Kim Kardashian West and her big sister Kourtney are in the business of doing good. The sisters teamed up to hand out food to those in need in L.A. while filming an episode of Keeping Up with the Kardashians on Wednesday, and they went casual for the occasion.

Kim wore a gray tank and light blue Yeezy Calabasas sweatpants that showed off her famous curves. She paired the comfy pieces with lace-up sneakers and layered gold necklaces and otherwise kept her accessories simple for the day of filming.

The sisters have been hard at work filming Keeping Up with the Kardashians around L.A. Earlier this week they filmed a Christmas special, going ice-skating in the 95-degree heat and even shopping for a spruce tree in October.

No word yet on when this charity-filled episode will air.
