The perks of having not one, but four sisters is surely being able to share their wardrobe when you’re in need of a killer outfit.

And Kendall Jenner, 25, seems to have done exactly that, as she stepped out in Las Vegas wearing the exact same outfit her younger sister Kylie Jenner, 23, was seen sporting 11 months ago.

Model Kendall took inspiration from her sibling as she slipped into the sultry ensemble that paired together a see-through tube top and matching patterned trousers to attend the grand opening of the Wynn’s new club Delilah.

Kylie, meanwhile, had rocked the stylish outfit, that made sure to show off her enviable physique, nearly a year before when she headed for dinner at Nobu

While Kylie opted for a ɴuᴅᴇ bra underneath the see-through number to cover her modesty and pointed sling-back heels, Kendall cheekily decided to go braless, leaving little to the imagination.

The Keeping Up With The Kardashians star slipped into a pair of white strappy heels and accessorised the look with a mini white handbag.

Kendall seemed to take inspiration from Kylie on the beauty front too, and, like the Kylie Cosmetics CEO did, wore her dark shoulder-length locks down in bouncy waves.

She completed her look with a pair of silver earrings, a glossy burgundy lipstick, heavy hand of blush, bronzer and false eyelashes.

Nearly a year prior, Kylie had teamed the exact same look with a gold cuff on her wrist and wore her light brown tresses in tousled waves.

Kendall was definitely familiar with the eye-catching outfit as she dined with Kylie when the mother-of-one first wore the chic getup out to dinner.

Clearly a fan of her outfit, Kendall made sure to document her outfit all night as she partied away with her best friend Hailey Bieber on Saturday in Sin City.

The pair were also joined by Hailey’s husband Justin Bieber – who had performed on stage earlier that evening – and Kendall’s older sister Kourtney Kardashian, who had touched down in Vegas with new boyfriend Travis Barker.

The star-packed guest list also included power-couple Megan Fox and Machine Gun Kelly, as well as a performance by Andra Day.

Modern Family’s Ariel Winter, Tyga, Urkle actor Jaleel White, singer Anitta, Steve Aoki and The Chainsmoker’s Drew Taggart and Alex Pall were all in attendance.
