An ugly Christmas sweater is a deliberately loud, tacky holiday knit, usually covered in reindeer, snowflakes, tinsel, bells or bad puns, that people wear for laughs at December parties. What started as a kitschy joke has become one of the most popular dress codes of the season, from office potlucks to family photos. This guide gives you DIY builds, funny and matching ideas, where to buy one, and a ready-to-use party and contest plan. For the rest of your holiday planning, start with our Christmas 2026 complete guide.
What Is an Ugly Christmas Sweater?
An ugly Christmas sweater is any holiday-themed sweater worn ironically because it is over the top. In other words, the more glitter, pom-poms and questionable reindeer anatomy, the better. However, the look has a longer history than most people think.
According to Mental Floss, people have worn festive knitwear since at least the Victorian era, and an 1896 Boston Globe ad already promoted Christmas sweaters for ladies, men and boys. Jingle-bell sweaters followed in the 1930s. Then, in the 1980s, restraint disappeared: entertainer Andy Williams embraced louder looks on TV, and in 1989 Chevy Chase’s Clark Griswold wore memorable holiday knits in National Lampoon’s Christmas Vacation.
The modern party trend, meanwhile, is usually credited to Chris Boyd and Jordan Birch, who threw a kitschy sweater party at a friend’s house in Coquitlam, a suburb of Vancouver, Canada. Most accounts date it to 2002. That party moved to a university pub, then a bar, and finally to Vancouver’s Commodore Ballroom, which hosted it through 2017. Notably, Mental Floss also reports an earlier sweater party in Missoula, Montana, in 2001, so the “first” title is still debated.
When Is National Ugly Christmas Sweater Day 2026?
National Ugly Christmas Sweater Day 2026 is Friday, December 18, 2026. The unofficial observance always lands on the third Friday of December, which makes it a perfect last workday before many offices slow down for Christmas on Friday, December 25.
It is not a federal holiday; instead, it is a fun awareness day listed by calendars such as National Today. Meanwhile, the UK runs its own charity version: Save the Children’s Christmas Jumper Day, which falls on Thursday, December 10, 2026, with a suggested donation of £2 for adults and £1 for children. Since its launch in 2012, it has raised more than £42 million, according to the charity.
| Year | National Ugly Christmas Sweater Day (US) | Christmas Day |

| 2027 | Friday, December 17 | Saturday, December 25 |
| 2028 | Friday, December 15 | Monday, December 25 |
Pro tip. If you plan to order sweaters or craft supplies online, buy them in late November. That way, you avoid the December crunch; see our Christmas shipping deadlines guide before you check out.
DIY Ugly Christmas Sweater Ideas (No Knitting Needed)
The best DIY ugly Christmas sweater ideas start with a cheap plain sweater and add 3D decorations with fabric glue, a hot-glue gun or safety pins. You do not need to knit, sew well or spend much; most builds below take one to two hours.
How do you make a DIY ugly Christmas sweater?
First, pick a base, then plan the design, and finally attach everything securely. Here is the simple five-step method.
- Choose the base. A plain red, green or white crewneck from a thrift store works best because you will not mind gluing on it.
- Sketch the layout. Lay the sweater flat and arrange pieces before you glue anything, so the design sits centered on your chest.
- Protect the back. Slide a piece of cardboard inside so glue does not bleed through to the back panel.
- Attach in layers. Start with flat felt shapes, then add tinsel, pom-poms and bells on top.
- Let it cure overnight. Fabric glue needs time; meanwhile, test any lights to make sure the battery pack is easy to reach.
| Supply | What it does | Where to get it |
|---|---|---|
| Plain sweater | The base layer | Thrift store, or plain crewneck sweaters on Amazon |
| Felt sheets | Cut-out trees, faces, letters | Craft felt sheets |
| Pom-poms and jingle bells | 3D noses, ornaments, texture | Pom-pom and bell craft packs |
| Battery LED fairy lights | The light-up effect | Battery fairy lights |
| Fabric glue or hot glue | Holds everything on | Fabric glue |
| Tinsel garland | Instant sparkle and trim | Dollar store or your own decoration box |
1. Tinsel Christmas Tree — Best for beginners
Glue green tinsel in a zigzag triangle on a red or white sweater, then add pom-pom “ornaments” and a felt star on top. It reads clearly from across the room, so it photographs well.
- Time: about 1 hour
- Budget: $ (under $25 if you thrift the sweater)
2. Light-Up Wreath — Best for winning “Most Lights”
Wrap a ring of garland on the front, weave battery fairy lights through it, and finish with a big felt bow. Tuck the battery pack in an inside pocket made from a felt square, so you can switch it on when the judges walk by.
- Time: 1.5 hours
- Budget: $ to $$
3. 3D Reindeer Face — Best crowd-pleaser
Use a brown sweater as the face, add googly eyes, a large red pom-pom nose and felt or pipe-cleaner antlers on the shoulders. Because it is so simple, kids can help make it.
- Time: 45 minutes
- Budget: $
4. Snow Globe Sweater — Most creative DIY
Sew or glue a clear plastic pouch onto the front, fill it with fake snow or confetti and a tiny figure, then seal the edges. When you jump, the snow moves, which is exactly the kind of detail judges remember.
- Time: 2 hours
- Watch for: seal it fully, since loose confetti will end up everywhere
5. Present Sweater — Easiest last-minute idea
Run wide ribbon vertically and horizontally across the sweater, then add a giant bow and a gift tag that says “Do not open until Dec 25.” It takes about 20 minutes, so it is the best option if the party is tonight.
- More quick DIY ideas: a fireplace with felt stockings, a gingerbread house with puffy-paint “icing,” a nativity made of plush toys, or an advent calendar with 24 felt flaps.
- No-glue option: use safety pins and iron-on patches, so you can strip the sweater and wear it normally in January.
Watch out. Only use battery-powered LED lights on clothing, never plug-in string lights. Also, keep small bells, buttons and pom-poms off sweaters for toddlers, because loose pieces are a choking hazard.
Funny Sweater Ideas That Actually Get Laughs
Funny ugly Christmas sweaters work best when the joke is readable in two seconds: a pun, a pop-culture nod or a visual gag. Meanwhile, keep office versions clean, because what is hilarious at a friend’s house can be awkward at work.
Funny ugly Christmas sweater ideas for any party
- Pun slogans: “Sleigh All Day,” “Resting Grinch Face,” “Yule Be Sorry” or “Elf Tired.” Iron-on letters make these easy.
- The Griswold tribute: a moose-and-reindeer knit with a felt “Cousin Eddie” name tag, a nod to Christmas Vacation.
- Tangled-lights disaster: wrap a strand of battery lights around yourself in a knotted mess and add a “Help” sign.
- Pet in a Santa hat: print your dog’s or cat’s face on iron-on transfer paper and add a felt Santa hat.
- “Naughty or nice” checklist: a felt clipboard with both boxes checked.
- Half-eaten cookie sweater: glue on a felt gingerbread man missing a leg, with crumbs made of puffy paint.
If you would rather buy a joke sweater than make one, browse funny ugly Christmas sweaters on Amazon and light-up ugly Christmas sweaters, then check sizing charts carefully since many run small.
Matching Family and Couples Christmas Sweaters
Matching family Christmas sweaters work best when each person wears one piece of a shared theme rather than identical copies. As a result, the family photo looks intentional and every outfit still stands alone.
| Theme | Who wears what | Best for |
|---|---|---|
| Santa’s crew | Santa, Mrs. Claus, elves, a reindeer for the dog | Families with kids |
| Milk and cookies | One milk glass, one cookie | Couples |
| Christmas lights strand | Each person is one colored bulb; stand in a row | Big families, office teams |
| Snowman build | Bottom, middle and head snowball | Groups of three |
| Naughty and Nice | One “Naughty,” one “Nice” | Couples, siblings |
| Same base, different art | Everyone gets the same color sweater and decorates their own | Party activity for all ages |
For ready-made sets, compare matching family Christmas sweaters and couples matching sweaters. Also, order adult and kids’ sizes from the same seller so the colors actually match. If you want something dressier for a second party, see our Christmas party outfit ideas.
Where Can You Buy One in 2026?
You can buy an ugly Christmas sweater at thrift stores, big-box retailers, online marketplaces such as Amazon and Etsy, or from custom-print shops. Thrift stores are cheapest and most authentic, whereas online stores have the widest range of sizes and themes.
| Where | Budget band | Pros | Cons |
|---|---|---|---|
| Thrift and secondhand stores | $ | Genuinely vintage, cheap, sustainable | Sizes are hit or miss; shop early in December |
| Amazon | $ to $$ | Huge range, fast shipping, family sets | Quality and sizing vary by seller |
| Big-box stores | $ to $$ | Try on in person, easy returns | Popular sizes sell out |
| Etsy and custom print shops | $$ to $$$ | Personalized names, pets, inside jokes | Longer production and shipping times |
| DIY | $ | Unique, wins “Most Creative” | Takes an evening |
On Amazon, the most useful searches are ugly Christmas sweaters for men, ugly Christmas sweaters for women and kids’ ugly Christmas sweaters. In addition, a joke sweater makes a reliable swap gift, so it doubles as a white elephant gift.
How Do You Host an Ugly Christmas Sweater Party?
To host an ugly Christmas sweater party, set the date (December 18, 2026 is ideal), make sweaters mandatory on the invite, plan simple themed food, and run a contest with clear categories and a prize. Everything else is optional.
Ugly Christmas sweater party ideas, step by step
- Send invites three weeks ahead. That gives guests time to thrift or DIY; also add a line such as “No sweater, no cookies.”
- Set up a DIY station. Put out felt, tinsel, bells, glue dots and spare thrift sweaters for anyone who shows up undecorated.
- Serve themed food. Sweater-decorated sugar cookies, a hot-cocoa bar, “reindeer” snack mix and a cookie-decorating contest all fit the theme.
- Build a photo wall. A tinsel curtain or a wall of wrapping paper is enough; then add a frame prop.
- Play games. Try sweater charades, “Pin the Nose on Rudolph,” a white elephant swap or holiday trivia.
- Queue the music. For example, start with a cheesy classics playlist from our Christmas party playlist.
- Crown the winners. Finally, hold the contest about an hour in, once everyone has arrived.
For decorations, reuse what you already own. However, if you need extras, search ugly sweater party decorations for banners, plates and photo props.
Contest Categories and Judging
The best ugly Christmas sweater contest uses four to six categories so more guests can win, plus a simple scoring sheet. As a result, the contest feels fair rather than a popularity vote.
Ugly Christmas sweater contest categories
| Category | What judges look for | Prize idea |
|---|---|---|
| Ugliest Overall | Maximum clash, clutter and commitment | A trophy or golden tinsel crown |
| Funniest | The biggest laugh in two seconds | Gag gift |
| Most Creative DIY | Original idea, homemade build | Craft store gift card |
| Most Lights or Bells | Sparkle, sound and spectacle | Fancy hot cocoa set |
| Best Matching Pair or Family | Shared theme, team effort | Board game |
| Most Festive Pet | Best-dressed dog or cat (optional) | Pet treats |
How do you judge an ugly sweater contest?
Score each entry from 1 to 5 on four criteria: ugliness, creativity, holiday spirit and presentation (how well the wearer “sells” it). Then add the scores, and break ties with a quick crowd cheer. Alternatively, for an office, use anonymous paper ballots so nobody feels pressured to vote for the boss.
Pro tip. Run a quick “runway walk” before voting. Because people judge what they see, a 10-second strut helps quieter guests show off details like hidden lights or a snow globe.
Our verdict
The best ugly Christmas sweater is the one you made yourself: a thrifted base, battery lights and a single clear idea beat an expensive store-bought sweater in almost every contest. So mark Friday, December 18, 2026 for National Ugly Christmas Sweater Day, send invites by late November, and pick contest categories in advance so everyone has a shot at a prize.

What should I wear to an ugly sweater party if I don’t have one?
Grab any plain sweater or sweatshirt and pin on tinsel, ribbon and a bow to turn it into a present, which takes about 20 minutes. You can also wear a festive cardigan with a Santa hat and battery lights, or pick up a used sweater from a thrift store the same day.
Are light-up ugly Christmas sweaters safe?
Light-up sweaters are generally fine when they use small battery-powered LED lights designed for clothing. Never attach plug-in string lights to a sweater, switch lights off when you are not wearing it, and keep the battery pack easy to reach. For toddlers, skip small bells and pom-poms that could come loose.
