Khloé Kardashian stunned in Sin City.

The 29-year-old Keeping Up With the Kardashians star was all smiles as she made an appearance at Kardashian Khaos inside of the Mirage Hotel and Casino in Las Vegas Saturday, dazzling in a striped "Krop top" and high-waist skirt.

Khloé also showed off her updated hair color at the event, revealing even lighter ombre locks.

The public appearance marked one of Khloé's first since filing for divorce in December from hubby Lamar Odom, which she said on this season's premiere of Keeping Up With the Kardashians, caused her to avoid people.

"This whole thing is very uncomfortable," she told her sister Kourtney Kardashian. "I don't like being around people because I know what they're thinking."

"I've been in hiding because I'm afraid of people," Khloé continued. "I can't look at people in the eyes. And I'm not even the one who did anything."

Although she's admitted that the break-up has been "heartbreaking," The E! reality star has been keeping her head up following the split.

"I've been putting myself aside to save hopefully somebody else's life and now that I've come to terms that I can't, I have to move on with my life and that means changing a lot," Khloe said on the show.

She went on to tell Cosmopolitan that she was looking for a "a good fresh start" in 2014, adding, "I'm excited for this year to be over with…You only live once so let's make that one time perfect. We can't fix our mistakes and imperfections, so let's have fun. You get what you give out in life."

Don't forget to tune in to an all-new Keeping Up With the Kardashians Sunday at 9 p.m. only on E!.
