Most women I dress in their forties and fifties already own a blazer they don't wear. Usually it's one of the stiff, boxy office jackets bought for a job years ago, and it fits the shoulders of a body that has since changed. Today's blazers come in softer fabrics and easier cuts: knit-backed crepe, linen, velvet, collarless and cropped shapes. Below are thirty full outfits, from a navy blazer with a white shirt to a printed jacket over a plain dress, each with what to wear underneath, on your feet and on your arm. For meetings, weekends and travel alike, I've noted where each one fits best and who might want to skip it.
When the Shoulders Fit but the Middle Doesn't
The most common fitting issue I see after 40 is a blazer that fits at the shoulder and pulls across the bust or middle when buttoned. Bodies change shape through the forties and fifties, and standard sizing doesn't always follow.
- If it fits the shoulders but strains at one button, try a one-button style with a lower button stance; it opens into a longer V that reads slimmer.
- Wear it open. Most blazers look better unbuttoned anyway, as long as the fronts hang straight rather than flaring out.
- Look for a little stretch in the fabric, such as wool with a small percentage of elastane or a knit-backed crepe.
- Check the upper arm. Sleeves that grip when you bend your elbow will feel worse by the end of the day.
If the shoulders are right, a tailor can usually let out or adjust the waist a little. If the shoulders are wrong, keep looking.
Length matters more than people expect, too. A hem that ends at the widest part of the hip draws a line straight across it. Moving the hem up to the high hip or down to cover the seat almost always looks better, so try two lengths side by side before you buy.
1. Classic Navy Blazer With White Button-Down And Tailored Trousers
Navy blazer, white shirt, dark trousers. It's the outfit I'd build first for anyone restarting a work wardrobe, because every piece goes with almost everything else you own. Choose black or charcoal trousers that skim the hip and fall straight. A slim leather belt marks the waist. Pointed flats or low block pumps. A structured tote and gold studs. The shirt collar can sit inside or over the lapel; worn over, it softens the look and frames the face.
2. Camel Blazer With Cream Turtleneck And Wide-Leg Trousers
Camel is one of the kindest colors near the face in your forties because it's warm without being yellow. A soft camel blazer over a thin cream turtleneck, with wide-leg trousers in camel or beige, makes one long column. Keep the turtleneck fine-gauge; a chunky one bulks up under the lapel and the jacket won't close. Suede mules or almond-toe flats and a crossbody a shade darker. A few fine gold rings. It works for lunch, a creative office or a gallery.
3. Black Single-Breasted Blazer With White Tee And Dark Denim
A black single-breasted blazer over a white crewneck tee and dark straight jeans is the weekend outfit I come back to most. Tuck the tee into mid or high-rise jeans so the waist shows under the open jacket. White leather sneakers or ballet flats, a black belt, a canvas tote and slim sunglasses. It takes five minutes and handles school pickup, groceries and brunch. Check the tee neckline: a stretched-out collar is what makes this look tired instead of easy.
4. Tweed Blazer With High-Waisted Jeans And Ankle Boots
Tweed adds texture without fuss if you pair it with something plain. A fitted tweed blazer in a neutral check or herringbone over a white or cream tank, with high-waisted rigid jeans in a medium wash. Rigid denim holds its shape under a heavier jacket better than very stretchy jeans, which can sag by afternoon. Brown or black stacked-heel ankle boots and a mini crossbody in oxblood or cognac. For farmers' markets, city walks and pub dinners in fall.
5. White Blazer With Striped Breton Shirt And Navy Trousers
A white blazer over a navy and cream Breton striped top has a French ease to it. Keep it from turning nautical-costume by using tailored navy trousers at the natural waist rather than sailor details. Roll the sleeves a little. Nude ballet flats or loafers, a straw or canvas bag, hoops and red lipstick. White jackets look sharpest in spring and early summer light. Check the stripe width: thinner stripes look more polished under a blazer than wide ones.
6. Bold Red Blazer With Black Turtleneck And Black Pencil Skirt
A red blazer is the boldest thing here, and it needs a quiet background. A slim black turtleneck and a knee-length black pencil skirt keep everything else calm. Sheer black tights and black suede pointed pumps continue the dark line down the leg. A slim clutch, silver or pearl drops, one bracelet. Before buying, hold the red to your face in daylight: blue-reds suit cool skin, orange-reds suit warm skin, and the wrong one makes you look tired. Wear it to a presentation or a holiday party.
7. Pastel Blazer With Floral Midi Dress And Nude Pumps
Lilac, blush or powder blue blazers over a floral midi dress in related tones make a soft outfit for spring events. The blazer's job is to give a floaty dress some shoulder and some structure. I'd pick a print with at least one shade from the blazer in it, so the two look planned. Nude pointed pumps, a pendant, pearl studs and a small top-handle bag. A spring wedding, a shower or a garden party.
8. Leather Blazer With Straight-Leg Jeans And Heeled Sandals
A leather blazer in a relaxed fit looks modern rather than rock-and-roll when everything around it is simple. Brown or black over a silk or modal tank, with medium-wash straight jeans. Strappy heeled sandals soften it. A slim belt and a sculptural bag. Real leather moulds to you over time, so a jacket that's snug across the back at first often eases; one that's tight in the shoulder won't. Good for date night or a gallery evening.
9. Oversized Gray Blazer With White Tank And Bike Shorts
Bike shorts under a blazer sound like a stretch for this age group, but I've seen it work well for weekends and travel days. The blazer has to be long-line and drapey, long enough to cover the top of the thigh. A fitted white tank and mid-thigh black bike shorts, white sneakers, a black tote, sunglasses and a cap. If you'd rather not show that much leg, the same blazer works with black leggings or slim cropped trousers. Choose thick, opaque shorts; thin ones go shiny and sheer when stretched.
10. Double-Breasted Blazer With Wide-Leg Dress Pants And Loafers
Double-breasted blazers give a lot of structure, so they suit days when you want to look in charge. Navy, charcoal or soft camel with peak lapels and a defined waist, over a silk shell or light knit, with matching wide-leg trousers. Black or burgundy penny loafers, a slim watch, a work tote and small gold hoops. Double-breasted adds an extra layer across the middle, so wear it buttoned only if it closes flat; if it pulls, it's the wrong size.
11. Houndstooth Blazer With Faux Leather Pants And Block Heels
Houndstooth in black and white or soft grays is pattern at its most controlled. Pair it with slim faux leather trousers in black or brown, so the woven wool sits against something smooth. A black silk shell or fine knit, black block-heel ankle boots and a quilted chain bag. Faux leather doesn't breathe well, so in a warm restaurant it can get uncomfortable; a looser straight leg helps. For drinks, a gallery or a concert in fall and winter.
12. Plaid Blazer With Pleated Midi Skirt And Knee-High Boots
A plaid blazer in muted olive, rust or deep blue has a bookish feel. I pull one solid color from the plaid for the sweater underneath, cashmere or merino in a fine gauge. A pleated midi skirt in a neutral softens the tailoring, and knee-high leather boots in black or dark brown keep it warm. The boot should reach just under the skirt hem so no shin shows. A crossbody and a slim watch for a book club gathering, a museum or brunch.
13. Beige Wool Blazer With Monochrome White Underlayer
Tonal dressing is one of the most flattering approaches I know for women over 40. A beige wool blazer over a white silk cami or fine white sweater, tucked into white or cream wide-leg trousers. The light base runs from neck to floor and the beige frames it. Cream loafers or low block sandals, a woven leather bag and gold jewelry. No logos, no prints, just good fabric. Whites and creams should share an undertone, or one will look dirty next to the other.
14. Gray Checkered Blazer With Charcoal Trousers And A Black Blouse
A small gray check in dove and charcoal reads professional without being dull. Over a black silk or crepe blouse with a soft neckline detail, tucked into slim charcoal trousers that stop at the ankle. Black pointed flats or low kitten heels, a black leather satchel and a sleek watch. It's the modern office uniform. Crepe blouses hold up better than silk through a long day of sitting; silk creases at the elbow and back.
15. Green Blazer With Straight-Leg Blue Jeans And Ballerina Flats
Green is a color many women overlook, and emerald, olive or forest look lively near the face without being loud. A single-breasted green blazer in soft wool or crepe over a white or ivory tee, tucked into straight blue jeans with a clean hem. Black or leopard ballet flats for a bit of fun. A leather tote and a gold necklace. Olive suits warm skin; emerald suits most people; forest can drain very fair skin in winter light. Lunch, shopping or an afternoon film.
16. Brown Blazer With Cream Slip Dress And Strappy Sandals
A chocolate brown blazer over a cream silk slip dress is one of my favorite contrasts here. The slip's drape softens the blazer's shoulders, and the brown and cream look richer together than black and white would. Fine ankle-strap sandals in nude or metallic, a mini top-handle bag in a warm shade, thin gold bracelets. A slip dress shows what's underneath, so a smooth, skin-tone layer under it is worth sorting out first. For summer weddings or an anniversary dinner.
17. Navy Blazer With Striped Tee And White Jeans
A navy blazer over a striped boatneck tee with white jeans is the outfit I'd pack for almost any city break. Roll the sleeves to show the wrist, tan sandals or espadrilles in warm weather, a rattan bag and tortoiseshell sunglasses. It makes packing for a vacation simpler, since the blazer also goes over a dress for dinner. White jeans need a thicker denim to avoid showing pocket linings, so check them in daylight.
18. Black Velvet Blazer With Silk Blouse And Black Trousers
Velvet catches light softly, which makes it one of the best fabrics for evening in winter. A black velvet blazer over a silk blouse in champagne, ivory or a jewel tone, with slim black trousers. Black velvet or patent pumps, a crystal clutch and drop earrings. It covers most cocktail invitations. Velvet marks easily if you sit on it for long, so I'd hang it the minute you're home and steam it lightly from the inside rather than ironing.
19. Khaki Linen Blazer With White Cotton Dress And Flat Sandals
A khaki or sand linen blazer is the most useful jacket for hot weather. Over a white cotton midi or knee-length dress, it's light and lets air through. Linen wrinkles, and I'd accept that as part of the look rather than fight it. Flat tan sandals with minimal straps, a woven straw bag, wooden bead earrings and a linen scarf on the handle. For outdoor concerts, market mornings and holidays by the sea.
20. Cropped Tweed Blazer With High-Waisted Wide-Leg Trousers
A cropped tweed blazer sits at the natural waist or just above, so it shows your shape without anything tight. With high-waisted wide-leg trousers in a solid neutral, the short jacket marks the waist and the trousers give length. A knit shell or silk blouse bridges the two. Pointed slingbacks and a boxy top-handle bag. If you're long in the body, cropped can look too short; try it with the trousers before deciding. Good for church services, brunch and daytime weddings.
21. Burgundy Blazer With Black Skinny Jeans And Heeled Boots
Burgundy is a soft way into color for anyone who lives in neutrals. A single-breasted burgundy blazer over a thin black turtleneck, with black high-waisted skinny or slim-straight jeans. Black suede heeled ankle boots give a little height and stay comfortable. A black crossbody and silver accessories keep it current. For evening, change the bag to a clutch and deepen the lip color. That's all it takes.
22. Cream Blazer With Printed Midi Skirt And Wedge Espadrilles
A cream blazer lets a printed skirt be the busy part of the outfit. A fitted cream blazer over a white tank or tee, with a printed midi in watercolor, abstract or a small floral. Tan wedge espadrilles, a straw clutch and gold hoops. Cream shows marks at the cuff and collar faster than you'd think, so I'd keep it for occasions rather than commuting. Bridal showers, garden parties and holiday dinners.
23. Boyfriend Blazer With Faux Leather Leggings And Sneakers
A boyfriend blazer is cut loose on purpose, which is why it works with something sleek below. Black, charcoal or navy, worn open over a fitted white or gray tank. Faux leather leggings or coated skinny trousers give shine. White low-top sneakers make it walkable all day, plus a leather backpack and very little jewelry. If leggings feel too exposed, a slim cropped trouser works with the same jacket. A shopping day, a travel day or a relaxed Friday.
24. Tuxedo Blazer With Cigarette Pants And Satin Camisole
A tuxedo blazer with satin peak lapels or contrast trim brings evening drama without looking like fancy dress. Over a satin or silk cami in ivory, blush or champagne, tucked into slim black cigarette trousers that brush the ankle. Black patent pumps and a jeweled box clutch. Pearls—a single strand or simple studs suit it best. Satin lapels mark easily with perfume and makeup, so dress first and spray last. Formal dinners and anniversaries.
25. Oversized Plaid Blazer With Sweater Dress And Knee-High Boots
An oversized plaid blazer over a fitted sweater dress feels warm without looking bundled. Espresso, burgundy or forest plaid, and a solid black, camel or cream dress underneath. The dress should be fitted so the big jacket has something slim to contrast with. Knee-high leather boots in a dark shade, a long pendant and a structured satchel. Holiday markets, casual Thanksgiving gatherings and weekend coffee.
26. Gray Herringbone Blazer With White Shirt And Dark Wash Jeans
Herringbone gives gray some depth while staying neutral enough for every season. A gray herringbone blazer over a crisp white shirt, tucked in for polish or left out for weekends, with dark straight jeans that hit the ankle. Brown loafers with a matching brown belt. A canvas tote and a watch. Herringbone wool sheds a little lint at first, so a clothes brush is worth keeping near the door. An everyday outfit for errands and catching up with friends.
27. Collarless Blazer With Silk Blouse And Relaxed Wide-Leg Jeans
Collarless blazers are softer than tailored ones, and I often suggest them to clients with a fuller bust or a shorter neck, since there's no lapel adding bulk at the chest. Sand, oatmeal or soft navy over a silk blouse in a related shade. Relaxed wide-leg jeans in a light or medium wash keep it casual. Neutral mules and a slouchy leather hobo. The open neckline is cooler in warm months too. It goes from a creative office to a weekend lunch without a change.
28. Pink Blazer With White Wide-Leg Trousers And Gold Accents
A dusty pink blazer is fresh without being sugary, especially with crisp white trousers. White wide-leg trousers that just touch the floor, with a white shell or cami underneath. Gold does the warming: a chunky chain, a slim gold watch and sandals with gold hardware. A white or tan structured bag. Dusty pinks with a little gray in them suit more skin tones than bright baby pink. For a daytime wedding or a spring luncheon.
29. Sleeveless Blazer Vest With Straight-Leg Trousers And Heels
A sleeveless blazer vest gives the shape of tailoring without the weight, which helps in warm offices and in spring and autumn. A long-line vest in cream, black or camel over a fine knit or silk shell, with straight-leg trousers in the same tone. One color from shoulder to shoe keeps the line long. Nude pointed heels, a slim belt and a structured clutch. Bare arms aren't for everyone; a thin long-sleeve knit underneath works just as well. Good for lunches, panels and gallery openings.
30. Printed Blazer With Solid-Colored Midi Dress And Woven Accessories
A printed blazer in painterly florals, abstract brushstrokes or a soft animal pattern needs a plain dress beneath it. Pick a dress in a color already in the print, and the outfit looks planned. Woven accessories, a rattan bag, braided leather sandals and wooden earrings, give it a relaxed texture. I'd keep jewelry minimal so the jacket stays the focus. For gallery visits, holiday dinners and summer parties.
Brushing, Steaming and Hanging a Good Jacket
A blazer that's cared for keeps its shape for years. Most of that care is small and quick.
- Hang wool and tweed on a wide, shaped hanger so the shoulders keep their line. Wire hangers leave bumps.
- Brush wool after wearing to lift dust and lint, then give it a day off before the next wear.
- Steam rather than iron. A steamer relaxes creases without the shine an iron can leave on dark wool.
- Dry clean sparingly. Frequent cleaning wears fabric faster than spot cleaning and airing out.
- Store linen and velvet with space around them; crushing marks velvet and sets deep creases in linen.
Before storing a jacket for the season, empty the pockets and fasten the top button so it hangs straight. A cloth garment bag protects it from dust while letting the wool breathe; plastic covers trap moisture.
Three Blazers Will Cover Most of These Outfits
You don't need thirty blazers. A navy or black single-breasted, a soft neutral in camel or beige, and one in a color or pattern you love will cover nearly every outfit above. Buy for the shoulder, have the sleeves and waist adjusted, and choose fabrics that move with you rather than hold you stiff. Pick one look from this list that matches a plan already in your diary, try it with what's in your wardrobe, and see what's missing before you shop.
