Kendall Jenner celebrated her 21st birthday this week and of course younger sister Kylie was there to help her celebrate.
The Kardashian clan and friends headed to Delilah in Los Angeles to party with Ken and Kylie certainly made an entrance.
The 19 year old wore rather racy attire, showing off her assets in a see-through mesh top and form-fitting leather trousers.
The trousers featured lace up front and side panels that exposed further skin and added a pair of sparkly heeled sandals to lengthen her pins. She was oozing serious sex appeal.
The leather trousers are by Unravel, a brand worn before by the likes of her sister Kim, Gigi Hadid and Alessandra Ambrosio, so Kylie is in good company!

Alongside the Jenner sisters, the Kardashian girls were also out in force - apart from, of course, Kim, who has retreated from the spotlight after she was robbed at gunpoint in Paris earlier this month.
Kourtney and Khloe stunned in figure-flashing black while they were joined by momager Kris Jenner.
Other stars to attend the bash included Kendall's father, Caitlyn Jenner, her model pal Hailey Baldwin, and family friend Cindy Crawford and her kids Kaia and Presley.
