Let the winter holiday party bum rush begin!

Every night’s been an endless stream of hobnobbing with the young and the restless, and you’re not the only thing that’s tired. Psst: Somebody’s due for a fashion refresher.

For those who have mastered the art of dressing up by dressing down, look no further than Klasse LA, the west side’s new one-stop select shop. Serving up an international metropolitan fashion platter, Klasse brings together Japan’s Hysteric Glamour, England’s Umbro by Kim Jones, France’s A.P.C., Sweden’s Dunderdon, and American’s favorite German export, Adidas Fashion. Fancy the perfect accoutrement? Sexy shoes, wallets, bags, belts, and jewelry have all been lovingly assembled to top off your ensemble.

And seeing as the owner’s last effort was beloved Indigo Flower, expect nothing less than the best the design market has to offer. Whether you’re destined for a Dogtown beach bash or headed for another party in the hills, stop by and scoop up casuals that are both high style and high quality.

They, like you, are in a class of their own.

Klasse LA, 2409 Main Street, between Hollister Avenue and Norman Place, Santa Monica (310-581-0520).
