Gwyneth Paltrow hosted a party last night at the Chateau Marmont (the penthouse, of course), with the invite calling for cocktail attire. In true LA fashion, that translated to a mix of jeans, leather jackets, and the occasional silk dress. Chalk it up to the 5PM start time—or the reality of navigating Hollywood traffic straight from the day’s to-dos. Still, everyone looked great in that easy, unfussy way LA does best. Denim dressed up with heels, leather jackets (lots of leather, pretty much in this !), and just enough polish to make it feel special without trying too hard. I opted for a (naturally), a blouse, my usual jeans, this statement belt, and Chanel patent-leather pumps. Other day-to-night pieces that would have made the cut, all below: the Charvet x Chanel inspired silk tuxedo blouse, the pinstriped (love their new 11/10 , BTW), 's suede jacket (yum), and (yes, head-to-toe).
