Like any self-respecting human, you’ve seen Christmas Vacation enough times to know exactly what to do when your boss gives you a jelly-of-the-month subscription instead of the pool-buying bonus you were expecting: You fly into a near-poetic rant, spewing some of the most creative insults ever heard this side of New Year’s Eve.
But what do you wear while you do it? This.
From the Christmas dinner-appropriate dress shoes to the bell-bedecked Santa hat, this is how you shop Clark Griswold’s look.

The Santa Hat: Clark Griswolds Santa Hat
You can find just about anything on Etsy, including a perfect replica of Clark’s bell-eriffic Santa hat. Of course, if you’ve got some DIY skills of your own, you can always just get a hat and sew on some bells.

The Cardigan: J Crew Rugged Merino Wool Cardigan Sweater
How do you pull off a casual-yet-classy vibe for the Yuletide? A cardigan. Clark’s had a shawl collar, marled yarn, and cuffed sleeves. It was a little oversized. And cool as hell.

The Oxford: Bonobos Stretch Oxford
Clean, classic, and comfortable, the traditional blue Oxford shirt is exactly what a family man and non-nutritive cereal varnish chemist wears when carving particularly dry turkeys.

The Tie: Clark Griswold Christmas Tie
No item captures that good-natured, Midwestern ‘80s charm like Clark’s geometric Christmas tie. Thanks to the movie’s enduring appeal, you can get an exact replica here and now. Or go for something with a little more heft inspired by the movie.

The Pants: Brooks Brothers BrooksFlex Wool Trousers
These are the no-nonsense, well-fitting slacks that inspire your boss to not press charges after your half-wit cousin kidnaps him.

The Belt: Lands’ End Comfort Fit Dress Belt
We may not know for sure where Sparky got his belt, but Lands’ End is a good guess. They’re synonymous with low-key comfort and started out in Chicago, just around the bend from the Griswold family home.

The Shoes: Clarks Malwood Plain Black Leather Shoes
While it’s likely any black dress shoe will serve, a pair from Clarks just seems exceedingly fitting.

Clark Griswold Stand-Up Cardboard Figure
And finally, nothing will ensure you have the hap-hap-happiest Christmas since Bing Crosby tap danced with Danny f-ing Kaye like a cardboard cutout of Clark Griswold himself.
