Late August into September is the stretch where I see people give up and just wear whatever's clean. The mornings are cool, the afternoons are still hot, and the office air conditioning is colder than either. You don't need a new wardrobe for it. Keep your breathable summer pieces and add a light jacket, a cardigan or a blazer you can take off. Then shift the colors a shade deeper and swap the sandals for closed shoes once the evenings bite. The twenty outfits below each pair one summer piece with one early-fall piece, and every look is written out down to the shoes.
Summer Pieces Worth Keeping Out Until October
When I help someone switch over their closet in late summer, we don't pack everything away. We sort. Some warm-weather pieces carry into fall with a small change, and some really are done for the year.
Keep These in Rotation
- Tanks and plain tees, which become the base layer under cardigans, blazers and jackets
- Slip dresses and midi skirts, which take a knit on top and boots below
- White or ecru jeans, worn with brown leather and darker tops
- Linen trousers in dark or earthy colors, which look seasonal long after pale linen stops
Put These Away First
- Very bright or neon colors, which look out of step once the light softens
- Flimsy flip-flops and beach sandals
- Short, frayed denim cutoffs, unless you're somewhere that's still hot
- Sheer pieces with nothing to layer under them
The color shift does more than any single purchase. A cream tank under a rust cardigan says fall. The same tank under a lime one still says July.
1. White Tank And Wide Leg Jeans Summer Fall Outfit
A fitted white tank with wide-leg jeans is the base I'd build half of September on. Go for lighter-weight denim with a high or mid rise so you get structure without heat. The striped button-down worn open over it is the layer that comes off at lunch. Brown leather sandals keep it summery, and a matching brown belt and structured shoulder bag nudge it toward fall. Small gold hoops and sunglasses finish it. When the weather turns, loafers or low sneakers take the sandals' place. Petite women often do better with a cropped wide leg; taller women can let the hem pool slightly.
2. Slip Dress And Denim Jacket Summer Fall Outfit
A slip dress under a denim jacket is soft against stiff, and that contrast is why it works. Choose a midi in olive or chocolate, or a muted floral, and a slightly relaxed denim jacket with the sleeves pushed up. White sneakers suit the day; ankle boots take it later into fall. A crossbody bag and a simple pendant finish it. Slip dresses cut on the bias skim the body rather than cling, which matters if you'd rather not show every line. The jacket gives you coverage at the arms and shoulders and is easy to take off, so the dress still does its job.
3. Linen Vest And Straight Jeans Summer Fall Outfit
A tailored linen vest looks sharper than a tee and stays cooler than a blazer. Wear it buttoned on its own as a top, or over a fitted cotton tee if you want more coverage at the arms. Cream, tan and muted brown carry from August to October. Pair it with straight-leg jeans and sleek loafers or woven flats. A structured tote makes it work for a casual office, and a smaller bag shifts it to the weekend. Check the armholes before buying. Vests cut tight there pull at the bust and gape when you lift your arms, so size up rather than settle.
4. Midi Skirt And Lightweight Sweater Summer Fall Outfit
The first breezy, dry day of the season is when I pull this one out. A flowing midi skirt keeps the summer feel, and a fine-gauge crewneck adds warmth without bulk. Cream over a rust or printed skirt gives a gentle contrast. A small front tuck shapes the waist; left loose, it's more relaxed. Ballet flats suit warm days, and suede ankle boots take over once it cools, though keep the suede away from a wet forecast. A medium shoulder bag and quiet jewelry finish it. It's an easy one to take from the office to dinner.
5. T-Shirt Dress And Utility Jacket Summer Fall Outfit
A T-shirt dress is about the most comfortable thing you can wear in heat, and it needs a jacket to look like you meant it. Choose a knee-length or midi version in charcoal or muted green, then add an olive or tan utility jacket with the sleeves rolled. White sneakers, a crossbody and a cap make it an errands outfit; loafers and a structured bag smarten it. Belt it or wear it loose. My one test is the fabric weight. A thin, clingy jersey shows everything underneath, so look for a heavier cotton jersey that holds its own shape.
6. Button-Down Shirt And Tailored Shorts Summer Fall Outfit
Tailored shorts can stay in rotation well past August if you treat them like trousers. Pick a longer pair with a proper waistband and a relaxed leg, then tuck in a lightweight blue or striped cotton shirt with a slim leather belt. Loafers push it toward fall; minimal sandals keep it in summer. A structured tote and a light cardigan around the shoulders handle cold offices. Camel, navy and chocolate shorts feel more seasonal than bright colors. Where the hem lands matters most. Just above the knee looks deliberate; much shorter starts to read as the beach.
7. Floral Dress And Suede Boots Summer Fall Outfit
Most floral dresses can make the switch to fall if the print has some depth in it. Look for plum, forest green or rust in the pattern, not just pastels. Tan or chocolate suede boots replace sandals and give the soft dress visual weight. A cropped cardigan adds warmth and keeps the waist visible, or a fitted denim jacket gives more structure. Finish with a leather crossbody, small hoops and a narrow belt if the shape allows. Breathable fabric and sleeves you can push up handle a warm afternoon. You don't need thick tights or a heavy coat yet.
8. Graphic Tee And Satin Skirt Summer Fall Outfit
A graphic tee tucked into a satin skirt keeps the skirt from feeling like evening wear. Choose a soft, slightly oversized tee and a midi skirt in olive or deep burgundy. Retro sneakers keep it daytime; loafers sharpen it. A cropped denim jacket handles the cooler hour after sunset. Keep accessories small, like a shoulder bag, sunglasses and a short necklace. Thin shiny satin catches the light on every curve, so if that bothers you, look for heavier satin with a matte finish. It drapes more and wrinkles less. I'd wear this to a museum or a casual lunch.
9. Blazer And Denim Shorts Summer Fall Outfit
Denim shorts and a blazer is my answer for climates where fall takes its time. Start with high-rise shorts in a medium or dark wash and a fitted tank or crewneck tee, then add a linen-blend blazer in tan or soft gray. The blazer gives structure; the shorts keep you cool. Leather loafers, refined sandals or minimal sneakers all suit it, with a belt and structured bag tying the two moods together. Linen blends crease, and that's fine here, since a slightly rumpled linen blazer looks relaxed rather than messy. For a workplace version, choose longer shorts.
10. Knit Polo And White Jeans Summer Fall Outfit
A short-sleeve knit polo has more texture than a tee and still breathes in late-summer heat. Pair one in camel or burgundy with straight white jeans. The brown loafers and matching belt are what shift the white denim toward fall, while a woven tote keeps a hint of summer. A slim watch, gold earrings and sunglasses finish it. On a cool morning, throw a trench or denim jacket over the top. If bright white jeans feel stark on you, ecru or off-white is easier to wear and doesn't show every speck of dust. It's a smarter alternative to a plain tee and jeans.
11. Cardigan And Denim Midi Skirt Summer Fall Outfit
A denim midi skirt gives you leg coverage for cooler mornings and still lets air in at the hem when it warms up. Wear it with a fitted cotton tank and a lightweight cardigan in cream or rust. Button the cardigan as a top on cool days and wear it open in the afternoon. Ballet flats look soft; loafers or low ankle boots look sturdier. A compact shoulder bag and fine jewelry finish it. Denim midis are stiff, so a front slit matters for walking. I'd also choose a cardigan that stops at the waistband rather than at the widest point of the hips.
12. Striped Shirt And Linen Pants Summer Fall Outfit
A striped button-down with relaxed linen pants is about as breathable as covered-up dressing gets. Choose cream or chocolate trousers and a blue-and-white striped shirt. Half-tuck it, wear it open over a tank or knot it at the waist. Leather slides suit the heat; loafers take the same outfit into cooler days. A woven leather bag, simple earrings and a thin sweater over the shoulders finish it. Linen wrinkles by noon, and I'd accept that rather than fight it. Changing the trouser rise and shirt length adapts it to petite, tall or curvy figures, and it packs well for travel.
13. Jumpsuit And Cropped Jacket Summer Fall Outfit
A sleeveless jumpsuit is a whole outfit in one step, and a cropped jacket makes it work when the weather shifts. Look for a utility, denim or wide-leg jumpsuit in olive or warm brown, then add a cream twill or denim jacket that ends at the natural waist. That short jacket keeps the one-piece from looking bulky and shows your shape. Sneakers suit long days, loafers sharpen it, and ankle boots carry it into fall. Add a structured crossbody and mid-size hoops. Jumpsuits are hard to fit through the torso, so an adjustable waist with a removable belt saves a lot of frustration.
14. Crochet Top And Cargo Pants Summer Fall Outfit
Crochet keeps a summer texture going, and cargo pants pull it into early fall. Layer a lined or tightly worked crochet top over a camisole, then add olive or khaki cargo pants with a relaxed straight leg. Low sneakers, fisherman sandals or leather clogs all work depending on the weather, with a canvas shoulder bag and, if needed, a cropped utility jacket. Keep to cream, tan, brown and muted green. Open crochet snags easily on bag zips and jewelry, so wear it with simple accessories. If loose cargos swamp your frame, choose a slimmer pair with flat pockets and a higher rise.
15. Sweater Vest And Poplin Shirt Summer Fall Outfit
Crisp mornings with mild afternoons are when a sweater vest over a poplin shirt makes sense. Start with an oversized white or pale blue button-down and add a lightweight vest in camel or navy. Pair them with straight-leg jeans or cropped tailored trousers, then loafers for polish or white sneakers for weekends. A structured tote and small studs keep it clean. Leave the shirt tail out for relaxed coverage, or tuck both layers into high-rise pants for definition. A V-neck vest lengthens the upper body and sits better over a fuller bust than a crew neck does.
16. Tank Dress And Oversized Blazer Summer Fall Outfit
A fitted tank dress turns into something you can wear to an office with an oversized blazer on top. Choose a midi in black or dark olive, then a breathable linen-blend or lightweight wool blazer with the sleeves pushed up. Minimal sneakers keep it daytime, while slingback flats or ankle boots sharpen it. A structured bag, quiet earrings and a watch finish it. If you'd rather not show your shape, pick a straight tank dress and wear the blazer open for a long vertical line. When the room heats up, the blazer comes off and you're still dressed.
17. Chambray Shirt And Black Trousers Summer Fall Outfit
Chambray is a summer cloth, but tucked into black trousers it looks ready for work. Choose a lightweight, relaxed shirt and tuck it into high-rise straight or wide trousers. Roll the sleeves neatly to the forearm so it doesn't look too formal. Black loafers keep it streamlined; white sneakers relax it. A belt, a roomy tote and simple metal jewelry finish it, and a tan trench handles cooler days. Curvy figures often find front-pleated trousers with some give at the waist more comfortable, and petite women can go cropped. Chambray softens with every wash, so it gets better over the season.
18. Ribbed Top And Printed Maxi Skirt Summer Fall Outfit
A printed maxi skirt carries a lot of movement and volume, so the top needs to be neat. A fitted ribbed tee or tank in one color pulled from the print ties it together. Rust, navy and plum prints read fall without feeling heavy. Flat ankle boots, ballet flats or clean sneakers all suit, with a cropped denim jacket for warmth and a crossbody bag. Maxi skirts catch on stairs and car doors, so I check that the hem clears the floor in flats. A very full skirt needs a close top; a straighter one can take a looser knit.
19. Bermuda Shorts And Lightweight Trench Summer Fall Outfit
Bermuda shorts sit between summer bare legs and full-length fall trousers. Choose a tailored pair in camel, black or a quiet plaid, then a fitted tee or sleeveless knit. A lightweight trench over the top handles cool mornings and windy evenings. Loafers, slingbacks or slim sneakers keep it walkable, with a leather belt and structured bag. The fit I look for: a hem near the knee that doesn't grip the thigh when you sit. A high rise defines the waist under a long coat. It's ideal where early fall stays mild.
20. Monochrome Brown Summer Fall Outfit
Brown from head to toe reads autumn even in light summer fabrics, which is why it works this time of year. Start with a chocolate tank and pair it with camel wide-leg trousers, a tan midi skirt or brown linen pants. A lightweight cardigan in a neighboring shade adds depth. Cream sneakers, dark brown loafers or cognac sandals complete it, with a bag in a slightly different brown and simple gold jewelry. Mix cotton, linen, leather and fine knit, or the tones go flat. The same idea moves easily between work, travel and weekends.
Sandals, Loafers or Boots on an In-Between Day
Shoes are where most transitional outfits go wrong, because feet feel the temperature change before the rest of you. I decide by the coldest part of the day I'll be outside, not by the afternoon high.
If the morning is mild and dry, sandals still work, especially leather slides or fisherman styles that look a little more covered. Once mornings feel cool, loafers are the bridge. They're closed, they go with bare ankles, and they suit almost every outfit in this list. When the forecast mentions rain or temperatures that need tights, it's time for ankle boots.
Two practical notes. Bare feet in loafers can rub at the heel, so no-show socks save your skin for the first few weeks. And new ankle boots should be worn around the house a few evenings before a long walking day, since stiff leather at the ankle crease is what usually causes blisters.
Suede looks right for early fall but marks easily in rain. Treat it with a protector spray before the first wear, and keep a smooth leather pair for wet days.
Two Seasons in One Closet for a Few Weeks
The trick to these weeks is mixing the two seasons instead of switching all at once. Keep your breathable summer basics and add lighter jackets, cardigans, blazers, deeper colors and sturdier shoes as the weather earns them. Those small swaps handle cool mornings, warm afternoons and cold offices. Treat each outfit here as a formula you can change: a different hem, shoe, color or layer to suit your climate, shape and workplace. If it feels familiar and comfortable but still looks like the new season, you've got it right.
