizzi typed: ‘This is the look. I watched this 10 times.’

In the past, Frankel has been quite open about her dislike for her own birthday, as it brings up a lot of emotions for her.

She was born on her mother’s 20th birthday, who she had an extremely strained relationship with. The reality star previously revealed that her mom died in April 2024. 

Last year, Frankel opened up about her birthday in an emotional post on Instagram, admitting that the day has always been an ‘incredible source of anxiety’ for her.  

‘Birthdays have always been an incredible source of anxiety. Like Goldilocks, too little was too little and too much was too much,’ Frankel wrote.

‘The biggest trauma in my life was this mother daughter relationship, and we were tethered to one another on this one day. As a child I would get physically sick every year,’ her caption continued.

‘This year, I feel free, lighter, happier as if something has been lifted. It has been profoundly transformative. 

‘I am proud of my age and of the mother, friend, partner and person I am and I am truly happy. I have everything I want and need.’

Frankel’s big birthday bash and dramatic costume changes come just a few weeks after she bared it all on Halloween.

The former Real Housewives of New York star dressed up as a chicken – in a comical nod to her love for chicken salad – for the spooky holiday.

She wore a tight, white bodysuit that showed off her cleavage, along with a pair of thigh-high socks that had chicken feet printed on them.

The daring bodysuit had a thong back, which completely revealed her backside.

Frankel completed her look with a feather headband and a tail, which she pinned to the backside of her bodysuit.

The Skinnygirl founder topped it all off in a pair of sexy, sky-high white heels, as she carried a container of salad topped with chicken in her hands.

Since she’s blown up on social media over the past few years, Frankel has become famous for her chicken salad tasting tests.

She went viral in 2023 for gushing over a $16 chicken salad by Round Swamp Farm in the ritzy Hamptons, and has since tried and reviewed many others on her TikTok account.
