Kim Kardashian has celebrated her 39th birthday in true mogul style—with a brand partnership.

She stopped by one of her new KKW Beauty displays, at an Ulta in Calabasas, on Tuesday.

The reality TV star wore a showstopping outfit of a snakeskin crop top and a figure-hugging black skirt, as she helped shoppers choose beauty products.

Her long-sleeve top and an asymmetrical neckline and came just below her chest.

It seemed she was wearing a new pair of her solution wear, SKIMS, beneath her skirt, as it was semi-sheer.

Earlier in the day she shared herself in upcoming, double-bonded pieces from her brand. The skirt was cinched near her left knee and also had an asymmetrical hem.

Kim paired the look with black strapping heels, with the shorts point under the arch.
