For J. Crew's September catalog, the red-hot label booked some seriously chic models —The Romantics entire cast! Katie Holmes, Josh Duhamel, Adam Brody, Malin Akerman, Rebecca Lawrence and Jeremy Strong are convincing as their role as tight-knit college friends, goofing off on set in glittering dresses piled high with J. Crew's signature layers and stunning jewelry and neat, preppy suits from the label's weddings and parties collection. Holmes (left) models a crystal briolette dress ($1,500) and an olive poplin workshirt ($72). Although the issue doesn't hit J. Crew stores until September 10th—we're already lusting after every single look. Check out the sneak peek and preview J. Crew's September catalog cover in the gallery below, then watch the cast behind the scenes after the jump!
