Christmas Vacation Style

If it's not a tradition in your house—watching National Lampoon's Christmas Vacation this time of year—it should be. Written by John Hughes and released in 1989, the twisted holiday classic kicks the typical yuletide schmaltz-fest in the teeth. It's full of zany antics, ageless slapstick and epic insults, of course. But at the heart of the film is an indictment of the genuine stress brought on each year by family obligations, unreal expectations and commercialism. Also nestled into the movie? Clark Griswold's wardrobe of masculine, all-American sportswear—from flannel shirts and puffer vests to hardy sweaters and hooded parkas.
