The two youngest sisters of the Kardashian-Jenner clan are having an amazing week, as not only Kylie and Kendall Jenner's clothes line is getting launched, but the two beautiful ladies also just celebrated their high school graduations together, as Kylie just finished school and Kendall did last year.

Of course, as one of the biggest models right now, Kendall Jenner's clothes knowledge is a bit more interesting than most people's, so she's joining Kardashian family business along with little sister Kylie to release their new clothing brand together, Kendall and Kylie.

According to The Mirror, Kylie and Kendall Jenner's clothes website is now available online, and they're showing off the first item of their collection: cropped tops designed by the two youngest daughters of Kris and Caitlyn Jenner!

Their new clothing items are available on kendall-kylie.com with tees going for $42, with the promise that they’ll make users look not madly unlike how Kylie and Kendall Jenner’s clothes look like on them, though of course they’re gorgeous reality stars and models.

Zap2It reports that the cropped tee is specifically from Kendall Jenner’s clothes, called the “Klub” belly shirt from the sub collection “Kendall’s Closet,” though there’s another one for team Kylie, from “Kylie’s Closet.”

However, it’s not all business for Kendall and Kylie, as, following the 17 year-old’s high school graduation last week, the two close sisters decided to party hard to celebrate not only Kylie but also Kendall having left school last year.

According to Entertainment Tonight Online, the reality stars’ party was as big as could be expected from the Kardashians, as the youngest sister of the clan got a Rolex while all her family celebrated along with them – including how big sister Khloe Kardashian started twerking on Snapchat!

Congratulations for Kylie and Kendall Jenner’s clothes line and their graduation!
