Pop up shops, ice cream pops, and pops of summer colors took over at producer Jennifer Klein’s 14th Annual Day of Indulgence party on Sunday, where guests including Christina Hendricks, Leslie Mann, Michelle Trachtenberg, and Hailee Steinfeld enjoyed a girls-only day of pampering, shopping, and sun. “It’s like a girls bonding day,” Hendricks told InStyle.com. “I like that it’s just women. And I like that you run into a lot of friends and just relax. And, of course, the shopping!” Yes, the shopping—guests left Klein’s Los Angeles home weighted down with bags of goodies, including clothes from Intermix, jewelry by Lizzie Scheck, a Clarisonic cleaning system, an Amazon Kindle, Givenchy mascara, Sperry Topsider shoes, Skullcandy aviators, and more.

Last weekend, a mix of British and American stars and socialites headed to Surrey, England to celebrate at Cartier’s International Polo Party. And we love seeing them in their summertime best! Both Cat Deeley (who is always fashion-forward on SYTYCD) and Leslie Mann opted to wear flowing, printed designs (Deeley’s was vintage, Mann’s Louis Vuitton) to the polo match, while Camilla Belle kept things crisp in white (with just a dash of color). Geri Halliwell broke the party’s casual fashion mold by sporting a skin-tight, figure-flattering Herve Leger minidress. The highlight of the event (besides the match)? The traditional afternoon tea, of course.
