However, Kim and Khloe Kardashian made sure they were well prepared for the change in climate as they headed to Chicago today.
Jet-setter: Kim Kardashian was spotted at LAX airport today as she prepared to fly to Chicago
Khloe, 27, wore a fairly plain and slightly sheer white long sleeve top with black skinny jeans and moccasin sandals.
ID at the ready: Kim was seen holding her driving license as she made her way through LAX
She wrote: ‘Just finished packing 4our Chi/NY trips. So sleepy.
ForeverMalika kept me company &of course @RealLamarOdom entertained us with his raps ;)’
All wrapped up: Khloe was also wearing a considerable amount of clothing for the plane ride
Mother and manager: The star was with Kardashian matriarch Kris Jenner
Although her manager mother was following closely behind, wrapped up in navy military jacket, the star looked rather glum as she embarked on the journey to promote their Kardashian Kollection clothing brand at Sears without her eldest sibling.
An absent Kourtney – who is carrying her second child with boyfriend Scott Disick – has only just arrived back in town after enjoying a birthday getaway with her beau and son Mason.
She doesn't look impressed: Kim barely cracked a smile for a fan as she arrived in Chicago
The 33-year-old wrote about eating from a West Coast fast food chain for the first time.
She posted: 'Just had IN N OUT for the first time! Can u believe it?! I asked @ScottDisick to get it for me tonight for a relaxing birthday din din. Yum.'
As her relatives arrived in Chicago, Kim snapped a picture of her luggage as it was taken off the American Airlines aircraft.
She captioned the image: 'My bag made it ;-)! Chicago here we come!'
Friendly: Kris was a little more welcoming of fans at the airport
