Wednesday’s InStyle summer soiree drew a young crowd of film stars and fashion favorites to the Mondrian Hotel, where the fashion mandate appeared to be colorful prints and all-white ensembles. Early to pose for cameras was Ashley Madekwe, who sported a bright yellow Diane von Furstenberg jumpsuit with a Chanel belt. Nearby, indie actress Melonie Diaz donned head-to-toe Marc Jacobs. “I always go for comfort,” the “Fruitvale Station” star said. “This outfit is so Marc,” she added, pointing to her cropped sweater’s sequined stripes. Of her movie’s early awards buzz, she said, “It’s taken us all by surprise.” “Scandal” star Tony Goldwyn arrived in Giorgio Armani and John Varvatos to celebrate his Man of Style feature in the September issue. “They did a beautiful piece, I’m excited to see it,” he said. Jesse Metcalfe and girlfriend Cara Santana arrived hand-in-hand. As Julianne Hough arrived wearing a bright orange Halston Heritage maxiskirt, Santana exclaimed, “Look how good Julianne looks,” before running over to embrace her. Inside the party, newlyweds Shenae Grimes and model Josh Beech chatted poolside while sisters Aly and AJ Michalka manned the photo booth with Davida Williams. Elsewhere, Colin Egglesfield chatted with friends about training for his upcoming triathlon. “It’s my first one,” he said. “I’m not ready yet.” As the night wrapped, guests took home gift bags of Essie and Moroccanoil and self-serve candy bar bags.
