Don’t be fooled: The holiday party season isn’t over yet. Whether you’re entertaining at home, hitting the town with friends, or attending a cocktail party, I have some suggestions to make sure you—both guys and gals—look your best.

Women

A clutch is an evening essential. Instead of playing it safe with black, pick up a novel silver metallic minaudière (pictured, above)—a hard-case clutch—that pairs as well with jeans and a T-shirt as it does with a sophisticated black cocktail frock. $95, Rustic Thread, 3716 W. 32nd Ave., 303-351-3535, rusticthread.com

This festive silver metallic leather pencil skirt by Milly is a great option for nearly any occasion. Wear it for a home dinner party with an oversize turtleneck sweater paired with menswear-inspired flats, or dress it up with a dove gray or cream cashmere crewneck and black pointed-toe pumps. $525, Goldyn, 2040 W. 30th Ave., 720-489-0580, shopgoldyn.com

Go a little edgy for a night out with friends with a sexy yet chic strapless jumpsuit in a bold print (this one by Tart Collections is also available in solid black if you’re not feeling quite so daring). Pair it with a bomber or tux jacket, a sleek clutch, and pointed-toe pumps to keep the look elevated. $176, Dragonfly, 3615 W. 32nd Ave., 303-433-6331, facebook.com/dragonflyapparel

This double-breasted blazer in liquid black by Aldasair is a sexy choice for cocktail hour. It pairs well with black denim for a casual look; wear it with the matching pant for a modern twist on a tuxedo suit. $862, Moxie, 5936 S. Holly St., Greenwood Village, 303-694-0773, moxieinstyle.com

These 24-karat gold plated bangles by Anna Bee are perfect for stacking. They’re a timeless accessory to accent any look. $94 to $98, Willow, 2595 Canyon Blvd., Boulder, 303-818-5950, willowboulder.com

Wearing a pair of menswear-inspired flats for an evening out puts a fresh spin on this enduring trend. Wear these Donald J. Pliner patent leather and haircalf oxfords with an A-line or pencil skirt for a mod look or with an LBD for a girlish twist. $268, The Garment District, 2595 S. Colorado Blvd., 303-757-3371, garmentdistrictcolorado.com

Men

Sure, you can wear jeans for a casual evening at home, but if you’re the host, it’s nice to put in a bit more effort. My suggestion: Up the ante with colored wool trousers by American heritage brand Hertling (a 90-year-old manufacturer). Top them off with a mélange crewneck sweater or shawl collar knit, and you’ll be the best dressed host in town. $290, Sully & Co., 2443 Eliot St., 720-398-8064, sullyandco.com

A knitted (instead of woven) blazer with a subtle print—I’m digging paisley—adds edge to a wardrobe staple. Pair your jacket with black jeans or skinny wool trousers for a night out. $269, Scotch & Soda, Cherry Creek Shopping Center, 3000 E. First Ave., 303-223-0864, scotch-soda.com

This season, the solid turtleneck sweater for men—a look championed by 1970s designer Halston—saw a major comeback. Banana Republic’s T-neck sweater looks great on its own or as a layering piece worn under a jacket (it’s pictured paired with a peacoat). $130, bananarepublic.com

For a formal affair, you could go traditional and wear all black. Snooze. Change it up with brown velvet for evening—like this sharp shawl-collar dinner jacket by Suitsupply. It gives a nod to the men’s European runway (check out the Fall 2014 show by Gieves & Hawkes) while pairing it with the usual tux elements—white shirt, black bow tie, and black trousers—keeps it familiar. $399, Suitsupply, 299 Detroit St., 303-876-9900, suitsupply.com

The Chelsea boot is a forever classic for men. This version by To Boot New York will look great with slim denim and a jacket or a crewneck knit for a relaxed night with friends. If you’re a suit kind of guy, wear them with a trim-fit two-piece during the workweek. $398, Scarpaletto, 1436 Larimer St., 303-321-5771, scarpaletto.com

A good-looking accessory is key to finishing off any evening look. If you’re wearing a jacket, make that accent a pocket square. This printed silk version by Dion Neckwear comes in a variety of colors and prints. $65, Moda Man, 1459 Larimer St., 303-862-5949, modaman.com
