Make a mark in mirrored shades

It's easy to be envious of Kendall Jenner. Reason 589, she has a killer body, she's a model, she's got an awesome sense of style, and she is wearing a pair of shades that are to die for!

Just look at those statement sunglasses. Kendall added a glam touch to her revealing outfit. She paired her Victoria Beckham sunglasses with a mauve jumpsuit, a green and white striped Celine bag along with white sandals.

Kylie, 17, was equally stylish in a slim-fitting strappy dress and gladiator sandals.  

The pair were spotted at Joan's On Third restaurant in West Hollywood, a day after their father Caitlyn Jenner was honored at the ESPY Awards.

En route to the eatery, Kylie shared numerous videos on her Snapchat account showing her big sister behind the wheel singing along to a French Montana featured single.

Earlier this month, Kendall sparked both outrage and confusion with a short video of her appearing to drive erratically.

Kylie posted a clip on Snapchat showing her sibling apparently driving with both of her hands off the wheel and her left leg sticking out of the window.

While it is unclear if the video image had been flipped, with Kendall actually in the passenger seat, the footage nonetheless caught the attention and criticism of fans online.

The bizarre and confusing video sees Kendall yelling: 'I fixed it! I f**king fixed it!'

What she is referring to is unclear as well as how she might be driving in such a compromised position, if she is driving at all.

Nonetheless, the clip raised more than a few eyebrows, with many comments citing the apparently poor driving technique.

Shortly after the incident, Kendall took to her Twitter page to make a statement about the Snapchat video.

'No hands and a leg out the window?! I know you guys think I am EXTREMELY talented but I'm not THAT talented people,' she wrote.

On Wednesday, they attended the ESPY Awards to show support for their transgender parent Caitlyn, who accepted the prestigious Arthur Ashe Courage Award.

The sports bash was the first appearance for the 65-year-old former Olympian since confirming her gender transition from Bruce to Caitlyn in April during the 20/20 interview with Diane Sawyer.

Also at the ceremony was Kendall and Kylie's older siblings both from the Jenner and Kardashian families.

Burt, Brandon, Brody and Cassandra wore black to match with Kourtney, Kim and Khloe at the event. The brood - all in their 30s -  skipped the red carpet and came out during the commercial break minutes before Caitlyn's segment.
