Assess our consumption habits and their environmental impact.
Identify areas where we can make more sustainable choices in the coming year.
Celebrate the progress we've made towards a more conscious lifestyle.

December 2025: Conscious Holiday Style That Lasts:
December dressing in 2025 is not about a new outfit for every event, and more about elevating what already works with what you already own. Think: one great coat, a statement knit, a versatile dress, and accessories that shift the mood from daytime market to midnight toast—all grounded in better materials and built with better systems.
Key themes that showed up across collections and street style:
Cozy eco-luxury (recycled and regenerative cashmere, wool, velvet.[4][8][2]
Circular and secondhand holiday looks, supported by robust resale and repair programs.[5][6][7][11]
Minimalism with modular layering—pieces that restyle easily across events and into 2026.[3][9][2]

Cozy eco-luxury: regenerative wool & better cashmere:
The heart of December style is tactile: knitwear, outerwear, and soft tailoring that feel indulgent and responsible at once.
Brands to know and study:
Gabriela Hearst – Luxury recycled cashmere coats, skirts, and sweaters with full traceability and a strong circular design ethos—ideal for polished holiday suiting and outerwear.
Pangaia – Recycled and regenerative cashmere sets and winter basics, often in nature-inspired hues that align with the season’s earthy palette.
NAADAM – Ethically sourced Mongolian cashmere at accessible price points, great for “forever” sweaters, scarves, and gifts.
Reformation – Recycled cashmere tops and dresses that lean into party silhouettes while staying aligned with lower-impact materials.
The Sweatshirt by Sheep Inc
On the wool front, regenerative stories are moving from niche to increased public awareness:
Allbirds – Knit sneakers and layers built on a public commitment to regenerative wool by 2025, plus product-level carbon footprint labeling that invites transparency into the conversation.
Sheep Inc. – Carbon-negative knitwear made from 100% regenerative material, with timeless, minimalist shapes that work from December through the rest of the year.
Circular holiday dressing: repair, resale & re-wear:
One of the most exciting shifts this December is how people access clothes. Instead of defaulting to fast, festive buys, more shoppers are choosing resale, rental, and upcycling.[6][7][11][3][5]
Circular leaders to learn from:
Patagonia – Worn Wear – Trade-in, resale, and repair for outdoor layers and fleece; perfect for anyone refreshing winter gear or leaning into cozy cabin aesthetics.
Levi’s – Integrated repair, resale, and more recyclable WellThread denim lines, plus strong vintage programs that keep jeans and jackets in circulation.
The North Face Renewed – Refurbished TNF garments—from puffers to shells—extend the life of technical pieces.
Tentree – Circular design backed by tree-planting, with take-back and recycling powered by SuperCircle to close the loop on everyday basics.
Lululemon Like New and other circular programs – Featured in 2025 circular-fashion rankings as brands investing in structured resale and recycling as part of their core model.[19][20]
From repair to reinvention: mending, alterations & upcycling:
Repair and visible mending are no longer niche—it's becoming more accessible, with mending workshops happening around the globe. Repairing or altering a garment can be an integral part of how you prepare for holiday dressing in 2025.
Brand repair & take-back programs:
RE.UNIQLO STUDIO (UNIQLO) – In-store repair and visible mending for denim, knits, and outerwear, helping customers keep winter staples in rotation.[21]
ARKET x SOJO (UK/EU) – Integrated repair and alteration service, offered in-store and via SOJO’s door-to-door model, ideal for tailoring holiday coats and occasionwear.[22]
Reformation “RefRecycling” – Take-back channel turning used Ref garments into store credit while feeding recycled fiber into future pieces.[26]
📦 Online Repair & Alterations
Mail-in repair services – Online platforms (highlighted by sustainable fashion guides) mend knits, zippers, and seams without a shop visit—especially helpful in December.[23]
Digital alteration platforms – Book hems, fit tweaks, and repairs online; schedule pick-up or shipping for last-minute holiday tailoring.[24]
Christmas Sweater
✂️ Community Upcycling & Workshops
Holiday upcycle events – “Upcycled Ugly Holiday Sweater” and party-wear workshops where you bring existing garments and learn to embellish or rework them.[25]
Repair & alteration classes – Short courses and studio sessions that teach mending, basic tailoring, and upcycling skills.
Why ifd Highlights These
These services extend garment life, reduce holiday-season overconsumption, and give both designers and consumers hands-on experience with circular fashion and mindful styling—values at the heart of this community.
Minimalism, modular dressing & “less but better.”:
Silhouette-wise, December 2025 leans hard into modularity: a small, thoughtful wardrobe that can do a lot. Brands like Everlane and Cuyana exemplify this with versatile, mix-and-match pieces designed for long-term wear and multiple styling options, supporting the 'less but better' philosophy.
Brands embodying the “less but better” mindset:
Everlane – Neutral tailoring, refined wool coats, and knit dresses made to mix, match, and repeat across work, travel, and celebration.
Cuyana Cuyana – “Fewer, better” coats, dresses, and leather accessories positioned as long-term investments rather than seasonal splurges.
Quince – Direct-to-consumer cashmere, silk, and wool basics at more accessible prices, supporting minimalist winter capsules that still feel special for the holidays.
For designers, this trend is less about stripping back creativity and more about designing for repeat wear—pieces that can carry multiple styling stories across a single month.
Why this matters to the Inside Fashion Design community
These December "trends" and featured brands aren’t just “what’s in”—they’re case studies in how ethics, aesthetics, and systems thinking come together. Looking at brands like Gabriela Hearst, Sheep Inc., Patagonia, and Tentree gives designers concrete examples of:
how materials choices (recycled, regenerative, traceable) change the story of a garment,
how circular models (repair, resale, take-back) extend impact far beyond the point of sale
how minimalist, modular design supports real people’s lives rather than encouraging endless churn.
Color Story: December 2025
December 2025 color is warm, grounded, and quietly festive—perfect for conscious wardrobes that need to work beyond a single season.
1. Grounded earths & chocolate tones
Core colors: terracotta, rust, curry mustard, camel, and rich chocolate browns.
Sustainable angle: these “earth-rooted” shades age gracefully and pair well with existing neutrals, making them ideal for investment coats, boots, and recycled-cashmere knits.
2. Soft, poetic neutrals
Core colors: pearl grey, “cumulus cloud” off-white, putty beige, soft stone.
Sustainable angle: minimalist capsule pieces (slip dresses, knit sets, tailoring) in these tones become high-rotation items, supporting “less but better” wardrobes and modular holiday dressing.
3. Forest greens & deep blues
Core colors: forest and moss greens, sapphire and crown blues, inky midnight tones.
Sustainable angle: nature-linked hues are an easy storytelling bridge to regenerative wool, recycled fibers, and farm-to-fashion narratives—great for brands like Allbirds, Sheep Inc., Pangaia, and Gabriela Hearst.
4. Jewel accents & optimistic brights
Core colors: fig and plum, vibrant poppy red, “salted lime” and citric greens, amber-y metallics.
Sustainable angle: use these as accent layers—scarves, bags, a single knit or shoe—rather than full new outfits, which makes it easier to shop secondhand, upcycle, or choose one consciously-made “statement” piece that can rotate for seasons.
5. Low-key shimmer
Core colors: bronze mist, soft gold, champagne, gunmetal.
Sustainable angle: subtle metallics on accessories or trims (instead of fully sequined looks) keep holiday outfits photogenic while staying wearable for non-festive occasions, reducing single-use party buys.
How to Introduce New Colors Using What You Already Own:
Start with chocolate + your existing neutrals: Pair a chocolate-brown sweater or blazer with black, navy, or denim you already have for an instant 2025 update without a full new look. If you’re not buying new garments, try adding a brown belt, boot, or bag to ground lighter pieces already in your closet.
Forest Green Cardigan mage by Start by WGSN Add forest green as an accent: Layer a forest-green knit, scarf, or tights under/over your existing blacks, creams, and greys for a subtle but very “now” palette shift. Upcycle: dye or over-dye a faded sweatshirt or cotton dress in a deep green to refresh something you already own instead of replacing it.
Use sapphire and midnight blues for evening: Swap your default black top or blazer for a deep sapphire or midnight blue—then style it with the same trousers, skirts, and jewelry you already use for nights out. If budget is tight, look for secondhand silk or satin in these blues and pair with existing neutral bottoms.
Accent color bag mage by Start by WGSN Test brights in micro-doses: Bring in poppy red or “salted lime” through one piece—like a turtleneck layered under a neutral dress, or a single bright bag or shoe—so the rest of your outfit can be items you already own. Try a DIY update: add bright buttons, visible mending, or contrast stitching to a neutral cardigan or coat for a low-impact color lift.
Silver Metallic boots mage by Start by WGSN Keep metallics to trims & accessories: Choose bronze or champagne in belts, jewelry, hair accessories, or a clutch instead of whole sequined garments, so those pieces can work beyond December. Re-style: pair existing metallic shoes or bags with new grounded combinations (chocolate + forest, navy + pearl) to make them feel current again.
December is often framed as a month of excess, but we can tell a different story—one of warmth, intention, and care. The designers and brands leading the way are proving that style and sustainability can support each other beautifully, from regenerative wool and recycled cashmere to circular services, repair studios, and color stories that will still feel right well into 2026.
At Inside Fashion Design and The Conscious Fashion Design Academy, this is exactly the space we love to explore with you: where trends become tools, not pressure; where materials and systems matter as much as silhouettes; and where your own creativity and values shape what’s next. Whether you are designing a collection, curating a closet, or planning your next business move, consider this December an invitation to experiment—repair something, upcycle a piece, try a new color with what you already own, or dig deeper into circular design and ethical sourcing through our courses and community.
The holiday season will come and go, but the skills, stories, and conscious choices you practice now can carry forward into every season that follows.
