Kim Kardashian Wore a Really Sparkly, Sheer Skirt — and Just a Bra as a Top

The Balmain army was out in full force on Thursday night to celebrate the opening of its Flagship Los Angeles boutique, as well as the release of a collaboration with Beats By Dre.

For the party, held at the new Melrose Place outpost, a number of A-listers joined the French brand’s creative director Olivier Rousteing in his designs, including Kerry Washington, Hailee Steinfeld, Kim Kardashian West, and more.

However, there was one Balmain loyalist that was noticeably missing. Kylie Jenner, who serves as the face of the campaign for the special edition headphones, skipped. According to Snapchat, she was driving around Calabasas at the time of the event. While the reality star’s makeup was done, selfies show her wearing a white zip-up hoodie, which definitely didn’t mesh with the Balmain dress code: tight, leather, fringe, sheer.
