Get excited, Keeping Up With the Kardashians fans.

Khloe Kardashian, Kourtney Kardashian, Kylie Jenner, and Kendall Jenner went to Las Vegas together for the iHeartRadio music festival on September 21 and we must say, each sister is looking dazzling and chic for the red carpet.

Not to ignore Kourtney's "Like a Virgin" shirt and Kendall's super hot leggy look, but we're mostly focused on how adorable it is that Khloe and Kylie wore matching leather styles. While Khloe flaunted her midriff in a tight leather getup, her younger sis donned the trend with a baggy dress, strappy heels, and bright red lipstick.

So were these two biker chicks competing for the spotlight in such similar looks? No way!

Khloe lovingly posted, "My leather soul sister @KylieJenner."

Check out both of their fall styles and let us know which one you like best in the comments below.
