Beside her on the white sofa, Kylie wears a tight black skirt and long-sleeved crop top, with strappy black heels.

The Keeping Up With The Kardashian stars are expanding their family's business empire with the new fashion line, which debuted last month.

Kylie also has her Lip Kit By Kylie business, selling a range of natural and pink colored lipsticks. 

And the 18-year-old also shared a photo of herself lounging on a giant lip sofa on Wednesday. 

The reality star wears black leggings and matching jacket, sunglasses and grey sneakers as she lounges on the bright red lips.

The youngest of the Kardashian-Jenner sisters also launched their own video game last week.

The game, a spin-off of Sister Kim Kardashian's hit Hollywood game, quickly hit the top of Apple's app charts. 

The game, called Kendall & Kylie, takes fans on an interactive adventure through Hollywood and lets users customize their characters and interact with the Jenner sisters and their friends.
