Kim showed off her assets in a fitted calf-length frock that hugged her every curve.

She slicked back her long tresses in a sleek hairstyle and opted for no jeweled accessories around her neck.

Kim may have taken some style cues from little sister Kylie as she was seen the day before in an almost identical ensemble.
On Monday, the PacSun fashion collaborator stepped out with alleged beau Tyga in Calabasas just hours after Caitlyn Jenner's Vanity Fair cover had been released.
For the outing, Kylie was dressed in a strapless Soldier dress by Sorella Boutique. She accessorized the look with Tom Ford high heels and a black quilted Moschino backpack.
Apparently good fashion sense is a genetic trait among the Kardashian-Jenner family specifically in the case of Kim and Kylie, who share the same mother Kris Jenner.

In previous seasons of KUWTK, Kim has been vocal about how Kylie is the style guru in their extended family.
The 17-year age difference is not a factor for Kim as she has previously confessed to stealing clothes from Kylie's closet.
