Kim Kardashian was one of the many celebs to hit up billionaire Michael Rubin‘s Fourth of July White Party in the Hamptons. Alongside her supermodel sister Kendall Jenner and BFF La La, the “Kardashians” star arrived on-theme wearing a $1,860 sheer white crop top by Alaïa paired with a $2,730 matching high-waisted skirt.

But it was the littlest details that made the biggest impact. Around her snatched waist, Kim rocked a custom diamond necklace from Messika featuring a jaw-dropping 17-carat pear-shaped stone. The repurposed belly chain is estimated to cost around $1.3 million, reports Page Six Style.
