Kim Kardashian turns 44 in barely-there ‘birthday suit’ dress

44 never looked this good.

Kim Kardashian celebrated her birthday a day early — in what she called her “Birthday Suit.”

The reality star showed off her curves in a plunging nude gown by Diesel ($1,650) that features a very Skims-like bodysuit over a shiny sheer tulle skirt on Sunday night.

In a video posted to her Instagram Story, Kardashian showed off her famous curves in a mirror.

And in a close-up photo, she showed off her accessory: a blinged-out cross necklace made of enormous pear-shaped diamonds.

It is unclear where or how exactly the mom of four celebrated, but she did share a pic of her birthday cake, which featured a calendar depicting the month of October with the 21st circled.

Kardashian’s celebration comes one day after she slipped into another curve-hugging look at the Academy Museum Gala, showing up to the star-studded red carpet in a vintage Thierry Mugler ensemble featuring a tiny corset and micro shorts.

The barely-there corset featured a low neckline and exaggerated hips, hailing from the brand’s 1998 couture collection. She paired the head-turning look with a spray of diamonds around her neck, Old Hollywood waves and a floor-length hooded robe.

And she wasn’t the only member of her family to pull from the storied fashion house’s archives; sister Kylie Jenner showed up to the same event in a black and nude sequin gown from the same runway — which occurred just one year after the makeup mogul, 27, was born.

Sister Kendall Jenner, who recently went blond, was also there, wearing a strappy Schiaparelli couture black velvet gown.

We can’t wait to see what the entire Kardashian-Jenner family pulls together to celebrate Kim on Monday.
