You are the holiday bonus, bb.

So, the difference between workwear and party clothes is crystal clear—so venturing into the gray area of an office Christmas party can feel a bit unnerving. Seriously, how do we combine office-appropriate attire (business casual—shudder) and party-ready ’fits (sparkles, fun fabric, statement pieces—the exact opposite, basically) in a way that actually looks good? Turns out, it’s not actually as scary as it seems. The key is to take aspects of both categories that you love—like luxe blazers and silky fabrics or A-line dresses and dance-floor-ready heels—and throw ’em together without thinking too hard about it.
Standard caveat: the holidays are stressful enough without having to worry whether or not Jan in sales will think your office Christmas party outfit is OTT or has an abundance of “unnecessary” tulle. Live your best life, bb. Wear what makes you feel as festive as possible! And only you know what's gonna fly at your workplace, but many of us are blessed (like us at Cosmo :)) with a more relaxed, inclusive dress code these days.

Don't wanna wear red? Np! You'll stand out in this magenta, feathered hem number.
Let's go, party people! It's time to bring out the sequins—you hear me? This mini one is callin' us by name.
Keep it simple and chic with a basic turtleneck and slip skirt.
You're gonna look SO adorbs in this ribbed, swing dress and you'll be the absolute cutest when you pair it with rosette-embellished shoes! Plus, you can wear this red stunner long after the holidays are over!
You'll def make a statement with these silver pants that you can also wear for all the New Year festivities, too! Tone down the vibes with a muted, slouchy cardigan top.
Turn loungewear into party-wear with a silky, elevated jumpsuit—one that feels like PJs but actually looks like you were making (holiday-related) boss moves all day.
I'm pretty sure everyone in the office will be asking you where you got this gorge metallic top from! Wear it with leather pants, heels, and a small clutch for extra chic factor.
Jewel tones have my heart and TBH, are always a win when it comes to the holidays. In other words, get this emerald bustier with pleated sleeves ASAP.
Wear all black and then throw on this sequin jacket for a lil razzle dazzle.
Oh hey showstopper! Go all out in this ruby red sequined dress with a mock neck, ruching, and assymetrical hem.
Sequins, but make it fashion—this sequin dress is super sleek for an office party that's a bit ~fancier~. This dress has it all: glitz, glamour, and a gorge silhouette sure to serve you well for years.
Whoever said peplum was dead clearly hasn't seen this strapless top. Pair it with a collared shirt and pants.
If you're going with a classic holiday color like red, but don't want to look like the literal decorations, just dress up your favorite sweater dress with a pair of sky-high heels or rocker-chic boots. It’s the perfect combination of workwear and party vibes.
If you're the chill type, a forest green corduroy shirt is your best bet. Go for your favorite jeans or wear with black leather pants to dress it up a little.
Winter white is always a vibe—and you can’t go wrong with a v-neck wrap sweater dress in this frosty hue.
Think outside of the box with this zebra jacquard minidress and some pumps.
This ensemble is perfect for when you’re trying to be just festive enough. Like, you could go all-out with reindeer antlers, or make it even more office-appropriate with a blazer and boots.
When in doubt, can you ever go wrong with a classic LBD and matching heels? Absolutely not.
Take your leather skirt up a notch and add a creamy sweater and party-ready booties.
