The Retro Secret Behind Kendall Jenner’s 21st Birthday Dress

The model was inspired by another reality star's look...

It sounds like Kendall Jenner’s 21st birthday was pretty raucous.

The Keeping Up With The Kardashians lady celebrated in LA on Wednesday night, with family including sisters Kylie Jenner and Khloe and Kourtney Kardashian in tow.

Kendall looked in-SANE in a party-perfect sparkling slip dress, which was designed by Antoine Salameh under his brand LaBourjoisie and in collaboration with her stylist Monica Rose.

The mini was covered in Swarovski crystals and had been custom-made for Kendall. However, she’d actually been inspired by another reality star.

Yep. The design was a dead-ringer for the dress Paris Hilton wore for her 21st back in 2002, which Kendall made a nod to when she captioned an Instagram photo yesterday: ‘Vintage Paris Hilton vibes. 21 21.’

Seems it’s pretty timeless, eh? But while Kendall stunned at her bash, we don’t think she’ll have been feeling quite so fresh the next day.

Khloe, 32, appeared on US chat show Jimmy Kimmel yesterday, where she revealed that Kendall had been a little on the tipsy side.

Talking about an insane prezzie the supermodel had received, Khloe said: ‘We go outside and there’s a guy with a Rolls Royce. We’re like: “What’s the gift, the guy or the Rolls?”

‘And then the guy just hands her the keys to this car. We don’t know who this guy is, he’s some prince.

‘I was like: “Is this a joke?” I think on my 21st birthday I got, like, a dinner and a purse or something.’

While we’d probably fall over in shock at being presented with such an insanely lavish gift, Kendall actually, er, managed to forget about it.

Khloe continued: ‘This morning I was like: ‘Holy crap”. I was like: “That’s so cool, you got this car, how did you get it home?”

‘She was like: “Oh my God, I forgot I got a car last night.” That’s how drunk she was. She was so drunk on her 21st birthday.

‘I really thought it was something totally made up because I’ve never seen something like that before.’

Us neither, Khlo…
