In a StyleList exclusive, J.Crew gives us a sneak peek at images of Katie Holmes, Josh Duhamel, and their costars in the upcoming film "The Romantics," all decked out in J.Crew party attire.

The photos will appear in J. Crew's upcoming September catalog. The looks, drawn from the limited-edition Collection line for Fall 2010, are part of J.Crew's wardrobe contribution to the movie.

For the photos, Holmes and Duhamel dance around with Malin Åkerman, Adam Brody, Jeremy Strong, and Rebecca Lawrence.

In the film, the actors play a group of college friends who reunite at a wedding on Long Island, NY, where a romantic triangle ignites. (The missing pieces are "True Blood"'s Anna Paquin, who plays the bride, and Elijah Wood.)

As if the cast couldn't get any sweeter, the photos show them goofing around with cupcakes, feeding each other with the requisite dab of frosting on their faces.

The women gleam in a variety of shimmering styles. Åkerman wears a dark bronze sequined miniskirt; Lawrence swings her hips in a short, sunset-colored brocade sheath.

Holmes, meanwhile, wears a pale peach dress dripping with beaded fringe -- a look that practically begs to go dancing after the rehearsal dinner. (Something tells us that the film's bridesmaids dresses won't be the standard-issue taffeta horrors.)

In typical J.Crew fashion, the dressy duds are juxtaposed by boyish pieces. Åkerman layers on a sweatshirt vest, Lawrence tops her dress with a denim jacket, and Holmes toughens her wispy dress with a dark belt.

J.Crew polled the models-for-a-day about their romantic preferences and shared the surprising answers with StyleList.

Åkerman cracked that her most romantic word is "doofpot." Brody planted his tongue firmly in cheek, naming "The Shining" as the movie he finds most romantic and the score to "Gremlins" as his swoon-worthy song.

Unsurprisingly, Mrs. Tom Cruise named Paris' Eiffel Tower (where she got engaged) as her most romantic place.

She also divulged that "Songbird," by Fleetwood Mac, is her favorite lovestruck song and her favorite romantic words are "good morning."

As for Duhamel? J.Crew tells us, "Josh was off being romantic and couldn't answer our Q&A."

"The Romantics," which premiered at the Sundance Film Festival, will open in limited release on September 10.
