Kim Kardashian copies Bianca Censori’s style in plunging skin-tight dress as fans are ‘confused’ over odd birthday look

KIM Kardashian appeared to copy Bianca Censori's style in a plunging skin-tight dress, with fans 'confused' over the odd birthday look.

Skims founder Kim, 44, showcased her hourglass figure in a tight nude leotard, layered beneath a semi-transparent PVC dress ahead of her big day last night.

In snaps and videos shared to her Instagram Stories, the reality star zoomed in on herself in a mirror, teasing her followers with the caption: "Birthday Suit."

She layered the clip against Sabrina Carpenter's Bed Chem, posting a close-up of her cleavage in another selfie.

But some of Kim's fans were left scratching their heads over her sexy look.

Taking to a Reddit forum, one asked: "Kim, why?" with another chiming in with: "Kimberly, pls what the hell is this?"

A third questioned: "Why does EVERYTHING have to be so tight, short, small and uncomfortable looking?"

Someone else wrote: "I'm sorry, but that might be the ugliest dress I've ever seen."

Her racy getup also bares striking similarities to something recently worn by Kanye West's new 'wife' Bianca, 29.

Back in June, model Bianca donned a nude one-piece for her attendance at the Prototypes Menswear show during Paris Fashion Week.

Kim's ex-husband Kanye was there too, covering up with a beekeeper outfit for the appearance.

Kim also spent last night flanked by her sisters Kendall and Kylie Jenner as they led the glamour at the Academy Museum Gala.

The Keeping Up With The Kardashians stars couldn't be missed as they rubbed shoulders with the Hollywood elite at the Los Angeles event.

The fourth Academy Museum Gala of its kind - which acts as a huge fundraiser - saw the Hulu stars don lingerie-style gowns.

Kim led the way in a busty white corset top and tiny matching shorts.

A flowing white jacket with ruched sleeves worn over the top added a stylish edge for the business mogul.

She wore her brunette locks in classic waves and accessorised with a sparkling silver necklace, drop earrings and metallic shoes.

Her model sibling Kendall, 28, struck a sophisticated look in a figure-hugging black halterneck gown.

The frock's design featured cut-out panels for a sexy edge and a silver broach.

Kendall - who recently switched up her brunette hairstyle for a golden blonde shade - wore her shoulder length locks in curls.

The Victoria's Secret model posed for a few solo pictures before joining little sister Kylie, 27.

The mom of two opted for more daring attire, with her dress featuring a flesh colored skintight body and black skirt detail.

She styled her hair in natural waves and kept her make-up minimal to vamp up the impact of her look.
