And it was no different today as Kim showed up both Kourteney and Khloe, flaunting her perfect curves in a plum body con dress.
The 30-year-old reality star and her sisters were promoting their new clothing line 'Kardashian Kollection' at Sears department store in Cerritos, California, today.
Kourteney opted for black trousers with leather trim and ankle zipper detail, a white T-shirt with fringe detailing and a black tuxedo jacket.
Khloe meanwhile was relaxed jeans, a black sheer top and a fur caplet.
All three girls did however wear super high heels; Khloe in over-the-knee Christian Louboutins, Kourteney in a pair of the designer's platform pumps and Kim in T-bone Mary Janes.
