The two reality stars were spotted heading out for a lunch date together on Thursday (19 September) and as usual, they were dressed to kill with their hair and make-up styled to perfection too.
Khloe, 29, demonstrated her fashion credentials in a pair of figure flattering tailored trousers, some stillettos and a cute white and black bomber jacket.
She also wore her long hair up in a dramatic sleek ponytail and completed her look with a popping red lip, a pair of sunglasses and some gold jewellery.
Meanwhile, older sister Kourtney showcased her quirky style in a white and blue skort, a navy blue blouse and a matching coloured turban.
She finished off her ensemble with some nude heels and an eye-catching gold belt, while carrying an unusually large white handbag.
The sisters appear to have just visited their LA based clothing store, since Khloe was snapped holding a bag of goodies emblazoned with the well-known DASH logo.
Earlier this week, both ladies made a whirlwind trip to Las Vegas to promote their new Kardashian Kollection clothing line and they clearly haven't grown tired of one another, as they dined out at Ago restaurant yesterday.
No doubt Khloe is keen to have her eldest sibling around at the moment, while she struggles with reports that her marriage to Lamar Odom is on the rocks.
The curvaceous star was most recently hit by rumours that she and her husband are now leading separate lives after he was alleged to have been hiding a drug problem from her. Reps for Lamar have not commented on the allegations yet.
But despite all the speculation that her relationship is going through a tough patch, Khloe is putting on a brave face.
Yesterday, she attempted to divert attention away from her marriage by posting a snap of herself with pop superstar Katy Perry, taken at Katy's recent summer barbecue.
Katy can be seen in the picture wearing a cute sunflower print ensemble and Khloe is rocking her favourite denim shorts and checked shirt combo.
