Clients often tell me their autumn closet is all brown, burgundy and black, and they're tired of it by October. Blue is the color I add first. It runs from navy and faded denim to a bright cobalt that cuts through a gray day, and every shade holds up next to wool, suede, corduroy, leather and chunky knits. It also gets along with camel, chocolate, cream, gray and deep berry, so it slots into what you already own. The looks below go from weekend layers to office clothes to one or two bolder pieces, each with shoes, a bag and a coat, and a note on what I'd watch for.

A Blue Coat That Copes With Rain and Wind
Several of these outfits depend on the coat, and in autumn the coat has to deal with weather as well as look good. The fabric matters more than the color here.
- A wool peacoat or overcoat in a dense, felted wool like melton blocks wind well and shrugs off light drizzle. In a downpour it gets heavy and smells of wet wool, so let it dry on a broad hanger away from the radiator.
- A cotton trench in a tightly woven gabardine handles showers and dries quickly, but it isn't warm. Plan on a sweater underneath from mid-autumn.
- A down puffer is the warmest per ounce, but down clumps and loses its warmth when soaked. Synthetic fill keeps working when damp.
- Bright cobalt wool shows salt and road spray more than navy does, so brush it once it's dry.
If you can only buy one blue coat, I'd go for a navy wool coat that ends just above the knee. It covers the most outfits on this list and handles most autumn weather, short of a real downpour.
1. Navy Sweater and Straight-Leg Jeans Outfit

Start here if you want blue without thinking about it. A slightly relaxed navy sweater in wool or cotton should end around the hip; much longer and it shortens the leg over straight jeans. Medium-wash denim gives contrast without breaking the blue palette. Chocolate ankle boots, a matching belt and a structured crossbody add warmth, and gold earrings brighten the dark knit. A light front tuck shows the waist. On colder days, a camel coat over the top is all it needs.
2. Cobalt Coat and Black Trousers Outfit

A cobalt coat is the most useful bright piece I know, because you wear it over neutral clothes and still get all the color. Put it over a clean black turtleneck and tailored black trousers, so nothing competes. Straight, belted or gently oversized all work; I'd check that an oversized one still lets you lift your arms without the hem riding up. Black loafers keep it polished, ankle boots add warmth. A structured black bag, silver jewelry and sunglasses finish it. On a dark, wet commute it's the coat people remember, and it makes you easy to spot in a crowd.
3. Blue Denim-on-Denim Outfit

Double denim works when the two washes are clearly different. Start with an indigo shirt or fitted denim jacket, then straight or wide-leg jeans a shade or two lighter or darker. Matching washes almost exactly is what makes it look like a uniform. A brown suede belt, pointed ankle boots and a roomy tan bag bring in warmth. On colder days, a cream turtleneck goes underneath and a long brown coat on top. Roll the shirt cuffs so the layers stay relaxed. A denim jacket over a denim shirt adds a lot of bulk at the shoulders, so I'd only do that with a thin chambray shirt.
4. Navy Blazer and Gray Trousers Outfit

For work, navy and gray is the softer cousin of black and white. Pair a structured navy blazer with a soft blue button-down and charcoal or heather-gray trousers in whatever cut fits you best. Dark brown loafers and a coordinating tote add warmth, with a slim belt, a gold watch and small studs. For warmth, a fine crewneck can go between shirt and blazer, but only a thin one, or the blazer will strain at the button. The fit I check first is the shoulder seam, which should sit right at the edge of your shoulder.
5. Powder Blue Knit and Brown Skirt Outfit

Chocolate brown is what makes powder blue feel like autumn rather than spring. Choose a fuzzy crewneck or a fine-gauge knit and wear it with a brown suede, corduroy or wool midi skirt. A fitted sweater shows the waist; a looser one can be tucked at the front. Dark brown knee-high boots and a structured top-handle bag continue the brown. Delicate gold suits the soft palette, and a long camel coat or cropped brown jacket goes over it. Fuzzy mohair-style knits shed onto a dark skirt, so a lint roller in the bag earns its place here.
6. Blue Midi Dress and Knee-High Boots Outfit

A long-sleeve blue midi dress is about the least effort outfit for an autumn occasion, as long as the fabric has some weight. Navy, dusty blue and deep cornflower all feel seasonal in ribbed knit, crepe or a heavy jersey; a thin summer fabric in the same color won't. Belt it with a narrow brown belt and add chocolate suede knee-high boots. A camel coat finishes it outdoors, with a medium leather bag and gold hoops or a pendant. If the dress is sleeveless, a fitted turtleneck underneath extends it into colder weeks.
7. Navy Trench Coat and Cream Jeans Outfit

A navy trench over cream is a fresh change from the usual beige trench over navy. Start with a cream ribbed sweater and off-white straight-leg jeans, then the trench on top. Tan loafers or brown ankle boots ground the pale jeans, and a cognac tote links the colors. A printed navy scarf adds warmth at the neck. The adjustable belt lets you change the shape. Off-white jeans show every splash, so I'd keep this one for dry days or roll the jeans to just above the ankle so the hems stay clean.
8. Royal Blue Cardigan and Plaid Skirt Outfit

Royal blue is clear and saturated, so the plaid underneath should pick it up somewhere. Look for a midi or knee-length skirt with brown, navy, cream or muted red, so the whole outfit ties together. Button the cardigan as a top, or layer it over a cream camisole. Brown loafers and socks give it a preppy feel; knee-high boots make it warmer. Add a leather satchel, small hoops and a camel coat. If you're petite, a shorter cardigan keeps the skirt from looking long on you; for more coverage, choose a longer, relaxed cut.
9. Navy Monochrome Knit Set Outfit

Head-to-toe navy is my answer for clients who want the ease of all black but find it harsh. Start with a ribbed turtleneck and a matching knit midi skirt, or a sweater-and-pants set for a more relaxed version. Different textures stop the pieces from blending. Navy suede boots keep the column unbroken; dark brown boots add warmth. A structured navy bag, gold chain and watch finish it, with a long charcoal coat on top. Navy pieces from different makers rarely match exactly, so I look at them together in daylight; under shop lighting, some navies can pass for black.
10. Blue Shirt and Corduroy Pants Outfit

Smooth cotton beside ribbed corduroy is a simple texture pairing that always looks considered. Choose a pale or medium-blue button-down and rust, tobacco or dark brown corduroy pants. Tuck the shirt fully for a neat line, or half-tuck it on the weekend. A navy sweater vest goes over the shirt when it's colder. Brown loafers, a matching belt and a shoulder bag finish it, plus a tan utility jacket outdoors. Corduroy wears shiny at the knees and seat over time, so I'd turn it inside out to wash and skip the dryer.
11. Teal Sweater and Camel Trousers Outfit

Teal is the warmest blue on this list, with enough green in it to sit easily next to camel. Wear a teal turtleneck or crewneck with high-rise camel trousers in wool, twill or brushed cotton. A front tuck defines the waist, or leave a longer sweater out for a relaxed line. Chocolate ankle boots and a matching bag stay in the same warm family, and gold suits the green-blue tone. A cream or dark brown coat goes over it. If bright blues tend to wash you out, teal is often the blue that works.
12. Navy Puffer Jacket and Leggings Outfit

For cold morning walks and a full weekend of errands, a navy puffer over black leggings does the job. Put a long gray or oatmeal sweater between them; it covers the seat and stops the two dark pieces from looking like one block. Chunky white sneakers suit mild weather, black weatherproof boots suit colder, wetter days. A navy cap, compact crossbody and simple scarf finish it. A cropped puffer looks sporty, a longer one is warmer. Down puffers lose their loft in rain, so if you're out in the wet a lot, a synthetic-fill puffer keeps you warmer.
13. Cobalt Sweater and Satin Skirt Outfit

Cobalt and satin make a dressy outfit that still feels relaxed. Choose a satin midi in charcoal, chocolate, muted berry or soft gray, so the skirt calms the bright sweater down. A sweater with a neat ribbed waistband sits naturally above the skirt; a longer one can be tucked loosely at the front. Pointed ankle boots or sleek knee-highs cover the leg. A structured clutch or small shoulder bag and statement earrings finish it, with a tailored black or navy coat on top. It's my pick on this list for a dinner or event where jeans feel too casual.
14. Indigo Jumpsuit and Ankle Boots Outfit

An indigo jumpsuit gives a complete blue outfit in one piece, but fit through the body matters more than with separates. Look for denim, cotton twill or corduroy with a defined waist and a straight or gently wide leg. I always check the torso length by sitting down and lifting your arms; if it pulls at the shoulders or crotch, it's too short for you, and no belt will fix that. Roll the sleeves and add a cognac belt to break up the color. Brown heeled ankle boots lengthen the leg, flat Chelsea boots are more casual. A tan crossbody and layered gold necklaces finish it, with a cream turtleneck and camel coat when it's colder.
15. Blue Peacoat and Wide-Leg Jeans Outfit

A peacoat is short, so it balances wide-leg jeans in a way a long coat can't. Wear it over a cream cable-knit sweater, which brightens the face against the dark wool. High-rise jeans in a medium or deep wash should fall neatly over brown heeled boots, so hem them with the boots on. A plaid scarf brings in navy, camel and burgundy, with a cognac bag and gold earrings. Double-breasted peacoats add width across the chest, so if you're full-busted, wear it open or choose a single-breasted version. A longer peacoat works too, as long as the tailoring is clean.
Double Denim That Doesn't Look Like a Uniform
Denim on denim worries people more than any other look in this post, and it's easier than it seems once you follow a few rules.
- Make the washes clearly different, at least two shades apart. Dark jacket with mid-wash jeans, or a light chambray shirt with indigo jeans.
- Put the darker wash at the bottom if you want the leg to look longer, or at the top if you want to draw the eye up.
- Break the denim somewhere with another texture: a cream knit under the jacket, a suede belt, leather boots.
- Keep the cuts different too. A fitted jacket with wide jeans, or an oversized shirt with straight jeans, looks deliberate. Two boxy pieces together look heavy.
- Skip denim-colored accessories. Brown, tan and cognac leather warm it up.
New raw or dark indigo denim can rub dye onto pale bags and light sofas for the first few weeks, so wash it inside out once in cold water before wearing it with a cream bag.
Blue Fits Into the Closet You Already Have
Navy gives you a dependable base, cobalt brings energy and the paler blues lighten heavy autumn fabrics. For easy pairings, keep camel, cream, gray, chocolate, black and muted berry close by, and mix in denim, suede, corduroy, wool and leather for texture. You don't need a new wardrobe to wear more blue. Pick one favorite blue piece, a sweater, coat, dress or pair of jeans, and build the rest of the outfit from the neutrals you already wear, with shoes and a bag chosen for the weather.
