Kylie Jenner turned heads and raised eyebrows when she was spotted wearing a racy and super sexy sheer catsuit for the party that was thrown by her older sister Khloe Kardashian over the weekend.

The 17-year-old reality star from the E! Show "Keeping Up With The Kardashians" attended Kardashian's birthday party that was celebrated on Sunday. Jenner showed off her bod in a black outfit and topped it off with a braided hair that was colored black and gray, different from her usual blue hair.

Meanwhile, Kourtney Kardashian celebrated her 36th birthday at the 10AK club located in Mirage Hotel & Casino in Las Vegas. Kourtney was joined by her long-time partner Scott Dissick and her younger sisters Kylie and Kendall Jenner, Daily Mail reported. 

After the Las Vegas party, Kourtney also had a birthday celebration at their mansion on Sunday. The party was a pool-side celebration so Kourtney and the two Jenner sisters showed off their bods as they snapped photos of them wearing bikinis.

Kourtney wore a black bikini topped with a denim shirt while Kendall wore a maroon bikini under a khaki two-piece suit.

For Kylie, she wore a cream two piece bikini and covered her lower part with a tracksuit pants. However, she did show off a part of her derriere in a snap she posted on her social networking site. She also wore a baseball cap to complete her look. Hours before posting the photo, she photographed herself wearing a long coat and boots as she bid farewell to Coachella.
