InStyle's editorial guidelines Updated on May 5, 2017 @ 03:30PM Pin Share Tweet Email Photo: Billy Farrell/BFA How to make sure everyone turns heads when you walk in? Ask Kate Bosworth. The actress dressed to the nines Thursday night in Los Angeles in a look that easily would have landed her a Best-Dressed spot during awards season. Yes, guests inside Roger Vivier’s Strass: Day to Night with Bruno Frisoni party were major (looking at you, Demi Moore), but it was Bosworth who wowed thanks to a ruffled, off-the-shoulder Ellery top that she paired with perfectly tailored black trousers. Obsessed. Earlier this week, ladies who lunch like Sophie Turner came out to support and empower organizations like Women for Women International, which hosted a chic and inspiring luncheon. Similarly in New York, Helena Christensen, Julianne Moore, and Scarlett Johansson looked unbelievably fabulous at Planned Parenthood’s 100th anniversary gala. Of course, this week’s buzziest ticket was the Met Gala. After the ball, celebrities parted ways and headed to hours-long after parties inside the Standard’s Boom Boom Room and 1OAK.
