Coastal Grandmother Is Back: Fall's Coziest Aesthetic Returns

The seaside sweater set is back in charge. Coastal Grandmother — the relaxed, knitwear-heavy aesthetic that swept TikTok in 2022 — has resurfaced for autumn 2026 with a noticeably louder attitude. The autumn and winter catwalks were saturated with on-theme looks this season, according to Hello Magazine, trading the look's original restraint for clashing colours, hefty textures and unexpected layering. Quiet luxury's reign over fall dressing appears to be over.

First, a refresher. The term was coined on TikTok four years ago as shorthand for the wardrobe of the heroines of Nancy Meyers films: the whitewashed Hamptons kitchen in Something's Gotta Give, translated into clothing. The original codes were linen shirts, oversized button-ups and blue-and-cream palettes — escapism dressing built on a fantasy of slow mornings and sea air.

How the runways made it eccentric

The 2026 revival is not a straight rerun. On the Milan and Paris runways, designers dialled the volume up. Dries Van Noten sent out kitschy, colourful knits teamed with duffle coats, thick socks and longline shirts; Tod's opted for oversized raincoats in vibrant mustard; Prada paired knee-length skirts with sunset-hued crocheted scarves; and Chloé showed heavily shouldered tailoring with floral blouses and flouncing skirts, according to Hello Magazine's runway report. The front-row message: texture is the story.

Off the runway, the look has a celebrity standard-bearer. Katie Holmes has spent weeks on the streets of New York in this register — slouchy knits, easy trousers and unpretentious layers that read as eclectic rather than effortful.

The word the fashion press keeps reaching for is eccentric. As one fashion roundup put it this week: "Farewell 'quiet luxury,' chunky knitwear, clashing colours and unexpected layering are making waves this season." Where the 2022 version was about blending in beautifully, This season's Coastal Grandmother is about standing out cosily — plaids next to crochet, mustard next to navy. If quiet luxury was a whisper, this is a warm conversation.

Why comfort keeps winning

There is data behind the feeling. Trendalytics' roundup of this year's biggest TikTok fashion trends names ten defining looks — office siren, coastal cowgirl, blokette, a nineties grunge revival, gorpcore and dark academia among them — and notes that clean-girl minimalism is the one visibly fading. The direction of travel is unmistakable: away from restraint, toward texture and personality.

It also has a durability advantage most viral aesthetics lack. The look "has evolved from a micro-trend into a broader aesthetic direction," according to style analysts at eyewear retailer Glasses Direct, who credit its emphasis on timeless quality and understated confidence. That is the opposite of the Ball Hog Aesthetic currently circulating on fashion TikTok — stealth designer pieces that read as basics — which depends on rare archival finds. The seaside-knit look can be assembled from thrift racks and hand-me-downs, and it arguably looks better that way.

The same instinct is showing up beyond clothing. Our recent coverage of Gen Z fragrance habits found that scent has quietly overtaken makeup as the generation's most consistent daily ritual — invisible, personal and worn every day. The parallel home trend even has its own name: Grandma Core, the dark-wood-and-lace-curtain interior movement, is built from the same nostalgia for collected, lived-in warmth.

The honest counterpoint: fashion TikTok cycles through labels at a ruthless pace, and a named aesthetic can burn out online before most people wear it once. The saving grace is that the pieces are genuinely useful — a good duffle coat and a fairisle cardigan will serve you through many winters regardless of what the trend is called next spring. Buy the knit, not the name.

How to wear it on a real budget

Styling it is mostly a layering exercise. Start with a chunky knit — a cable-knit or fairisle cardigan worn open over a floaty midi dress carries a summer favourite into cold weather. Add a duffle coat with its toggle fastenings, thick socks with loafers or boots, and a tartan or pleated midi skirt for pattern. Keep the palette in the family — cream, navy, sand, oatmeal — plus one clashing accent like mustard to keep it 2026 rather than 2022.

The cheapest entry point is the one the aesthetic practically demands: secondhand. Charity shops and resale apps are full of the wool-blend knits, striped tops and canvas totes the look is built on. Look for natural fibres and relaxed cuts, skip anything with a high-gloss factory finish, and let pieces look collected over time rather than bought in one trip.
