With all four Fashion Weeks over (never forget!), there's suddenly room in our schedules to enjoy normal non-fashion activities like, say, go to the movies.

Numero Uno on our must-see list? "Couples Retreat," which opens today and stars the "money" combo of Vince Vaughn and Jon Favreau, as well as leading ladies Kristin Davis and Kristen Bell.

The film centers around several couples who find themselves on a not-so-idyllic tropical vacation; you can imagine the hilarity that follows...

StyleList had a chance to talk to the cast (watch the above video), so naturally the conversation turned to -- what else? -- fashion and beauty.

On the subject of her recently shuttered clothing line -- prompting Favreau to quip, "There goes my Christmas list!" -- Kristin Davis had this to say:

"It was a great thing to be able to try a whole other job that's not my job, but we launched in August '08, beginning of Recessionville -- pretty hard."

Kristen Bell, meanwhile, weighed in on her desert island beauty must: "If you're going to a desert island without SPF, you might as well bring a rope and hang yourself," she told us.

Rosebud Salve and the Elizabeth Arden Eight Hour Stick also got Bell's seal of approval, much to co-star Jason Bateman's amusement. Plus, the "couple" reveals a sordid Halloween costume past.
