Christmas Party Outfit Ideas: 12 Looks, Sorted by Party

A good Christmas party outfit depends less on the date than on the room: a friend's living room, a bar full of ugly sweaters and a candlelit cocktail party all land in the same three weeks and want different clothes. The twelve holiday party outfits below are sorted by the kind of party on the invite, and most of them are built from what's already in your closet plus one festive piece. Going to the office party instead? That one has its own rules, covered in what to wear to a work Christmas party.

Christmas Party Outfits for a Friend's House

Somewhere between the dinner table and the sofa, and the shoes might come off at the door.

1. Velvet trousers and a fine knit

Wide-leg velvet trousers in black, bottle green or burgundy, a fine ribbed knit tucked in, small gold hoops. Velvet does the festive work by itself, so the top can be the plainest thing you own. It also passes the house-party test: if the host asks for shoes off at the door, the outfit still looks finished in socks (pick a pair in a color that goes, and without holes).

2. Sequin skirt, chunky sweater

A sequin or metallic pleated midi skirt, an oversized cream crewneck, sheer black tights and flat ankle boots. The sweater turns the sparkle down to living-room level, and the skirt stops a cozy sweater from looking like you came straight off the couch. Two pieces, no overthinking, and it holds up from a 6 p.m. potluck to the last round of cards after midnight.

Ugly Sweater Party Outfits That Still Look Put Together

3. The ugly sweater, with everything else quiet

The sweater is the costume, so everything around it stays plain: dark straight jeans or black trousers, clean boots or sneakers, no extra festive jewelry. Wear a thin cotton tee underneath. Acrylic Christmas sweaters get hot fast in a crowded apartment, and you'll want the option of taking it off without ending up in a thermal. If there's a prize, it usually goes to commitment (battery lights, pom-poms, a partner in the matching one), not to adding more red and green elsewhere.

4. The Fair Isle loophole

Don't want to buy a sweater you'll wear once? A real Fair Isle or Nordic-pattern wool knit usually passes at an ugly sweater party, and it goes straight back into rotation in January with jeans. Pair it with cords or dark denim and lace-up boots. It works the same for men and women, and it's the easiest couple's option: two different patterns in the same two colors look coordinated without being matching sweaters.

Dressy Cocktail Christmas Party Outfits

5. Red satin slip dress and a black blazer

A red satin midi slip dress, a black blazer on or over the shoulders, sheer black tights and a pointed pump or slingback. Red is the obvious Christmas color, and satin keeps it grown-up instead of Santa. The blazer has two jobs: warmth between the car and the door, and a way to make the same dress work at a restaurant table instead of a dance floor.

6. The black velvet dress

A black velvet dress anywhere from knee to midi length, one piece of gold jewelry and a heel you can stand in for three hours. Velvet catches low light in a way flat black crepe doesn't, and most cocktail parties are lit low. Swap the gold for a red lip if you'd rather keep your ears bare. More ways to make all-black look like a choice are in our black outfit ideas.

7. Sequin top, tuxedo trousers

For anyone who'd rather not wear a dress: a sequin or lamé top, black tailored trousers (a satin side stripe is a bonus), pointed heels or a sleek loafer, hair up. The sparkle sits at eye level where the conversation happens, and trousers mean you can sit, dance and take stairs without thinking about a hem. The top carries straight into your New Year's Eve outfit a week later, so it earns its price twice.

8. Velvet jacket and roll-neck (men)

A velvet blazer in navy, bottle green or burgundy, a black or charcoal merino roll-neck, dark wool trousers and black leather shoes or Chelsea boots. It looks festive without a novelty tie, and the roll-neck settles the tie-or-no-tie question before it starts. When an invitation says "festive attire," this is one of the cleanest ways to answer it.

Casual Christmas Party Outfits (Yes, Jeans Work)

9. Dark jeans and a sparkly sweater

Dark indigo or black straight jeans, a lurex or metallic-thread sweater, heeled ankle boots, one bold earring. Jeans are fine at a casual Christmas party when they're dark, clean and fitted, and the top does the dressing up. Faded, ripped or light-wash denim is what makes it look like you forgot there was a party. For drinks at a bar or a neighbor's open house, this is the outfit to reach for first.

10. Sweater dress and knee boots

A ribbed knit midi dress in camel, cream, gray or deep red, knee-high boots in leather or suede, a belt if you want a waist. It's as comfortable as loungewear and looks like a decision. Add a fine gold chain or a velvet hair bow and it becomes a Christmas outfit rather than a Tuesday one. There are more knit-and-boot pairings in our winter outfit ideas.

Family Christmas Party Outfits for a Long Day

Four hours at the table, a floor full of kids, and every camera in the house pointed your way.

11. Tartan skirt and a cashmere crewneck

A tartan or plaid midi skirt, a crewneck in cream, navy or forest green, opaque tights and loafers. Tartan looks right in every photo, from the one on the grandparents' mantelpiece to the group shot in the hallway, and a wool skirt with a wrap or elastic-back waist is the kindest thing you can wear to a three-course lunch. If the family is planning a group picture, our guide to family photo outfits covers coordinating without matching.

12. Cords, a button-down and a cardigan (men and women)

Corduroy trousers in brown, olive or navy, an oxford shirt, a shawl-collar cardigan over it, suede boots or clean leather sneakers. Everything survives sitting on the floor for a board game with the kids, and the cardigan comes off once the oven has been on for six hours. It's the same outfit that works on Christmas Day itself, and there are more of those in our Christmas outfit ideas.

How to Pick a Holiday Party Outfit From the Invite

Invitations rarely spell out a dress code, but the wording usually gives it away:

• "Casual," "come as you are," or a message in the group chat: outfits 9, 10 or 1.
• "Festive attire": one festive fabric (velvet, sequins, satin) plus a real shoe, so outfits 1, 2, 7 or 8.
• "Cocktail," or a venue with tablecloths: outfits 5 to 8.
• "Black tie": step past this list to a floor-length dress or a formal midi with sleeves, or a tuxedo, and keep the festive part to a velvet fabric or a red lip.
• Anything that mentions sweaters: outfit 3 or 4, and don't be the only one who skipped it.
• Lunch at a relative's house with kids around: outfit 11 or 12.

What to skip is short. Red and green head to toe looks like a costume unless it's an ugly sweater party, and a heel you can't stand in ruins a party where nobody sits down. Pick the one festive piece, keep the rest simple, and the outfit looks deliberate. If you're torn between two of these, Klodsy can show both on your own photo before you decide which one to iron.

Shortcut: when you can't tell how dressy it is, pick the outfit one level up and bring a flat shoe in your bag.

The same read-the-room logic works for birthdays and every other invitation in our party outfit guide. And if the closet is looking thin this December, try Klodsy to build Christmas party outfits from the clothes you already own.
