20+ Casual Casual Holiday Outfits Christmas — Relaxed Looks 2026

Let’s be honest about something: some of the very best Christmas moments happen in your softest clothes. The bleary-eyed present opening, the marathon movie afternoons, the slow brunch in slippers — these moments deserve outfits too, just wonderfully comfortable ones.

Relaxed never has to mean sloppy, though. The trick is choosing soft fabrics with real intention — quality knits, thoughtful layers, and cozy textures that look every bit as good as they feel against your skin on a cold December day.

Here are twenty relaxed Christmas looks that prove comfort and style were never opposites in the first place. Pull on something soft, pour something warm, settle into your favorite corner — and enjoy every single cozy minute of the season.

1. Slouchy Grey Sweater and Lightly Ripped Jeans

The slouchy grey sweater is the sweatpants of knitwear — universally flattering, endlessly comfortable, and somehow always chic. Pair it with lightly ripped jeans (emphasis on lightly) for a look that’s relaxed without tipping into messy.

• Sweater: Heather grey, slightly oversized, with a wide neckline that slips off one shoulder.
• Jeans: Relaxed or straight fit with minimal distressing at the knee.
• Shoes: White sneakers or fuzzy-lined slip-ons, depending on your plans.

Add a delicate necklace and a topknot, and you’re ready for everything from gift-wrapping to a casual coffee date. This is the outfit equivalent of a deep breath.

2. Oversized Flannel Shirt Over a White Tank and Leggings

There’s a reason the oversized flannel never goes away: it’s basically a socially acceptable blanket. Worn open over a white tank with black leggings, it’s the ultimate Christmas-morning-to-afternoon outfit.

Choose a flannel in a classic red-black buffalo check for maximum holiday vibes, or a softer muted plaid if you prefer subtlety. The tank underneath should be long enough to cover the leggings’ waistband. Scrunch the flannel sleeves to the elbow for that lived-in look.

💡 Quick Tip: Borrow from the men’s section for a truly oversized fit — the proportions are better, the fabric is often softer, and the price is usually lower.

3. Cream Waffle-Knit Henley With Boyfriend Jeans

Waffle-knit henleys are having a quiet moment, and they deserve it. The textured weave adds visual interest to the simplest outfit, and the button placket gives you styling options — buttoned up for polish, open for a relaxed V.

A cream henley with loose boyfriend jeans is soft, neutral, and effortlessly pretty. Roll the jeans once at the ankle, add cream or tan sneakers, and you’re done. It’s the kind of outfit that looks good in every lighting, which matters when the holiday photos start.

This is also a fantastic base layer. Throw a plaid scarf or a chunky cardigan over it when the temperature drops, and the whole look levels up.

4. Black Hoodie Dress and Chunky Sneakers

A hoodie dress is the ultimate “I woke up like this (but cute)” garment. In black, it reads sleek rather than sporty — especially with the right styling. The key is the fit: it should skim your body, not drown it.

• Dress: Black, hitting mid-thigh, with a proper hood (not a sad flat one).
• Shoes: Chunky white or cream sneakers for contrast.
• Legs: Bare for mild days, fleece tights when it’s freezing.

Add a long pendant necklace and a crossbody bag, and you’ve got an outfit for casual holiday outings that took three minutes. Add a red beanie, and it’s suddenly festive.

5. Soft Plaid Pajama Set Styled for Christmas Morning

Christmas morning has a dress code, and it’s pajamas — but the good pajamas. A soft plaid pajama set in red, green, or a classic tartan, in brushed cotton or flannel, is as much a part of the holiday as the tree itself.

The upgrade from “old pajamas” to “Christmas morning pajamas” is all in the details: a proper button-front top (not a stretched-out tee), matching bottoms, and fuzzy socks or slippers. If you’re hosting or being photographed, add a cozy robe in a complementary solid.

📌 Good To Know: Buy the set a size up for maximum coziness, and wash it once before the big day — flannel gets softer with every wash, and Christmas morning is no time for stiff fabric.

6. Ribbed Knit Co-Ord Set in Warm Taupe

Matching knit sets are the chic woman’s pajamas — they feel like loungewear but look like an outfit. A ribbed co-ord in warm taupe (that gorgeous brownish-grey neutral) is sophisticated, cozy, and endlessly versatile.

Wear the set as-is for maximum ease, or break it up: the top with jeans, the pants with an oversized sweater. The ribbed texture adds dimension that keeps a monochrome set from looking flat. Slippers at home, white sneakers if you venture out.

💡 Quick Tip: Taupe is a magical neutral — it pairs with black, cream, camel, burgundy, and forest green. One set, endless holiday combinations.

7. Vintage Band Tee, Cardigan, and Mom Jeans

Your favorite vintage band tee deserves a holiday outing too. Layer it under an open chunky cardigan — cream, grey, or even a deep red — with high-rise mom jeans, and you’ve got relaxed cool with a festive wink.

• Tee: The more worn-in, the better. A faded graphic is a feature, not a flaw.
• Cardigan: Chunky knit, worn open, sleeves pushed up.
• Jeans: High-rise mom fit, light or medium wash.

Finish with Converse or Vans and a messy bun. It’s giving “cool aunt at Christmas dinner,” and that’s a role worth playing well.

8. Oversized Denim Shirt and Black Leggings

An oversized denim shirt worn as a tunic over black leggings is one of those outfits that’s so simple it feels like cheating. But the proportions — long and loose on top, sleek on the bottom — are genuinely flattering.

Leave the shirt untucked and unbuttoned at the cuffs, with the sleeves scrunched. A long necklace adds a vertical line that elongates the whole look. Ankle boots dress it up; sneakers keep it casual.

For a holiday touch, add a red or plaid scarf, or swap the black leggings for deep burgundy ones. Small change, big seasonal energy.

9. Cable-Knit Sweater Dress Worn as a Tunic Over Leggings

That cable-knit sweater dress that’s slightly too short to wear alone? It’s a perfect tunic. Worn over black leggings with the hem hitting mid-thigh, it becomes a cozy, flattering outfit that works for everything from church to couch.

The cables add texture and visual interest, so keep everything else simple: black leggings, black or brown boots, minimal jewelry. A wide belt over the dress can define the waist if you want more shape.

📌 Good To Know: The tunic-over-leggings ratio matters — the top should cover your hips and hit mid-thigh. Too short and it’s awkward; too long and it swallows the leggings entirely.

10. Fleece-Lined Flannel and Joggers for Movie Night

Christmas movie marathons are sacred, and they require appropriate attire. A fleece-lined flannel shirt — the warmest, softest thing you own — with matching or coordinating joggers is the official uniform of holiday movie night.

• Flannel: Fleece-lined, in a cozy check. Button it up or wear it open over a thermal.
• Joggers: Soft fleece joggers in grey, black, or a coordinating plaid.
• Feet: The fuzziest socks you own. This is not the time for real shoes.

Add a throw blanket, hot chocolate, and zero plans to leave the house. Perfection doesn’t need styling.

11. Longline Cardigan Over a Camisole and Wide-Leg Jeans

A longline cardigan — hitting at or below the knee — is like wearing a hug, and it instantly makes a simple camisole and wide-leg jeans feel styled. The long vertical line of the cardigan is also incredibly elongating.

Choose a cardigan in a soft neutral (oatmeal, grey, camel) with some texture — a chunky cable or a soft bouclé. The cami underneath can be silk for polish or cotton for ease. Wide-leg jeans in a medium wash keep the whole thing modern.

This is a wonderful “working from home during the holidays” outfit — comfortable enough for the couch, presentable enough for a video call. Just add earrings and you’re camera-ready.

12. Red Beanie, Puff-Sleeve Sweater, and Dark Jeans

Sometimes one accessory makes the outfit. A red knit beanie — classic, cozy, unmistakably Christmassy — paired with a cream or ivory puff-sleeve sweater and dark jeans is adorable without trying too hard.

The puff sleeves add a romantic, feminine touch that balances the casual beanie and denim. Keep the sweater’s neckline simple (crew or scoop), and let the sleeves be the detail. Dark jeans and ankle boots ground the sweetness.

💡 Quick Tip: A beanie with a folded brim suits most face shapes. If yours is slouchy, wear it slightly back on your head rather than pulled low — it opens up your face and looks more intentional.

13. Chambray Button-Down Tied at the Waist Over a Midi Skirt

Here’s a styling trick that works every time: take a chambray button-down, tie it at the waist over a midi skirt, and suddenly you have a defined silhouette with zero effort. The knotted shirt adds a casual, youthful energy to the skirt’s elegance.

• Shirt: Light-wash chambray, oversized enough to tie comfortably.
• Skirt: A-line or pleated midi in black, burgundy, or a holiday plaid.
• Shoes: Ankle boots or clean sneakers, depending on the vibe.

Leave the top few buttons undone and roll the sleeves. It’s relaxed, it’s flattering, and it works for everything from shopping to casual dinners.

14. Quilted Vest Over a Thermal and Straight Jeans

The quilted vest is the unsung hero of transitional winter dressing. Worn over a fitted thermal or long-sleeve tee with straight jeans, it’s warm where it counts while keeping your arms free — perfect for active holiday days.

Choose a vest in black, navy, or olive for versatility, or a deep red for holiday spirit. The thermal underneath should be thin and fitted to avoid bulk. Add a plaid scarf and beanie when it’s truly cold.

This is the outfit for Christmas tree cutting, winter walks, and any outdoor tradition. Practical, warm, and genuinely cute — the holy trinity of relaxed holiday dressing.

15. Slouchy Turtleneck With Faux-Leather Leggings

A slouchy turtleneck in cream, grey, or black paired with faux-leather leggings is the perfect tension between cozy and cool. The soft knit on top, the sleek leather-look on the bottom — it’s an outfit with built-in contrast.

The turtleneck should be genuinely slouchy — a loose funnel neck rather than a tight roll. Let it drape. The leggings should be high-waisted and matte rather than shiny for a more expensive look. Ankle boots or heeled booties complete the outfit.

📌 Good To Know: Faux-leather leggings and a chunky knit is also a brilliant travel outfit — comfortable for long journeys but polished enough to walk straight into a holiday gathering.

16. Striped Turtleneck, Denim Overalls, and Booties

Denim overalls are pure joy, and they’re surprisingly great for the holidays. Layer a striped turtleneck underneath — navy and white, or red and white for extra festivity — add ankle booties, and you’ve got playful, comfortable, utterly charming.

• Overalls: Classic medium-wash denim, relaxed fit, cuffs rolled once.
• Turtleneck: Thin striped knit that layers smoothly underneath.
• Booties: Brown or black ankle boots with a low heel.

Leave one strap undone for a carefree vibe, or keep both buckled for polish. Either way, you’ll be the most comfortable person at the cookie exchange.

17. Knit Poncho Over Jeans and Knee-High Boots

The poncho is back, and honestly, it never should have left. A soft knit poncho — in cream, grey, or a festive red — thrown over jeans and knee-high boots is dramatic, cozy, and incredibly easy to wear.

Because the poncho adds volume up top, keep everything underneath streamlined: skinny or straight jeans, fitted top, tall boots. The poncho should hit around the hip — too long and it overwhelms, too short and it looks like a capelet.

💡 Quick Tip: Add a thin belt over the poncho at your waist to create shape. It’s a small styling move that transforms the silhouette from shapeless to intentional.

18. Relaxed Linen-Blend Shirt, White Jeans, and Loafers

Not everyone spends Christmas in the cold. If your holidays are warm-weather affairs, a relaxed linen-blend shirt in white or soft red with white jeans and leather loafers is breezy, elegant, and perfectly festive.

• Shirt: Linen or linen-blend, slightly oversized, sleeves rolled.
• Jeans: White or cream, in a relaxed straight fit.
• Shoes: Tan or cognac leather loafers — no socks needed.

Add gold jewelry and sunglasses, and you’re ready for a Christmas brunch on the patio. Holiday dressing is about the spirit, not the sweater.

19. Sherpa-Lined Denim Jacket, Tee, and Black Jeans

A sherpa-lined denim jacket is winter’s greatest multitasker — the denim keeps it classic, the sherpa keeps you warm, and together they’re the perfect topper for the simplest outfit underneath. A plain tee (white, black, or red) and black jeans is all you need.

The jacket is the whole look, so make sure it fits well through the shoulders — sherpa adds bulk, and you don’t want to look swallowed. Leave it open to show the tee, add a beanie and boots, and you’re ready for anything December throws at you.

This is also a fantastic layering piece for unpredictable weather. Warm enough for a chilly evening, easy to tie around your waist if the afternoon warms up.

20. Cozy Sock-and-Slipper Look: Knit Dress and a Robe Cardigan

We end where the best holidays happen: at home. A soft knit dress — nothing structured, just comfortable — with a long robe-style cardigan belted loosely over it, plus your favorite fuzzy socks or slippers, is the ultimate relaxed Christmas look.

The robe cardigan is what elevates this from “loungewear” to “outfit”: the belt defines your waist, the long line looks elegant, and the whole thing feels intentional. Choose the dress and cardigan in coordinating neutrals — cream and camel, grey and charcoal — for a pulled-together feel.

📌 Good To Know: This is the perfect host outfit. You’ll be comfortable cooking, comfortable on the couch, and you’ll look lovely in every photo — which, on Christmas, is what really matters.

CONCLUSION

Relaxed Christmas style is about honoring what the season is really for: comfort, warmth, and being present. Choose soft fabrics, easy layers, and outfits that let you actually enjoy the holidays.
