After a few years of very polished, very clean dressing, the look I'm seeing everywhere now is the opposite: clothes that seem pulled from a grandfather's closet. The eclectic grandpa trend mixes vintage menswear, a bit of retro streetwear and some academic charm. Knit vests over crisp button-downs, corduroy trousers, roomy cardigans, chunky loafers, and patterns and textures that shouldn't work together but do. I like it because it rewards comfort and character over perfection, and because most of the pieces turn up secondhand for very little. You can go all in or add one or two pieces to what you already wear. The 20 outfits below show both, with the fit and fabric notes I'd give anyone trying it.
Thrifting Grandpa Pieces That Actually Fit
Most of this look comes from the men's racks of secondhand shops, which is half the fun. Menswear is cut differently, though, so I check a few things before anything goes in the basket.
- Shoulders first. Blazers and coats can be shortened at the sleeve, but shoulders are expensive to alter. A seam that sits an inch past your own shoulder looks relaxed; much more looks borrowed.
- Read the fabric label. Wool, lambswool and cashmere age well; acrylic pills and goes limp. A high wool percentage is worth paying a little more for.
- Hold knits up to the light. Moth holes hide at the elbows, cuffs and along the hem, and tiny ones grow once the knit is worn.
- Check trouser rise. Older men's trousers often have a higher rise and front pleats, which suit this look, but the hips run narrower than most women's cuts.
- Expect long sleeves. Rolling a shirt or cardigan sleeve is part of the style, so a sleeve that's too long is rarely a dealbreaker.
Wash or air out anything secondhand before you wear it. Wool can be hand washed cold and dried flat, and a day hanging outside clears most of the musty smell.
1. Knit vest with button-down shirt and pleated trousers
A chunky knit vest over a crisp white button-down is the trend's unofficial uniform. The shirt collar showing above the vest's neckline is what gives it the look, so pick a shirt with a collar that sits flat and doesn't curl. Tuck it into high-waisted pleated trousers in oatmeal or charcoal; front pleats add room at the hip, which is why they suit curvy figures better than flat fronts often do. Penny loafers with white socks on show add a preppy note. Tortoiseshell glasses and a leather satchel complete it for office days and café afternoons. If you only try one outfit from this list, start here.
2. Oversized chunky cardigan with straight-leg jeans
A chunky oversized cardigan feels like it's been in the family for decades, and that's the point. Mustard, olive or rust with big buttons and a roomy cut looks right. Wear it over a plain white or cream tee with medium-wash straight-leg jeans to keep the bottom half simple. Heavy cardigans stretch on a hanger, so fold yours on a shelf between wears. Roll the jeans once and add retro sneakers or flat loafers. A canvas tote and a little gold jewelry finish it for errands, farmers' markets and slow brunches. It sits halfway between grandma and grandpa, which is part of its charm.
3. Tweed blazer with turtleneck and corduroy trousers
A tweed blazer over a fine-knit turtleneck looks like it belongs in a well-stocked library. Choose a slightly oversized blazer in herringbone or houndstooth, and a slim black or cream turtleneck that sits close to the neck. Thin knits matter here; a thick turtleneck under tweed makes the shoulders bulky and the collar ride up. Wide-leg corduroy in chocolate brown or forest green brings a third texture. Loafers or lace-up oxfords and an old leather-strap watch suit it, with a structured crossbody for a modern note. It covers a cold morning commute and an afternoon in a bookshop.
4. Argyle sweater with wide-leg trousers and penny loafers
Argyle is back, and it brings grandpa charm in the best way. A relaxed argyle sweater in navy, maroon and forest green looks most authentic. Tuck just the front into high-waisted wide-leg trousers in beige or camel. Argyle is a busy pattern, so I keep everything else plain: a simple black leather belt, a fine chain and a slim watch. Penny loafers suit it, and a chunky sole updates the look. Wool argyle pills under the arms and where your bag rubs, so a sweater comb is worth having. The mix of preppy pattern and modern trouser shape is what keeps it from looking like a costume.
5. Quilted jacket with floral midi dress and ankle boots
Mixing tough and soft pieces is one of the easiest ways into this style, and a quilted barn jacket over a floral dress does exactly that. A lightweight quilted jacket in olive or tan suits a midi dress with a small vintage print. Keep the jacket short, ending at the hip, so the dress still shows below it. Brown leather ankle boots with a low block heel ground it, and a printed silk scarf at the neck or in your hair adds color. A leather crossbody finishes it for brunch or a gallery visit. Quilted jackets are warm but not waterproof, so a light shower is fine and a downpour is not.
6. Oversized cable-knit sweater with Bermuda shorts and loafers
An oversized cable-knit sweater with tailored Bermuda shorts is for early spring, when the weather can't decide. Start with a thick cable knit in ivory or soft gray, and pair it with Bermudas in khaki or a quiet plaid. Proportion is the whole trick: the heavy top balances the shorter hem, but only if the shorts end just above the knee. Any shorter and the sweater swallows them. Loafers with ribbed socks pulled up, round retro sunglasses and a top-handle bag finish it. It's grandpa on vacation, with legs that are a little chilly and a top that's warm.
7. Corduroy shirt jacket with white tee and relaxed slacks
A corduroy shirt jacket worn open over a plain white tee gives this trend its borrowed-from-the-boys feel. The cord looks lived-in right away. Pair it with relaxed tailored slacks in camel or tobacco that taper slightly at the ankle, so the jacket's volume isn't repeated all the way down. Wide-wale cord looks more rugged, fine-wale more polished. Retro dad sneakers keep it comfortable for a long city day, and a vintage baseball cap in your bag adds a sporty throwback. It suits casual Fridays and weekend coffee runs.
8. Striped button-down under sweater vest with relaxed jeans
A thin striped button-down under a solid crewneck vest is a classic grandpa move. Let the collar and cuffs show. A warm neutral like oatmeal or caramel suits most stripes. The shirt must be thin; a heavy oxford under a vest bunches at the armholes and ruins the line. Relaxed light-wash jeans that sit comfortably at the waist, cuffed once, keep it casual. Retro sneakers or flat loafers, a woven leather belt and small gold hoops soften the menswear. It has an easy intellectual feel for days when you want to look smart and stay comfortable.
9. Fair Isle knit with A-line skirt and knee-high boots
A Fair Isle sweater brings cabin warmth to the look. I'd pick one with a classic Nordic-inspired pattern in muted cream, navy and rust, since bright versions tip quickly into holiday-sweater territory. Tuck it loosely into a structured A-line mini in black or chocolate brown, so the busy top meets a clean bottom. Real Fair Isle is stranded knitting, with floats of yarn on the inside that can catch on rings and watches, so take care putting it on. Flat or low-heeled leather knee-high boots and opaque tights keep you warm. A simple crossbody and silver jewelry finish it.
10. Flannel shirt with cargo pants and dad sneakers
A soft flannel shirt worn open over a fitted white tank or tee brings out the rugged, outdoorsy side of this trend. Red-and-black buffalo check is the classic choice; muted green and navy plaid is quieter. Relaxed cargo pants in olive or khaki add the utilitarian pockets. Because both pieces are loose, the tank underneath needs to be fitted, or the outfit loses all shape. Chunky retro dad sneakers anchor it. Roll the flannel sleeves and add a beanie or old baseball cap on cold days. It's made for road trips and lazy Sundays.
11. Wool pleated midi skirt with slouchy turtleneck and loafers
A heavy wool pleated midi in a classic tartan or solid charcoal is the most elegant piece in this wardrobe. Pair it with a slouchy turtleneck in cream or heather gray, tucked at the front only, so the pleats fall from the waist. Wool pleats hold their shape far better than polyester, and they move when you walk, which is why the skirt looks good in person. Size the skirt for your hips so the pleats lie flat instead of splaying open. Chunky lug-sole penny loafers with visible socks, a structured leather bag and a silk scarf in your ponytail finish it.
12. Vintage graphic tee under a blazer with wide-leg jeans
This outfit is where eclectic grandpa meets retro streetwear. Start with a worn-in vintage graphic tee, such as a faded band logo or an old sports print, and put an oversized boxy blazer in tweed or wool over it. The casual tee against the tailoring is what makes it work. Wide-leg dark-wash jeans should just break over chunky loafers or retro sneakers; too much puddling looks sloppy rather than relaxed. Tortoiseshell sunglasses, a slouchy leather shoulder bag, a few gold chains and an old watch finish it. It's a little edgy and a little polished, good for dinners and gallery openings.
13. Knit cardigan with slip dress and ballet flats
A long knit cardigan over a silky slip dress shows how well this trend plays with texture. Choose an open-front fine-gauge cardigan and a satin midi slip in a related color, such as camel over champagne or olive over cream. A fine knit drapes over satin, while a chunky one pulls the slip's straps and makes it twist. Flat ballet shoes or simple Mary Janes keep it delicate. A thin chain or one strand of pearls is enough. It suits in-between weather and date nights, when you want to look elegant and still feel wrapped up.
14. Tweed vest with ruffled collar blouse and tailored trousers
A tailored tweed vest buttoned over a blouse with a ruffled or bow collar leans fully into vintage charm. The vest brings the menswear, and the blouse softens it. Pick a blouse in a light fabric so the ruffle sits on top of the vest's neckline instead of being squashed under it. Tuck it into high-waisted tailored trousers and add a thin leather belt. Pointed kitten heels or loafers both work, and pearl studs with a structured mini bag dress it up. It suits a creative office or a nice lunch. It's ladylike meets librarian, and it really does work.
15. Oversized bomber jacket with turtleneck and plaid trousers
The grandpa bomber is about character: a slightly worn, oversized jacket in muted olive or burgundy nylon. Over a thin cashmere or merino turtleneck in cream or black, it's warm without bulk. High-waisted plaid trousers in a subtle check balance the slouchy top. Check the bomber's ribbed hem; it should land at your hip, not your waist, or the jacket looks cropped and pulls the eye up. Chunky loafers or combat boots give it an edge, and a canvas backpack or leather messenger bag suits the bookish mood. It's cozy enough for cold days and has that thrifted feel the trend thrives on.
16. Cable-knit sweater with midi slip skirt and chunky loafers
A hefty cable-knit in oatmeal or soft sage tucked loosely into a silky midi slip skirt is the strongest texture contrast on this list. The skirt should skim the body and end just below the calf. Tuck only the front of the sweater and add a slim leather belt over the join, because a heavy knit fully tucked into a fluid skirt creates a bulge at the hip. Chunky lug-sole loafers add weight to the light skirt, and contrasting socks give the grandpa twist. A small shoulder bag completes it for brunch, date nights or a gallery afternoon.
17. Patterned bowling shirt with Bermuda shorts and retro sneakers
A vintage-style bowling shirt in a bold pattern or color block is a nod to grandpa's weekend wardrobe. Wear it untucked and slightly open over a white tank or fitted crop top. Bowling shirts are cut boxy and straight at the hem, so they look best ending at the hip; a longer one swamps shorts. Tailored Bermudas in beige or olive, just above the knee, keep it neat. White or cream retro sneakers with a colorful accent, round sunglasses, a simple chain and a woven tote finish it. It's grandpa on holiday, made for summer weekends and outdoor markets.
18. Crochet vest over puff-sleeve blouse with wide-leg pants
A crochet vest in a bright, mixed palette adds a handmade feel. Layer it over a crisp white cotton puff-sleeve blouse; the sleeves are what show, so choose a vest with deep armholes that won't crush them. Tuck the blouse into high-waisted wide-leg pants in linen or cotton, picking a color from the vest. Crochet stretches if hung, so store it folded. Flat leather sandals or woven mules keep it breathable for warmer days. A beaded necklace or a vintage brooch pinned to the vest adds personality, mixing grandma craft with grandpa ease.
19. Grandpa cardigan with floral midi skirt and Mary Janes
An embroidered or textured grandpa cardigan over a floral midi skirt is the romantic side of the trend. Look for small vintage details like embroidered flowers, pearl buttons or a scalloped collar, and wear it over a simple tucked tank or tee. The skirt should be flowing, midi-length and printed with a small floral, like old wallpaper. Keep the cardigan short enough to end at the waist so the skirt's shape shows. Leather Mary Jane flats or low block-heel pumps keep it walkable. A silk headscarf and a woven basket bag finish it for spring picnics and garden parties.
20. Relaxed-fit suit with a vintage tee and sneakers
For the high-low eclectic grandpa power move, take a relaxed matching suit in linen, cotton twill or light wool and skip the formal shirt. Put the blazer over a worn vintage tee, an old band shirt or a faded college logo. Keep the trousers loose and slightly cropped so they clear the top of the shoe, and wear clean retro sneakers or chunky trainers. A relaxed suit should still fit at the shoulder; if the shoulder seam drops down your arm, it looks borrowed instead of chosen. Add a baseball cap and tote for a streetwear lean, or keep it to sunglasses and a watch.
Mixing Argyle, Plaid and Fair Isle in One Outfit
The trend celebrates clashing patterns, but there's a difference between clashing on purpose and simply looking like you got dressed in the dark. Pattern mixing works when the pieces share something.
Change the scale
Pair one large pattern with one small one: a big buffalo check with a fine pinstripe, a bold argyle with a tiny houndstooth. Two patterns of the same size compete for attention and blur together.
Repeat one color
If the rust in your Fair Isle sweater shows up again in a plaid scarf, the eye reads the two as a set. Muted, earthy colors make this easier, which is part of why this style leans on browns, olives and creams.
Put a solid in between
A plain turtleneck, a solid vest or a pair of dark trousers gives patterned pieces room to breathe. I usually stop at two patterns per outfit, plus socks. Socks are the one place a third pattern almost always gets away with it, because they show in small doses.
Your Closet Already Has the First Grandpa Piece
Eclectic grandpa dressing has lasted longer than most micro-trends because it's built on comfort and character. It mixes old pieces with new ones and gives you room to play with pattern, texture and proportion. You can go all in with tweed blazers, knit vests and corduroy, or add a chunky cardigan and loafers to what you already wear. There aren't strict rules. Start with one piece that fits well, wear it with things you own, and add slowly as you find pieces with some history to them.
