The inaugural InStyle Awards plus Olivier Rousteing’s 30th birthday party brought out the big names in Los Angeles. Predictably, the Kardashian-Jenner clan monopolized Rousteing’s bash, while Gwyneth Paltrow, Selena Gomez, Julia Roberts and more hit the InStyle red carpet. Meanwhile, in New York, some luxury brands hosted meals for various good causes — that would be Prada, which sponsored The Lunchbox Fund’s 10th anniversary dinner, and Chanel, which launched an initiative with TriBeCa Enterprises called “Through Her Lens: The TriBeca Chanel Women’s Filmmaker Program” with a luncheon at Locanda Verde. The amfAR Inspiration Gala rounded out the week, drawing Ryan Murphy’s celebrity fan girls from Paltrow to Lady Gaga. Here, the best party photos of the week.
