Super Saturday is best described as a couture garage sale, but with celebrity guests and a tony Hamptons setting. InStyle has hosted the event with Donna Karan and Kelly Ripa for several years; this time, Twilight star Ashley Greene is set to join in. The 13th annual sale will stocked with merchandise from over 200 designers, including Diane von Furstenberg, Catherine Malandrino, Elizabeth & James and Giorgio Armani, and it’s all for a good cause: Proceeds benefit the Ovarian Cancer Research Fund. If you can’t make it to the Hamptons this weekend, QVC will be broadcasting the event from 2:00 to 4:00 p.m. EST, offering viewers the chance to purchase a variety of items from the sale including apparel, accessories and beauty. Sounds super.
