TRICK or TREAT: Beyonce, Jay Z and daughter Blue Ivy turned themselves into living dolls ‘Black Barbie’ to mark signature

Beyonce flaunts her figure in a skimpy swimsuit and fluffy hot pink parka as she dresses as the iconic Barbie doll for a Halloween night out with Ken Jay Z and Blue Ivy.

Already triumphant in the eerie holiday with their Salt N Pepper costumes, the first family of hip hop went all out for the official day.

On Monday evening, Beyonce, Jay Z, and their daughter Blue Ivy transformed into living puppets in SoHo alongside Kelly Rowland to celebrate Halloween.

The 35-year-old vocalist and her spouse arrived in boxes bearing Beyonce’s ‘Black Barbie’ inscription, while their four-year-old child was attired in a whimsical fashion twist.

'Black Barbie': Beyonce was the perfect vintage doll, showing off her ample assets as she wore the black and white striped bathing suit worn by the doll back in the 650s

By donning the black and white striped bathing suit originally designed for the doll in the ‘650s,’ Beyonce exhibited her considerable physical prowess, making her the epitome of vintage Barbie.

It was a family affair: her husband Jay Z, or Ken as he was attired that evening, and their four-year-old daughter Blue Ivy accompanied her.

Beyonce embodied the quintessential vintage Barbie in the doll’s black and white striped swimsuit from the 1950s.

Designed to cling snugly to the star’s midriff, the swimsuit produced the ideal Barbie curves.

Beyonce matched the doll’s trappings by donning a fur coat, black pumps, and Sunday Somewhere cat-eye sunglasses, all of which she wore after removing the packaging.

While Jay Z wore a prosthesis to achieve a full head of hair for the ‘Black Collector Edition’.

An additional silver cummerbund and bow tie completed the rapper’s ensemble.

Blue Ivy, meanwhile, was attired in aesthetics reminiscent of Barbie. She wore a sequined pink skirt adorned with sequins, an LED light-up POP shoe (designed by graphic artist Matthew Langille), and a leather jacket adorned with hand-painted Barbies.
