Kylie Jenner -- Anything Khloe Kardashian Does ... I Can Do Better (PHOTOS)

Kylie Jenner is all about the family biz, which apparently now requires all the sisters to rep HARD for Adidas ... at all times.

Ever since big sis Khloe Kardashian's BF James Harden signed a $200 million dollar deal with Adidas -- Khloe AND Kylie have been sporting the gear constantly. It also can't hurt that the company cranks out Kanye West's Yeezys too.

Sooo ... Adidas: outfitting hoops superstars, NCAA teams, rappers and Kardashian asses everywhere.
