Kaia and Presley Gerber are effortlessly cool.
The model siblings -- who count supermodel Cindy Crawford and Casamigos businessman Rande Gerber as their parents -- star in the new Calvin Klein Jeans campaign, looking impossibly gorgeous as always.
In the photos shot by photographer Willy Vanderperre, 16-year-old Kaia rocks an all-black denim on denim look, showing off her slim physique.
Meanwhile, 18-year-old Presley also sports an all-denim look, pulling off a cut-off black vest over a blue button-up and jeans.
This isn't the first time Kaia and Presley have slayed together. The two attended the CFDA/Vogue Fashion Fund Show in October, where they stole the show in chic looks.
