They may be sisters but Kylie Jenner and Khloé Kardashian certainly have different tastes when it comes to denim.

Jenner recently took to Instagram to share a sexy snap of herself in a new pair of jeans. While posing on the edge of the bed, the 19-year-old lip-kit queen gave a special shout out to the label Fashion Nova. The jaw-dropping image received more than 2 million likes since it was posted and shared with her 82 million followers.

"Obsessed with my new @fashionnova jeans. Get them at #ad," Kylie Jenner captioned her Instagram photo. Instagram

The promotion may seem strange considering her sister just got in the jean game. Kardashian, along with business partner Emma Grede, co-founded the denim brand Good American earlier this year. The Good American collection was designed with “corset slimming elasticity," and has been marketed as a brand that flatters all figures.

Khloé Kardashian
Khloé Kardashian's denim band Good American reportedly reached $1 million in sales on its first day. Instagram

While both jeans seem to hug the famous sisters' curves just right, Jenner's choice is far more reasonably priced. Jenner's Fashion Nova "Classic High Waist Skinny Jeans" cost only $34.99 while the 32 year old's Good American "Good Waist" jeans retail for $169.

Despite the fashion face-off, it looks as though there is no bad blood between the famous siblings. Jenner and Kardashian celebrated Christmas Eve together, along with their other sisters, at mom Kris Jenner's over-the-top holiday party.
