Kaia Gerber faces crisp fall weather in bright blue sweater and black trousers during Malibu outing 

Temperatures may be dropping in Los Angeles.  

And Kaia Gerber faced the crisp Southern California fall weather with a blue sweater and black skinny jeans.

The 17-year-old carried her belongings in a Prada belt bag while chatting on her phone during an outing in Malibu on Monday.

Gerber, who appeared makeup free, wore her hair in a sleek bun. 

The Vogue cover girl paired her cozy sweater with a graphic tee and black Converse. 

She accessorized with gold hoop earrings.

The star shared an image later in the day while rocking the ensemble; she captioned it: ‘Show off.’

Kaia was named the new face of YSL Beauty just weeks ago. 

‘To be the new face of YSL is an opportunity to write a new story full of fun, color, and makeup,’ she said in a press release. ‘I love the DNA of a brand that is so subversive while being luxurious and cool!’

Gerber’s first campaign with the brand drops January 2019.

Aside from modeling, the Malibu native launched a clothing collaboration with Chanel’s Karl Lagerfeld in August.

‘I got to take inspiration from both our worlds [Paris and Los Angeles] and I think that they met in a really cool place,’ she told Jen Atkin during a Q&A on Instagram. ‘I wanted the collection to be super functional.’ 

The line features more than 50 unique pieces.
