Overalls might be the most honest maternity garment there is. Nothing presses on your waist, the straps lengthen as the bump grows, and fall gives you everything they pair well with: soft layers, sturdy shoes and deep, warm colors. I look for adjustable straps, side buttons or panels, a roomy leg and a fabric that's comfortable sitting down as well as walking. A fitted top underneath keeps the shape neat, and an open cardigan, shacket or coat adds warmth without squeezing anything. Sneakers, loafers, clogs and low boots keep you steady. Treat the fifteen outfits below as formulas, then adjust the layers for your weather and your stage of pregnancy.
Regular Overalls in a Bigger Size, or a Maternity Pair?
People often ask whether they can just size up in ordinary overalls. Sometimes, yes. A relaxed pair with long adjustable straps and side buttons can work through the middle of pregnancy. The problem shows up later: the bump needs extra length in the front, not just width. Regular overalls pull the bib down and the crotch forward, so the legs start to twist and the back rides up.
Maternity overalls add room in front, usually with a deeper bib, stretch side panels or a cut that drops lower at the front waist. Here's what I check in either kind before I'd recommend them:
- Strap range. Let the straps out to the last setting. You want several inches to spare, because they'll need it later.
- Side openings. Buttons or zips at the hips make getting in and out much easier once bending over is uncomfortable.
- The seat and rise. Sit, squat and climb a step. If the back seam pulls tight now, it will only get worse.
- Fabric stretch. A little stretch in denim adds comfort. A lot of stretch tends to bag at the knees and seat by lunchtime.
1. Denim Maternity Overalls With Long-Sleeve Tee
Blue denim overalls over a fitted long-sleeve tee is the simplest version, and the one I'd buy first. The tee should be slim enough to lie flat under the bib; anything loose bunches into ridges behind it. White, gray or black all work. Adjustable straps and stretchy side panels let one pair carry you from the second trimester well into the third. White sneakers keep it fresh for errands and appointments. When it cools off, add a light camel cardigan left open. If the legs are long, roll them once. A thick double cuff adds weight at the ankle and makes the whole outfit look heavier.
2. Black Maternity Overalls With Striped Turtleneck
A striped turtleneck turns black overalls graphic and sharp. Choose a light, stretchy knit with an easy neck, shoulders and body, because a tight turtleneck under a bib can feel confining when you're already warm. Black-and-white stripes are the classic; cream-and-tan softens it. Low black ankle boots with a stable sole and roomy toe box ground the dark denim, and a camel tote adds contrast for a casual office or lunch. Over the top, a long wool-blend coat worn open. Keep jewelry to studs or a fine chain. Stripes are already busy, and they're the point of this outfit.
3. Corduroy Maternity Overalls With Cream Sweater
Corduroy is the warmest overall fabric here, and the texture does a lot of the styling for you. Rust, camel, chocolate or olive in a relaxed leg with adjustable side openings. Underneath, I'd choose a fine, close-fitting cream knit over a chunky one, since the overalls already carry volume and two bulky layers make you look bigger than you are. Suede clogs or low-heeled brown ankle boots match the warmth. A pendant and compact shoulder bag are enough. One care note: wash cord inside out on a gentle cycle, or the wale flattens and goes shiny at the knees.
4. Olive Maternity Overalls With Plaid Shacket
Olive is my favorite alternative to blue denim, because it already sits with every autumn color. Start with a fitted white maternity tee, then add an oversized plaid shacket in cream, brown, rust or muted green, worn open. The open front shows the bib and bump and draws one long line down the middle. Neutral slip-on sneakers with ribbed socks keep it easy on busy days. A tan crossbody and quiet gold jewelry finish it. If the shacket feels heavy over the bib, push up the sleeves or choose brushed cotton instead of thick wool. Wool shackets plus overalls can get hot fast.
5. Wide-Leg Maternity Overalls With Fitted Turtleneck
Wide-leg overalls look surprisingly grown-up with a sleek top. Dark indigo, charcoal or black, paired with a fitted cream turtleneck in stretch jersey. The slim top shows your arms and shoulders, so the volume of the wide leg reads as intentional rather than shapeless. Leather loafers with cushioned insoles keep it daytime-smart. Hem length is the make-or-break detail: a wide leg that drags the floor gets wet, dirty and stepped on, and you can't easily see your feet late in pregnancy. Have it shortened rather than cuffed. A top-handle bag, gold hoops and an open trench take it to work.
6. Maternity Overall Dress With Sweater And Boots
An overall dress gives you the bib and straps with far more room through the hips and legs. Choose a knee-length denim or corduroy version over a fitted ribbed sweater in oatmeal, burgundy or forest green. Opaque maternity tights cover you on cool days, with flat knee boots or supportive ankle boots. Before you buy, sit down and bend in it; as the bump grows, it lifts the front hem, so a dress that's knee length now can sit noticeably shorter in front by the third trimester. A cropped jacket balances the shorter shape better than a long cardigan. Add a scarf if needed for work, lunches or photos.
7. Dark Wash Maternity Overalls With Chambray Shirt
Double denim works when the two blues are clearly different. Dark wash overalls over a lighter chambray button-down, top buttons open over a maternity tank, sleeves rolled. If both washes are close, it looks like an accident instead of a choice. Brown Chelsea boots break up the blue and handle cool weather, with a cognac crossbody and a slim watch. Mix textures too: a soft, slightly faded chambray against crisp indigo. The shirt should fit through the shoulders and arms, while the overalls need room through the bump, hips and seat. That seat room is easy to forget, and it goes first.
8. Distressed Maternity Overalls With Hoodie And Sneakers
Some days you just want a hoodie, and this makes it look deliberate. Lightly distressed overalls over a slim cotton hoodie. Skip hoodies with a big front pocket, which bunches into a lump right under the bib. Heather gray, navy or muted burgundy all sit well with medium-wash denim. High-top sneakers and crew socks give it a sporty edge, and a nylon crossbody stays light. Add an oversized utility jacket if you need more warmth. Keep any distressing away from the knees; ripped knees let cold air in and tend to tear further every time you kneel or crouch.
9. Brown Maternity Overalls With Black Mock-Neck Top
Chocolate brown overalls with a black mock-neck look more polished than any blue denim pair. Soft cotton twill or fine corduroy with adjustable straps and a straight or slightly tapered leg. A fitted black mock-neck keeps the top half sleek and gives strong contrast. Black lace-up boots with a low heel and flexible sole hold your foot securely, though lacing gets harder to reach later on, so a side zip is worth looking for. A black shoulder bag ties the accessories together, and small gold earrings warm the dark palette. On chilly afternoons, add a camel coat or long neutral cardigan.
10. Light Wash Maternity Overalls With Long Cardigan
Light wash overalls and a long cardigan is the softest look here. Start with a fitted white or taupe tank or long-sleeve tee, depending on the temperature. A knee-length cardigan in oatmeal, soft gray, dusty blue or muted rose goes on top, open so it falls in two vertical lines beside the bump. Supportive ballet flats or low sneakers work indoors and out. Avoid belted cardigans; a tie wrapped across the bib presses on the bump and adds a lump of fabric where you least want one. It takes you from a cool morning to a warm afternoon on coffee runs and visits.
11. Maternity Overalls With Flannel Shirt And Hiking Boots
For pumpkin patches and trail walks, sturdy overalls with an open flannel and hiking-style boots are my go-to. A fitted black or cream tee underneath, the flannel unbuttoned as a light jacket in rust, navy, forest green or tan plaid. Traction matters most in the boot: wet leaves and muddy rows are slippery, and your balance changes as the bump grows. Choose a low-profile boot with room for thick socks. A quilted vest adds core warmth without closing over the bump, and a belt bag across the chest leaves both hands free. Every layer comes off easily as the day warms.
12. Black Maternity Overalls With Button-Down Shirt
Black overalls can pass in a creative or casual office if everything else is crisp. Layer them over a white or pale blue button-down in soft cotton or a fluid wrinkle-resistant fabric, untucked under the bib with the cuffs rolled neatly. Pointed flats or supportive leather mules, whichever feels steadier. A structured tote, small earrings and a simple watch keep it professional. The overalls themselves need to look clean: minimal hardware, tidy seams, a straight leg, no distressing. If the office runs cold, a longline blazer worn open frames the outfit without pressing on the bump.
13. Maternity Overalls With Trench Coat And Sneakers
A trench is the right coat for overalls in changeable fall weather. Dark wash denim overalls, a fitted camel, cream or black knit, and a water-resistant trench in a relaxed cut, worn open or with the belt tied loosely behind your back. That back-tie trick keeps the belt from dangling without cinching anything over the bump. White sneakers brighten the dark denim for long walks. A tan or burgundy crossbody and a light scarf finish it. Aim for a trench that ends around the knee; a longer one can swamp a shorter frame. It handles commuting, city errands and travel days.
14. Rust Maternity Overalls With Graphic Tee And Denim Jacket
Rust overalls bring plenty of color by themselves, so keep the rest quiet. A cream maternity tee with a small graphic, and a medium-wash denim jacket in a relaxed fit you can leave open. Push the jacket sleeves up so the tee shows and the layers feel lighter. Low neutral sneakers and a canvas tote keep it weekend casual. With a wide-leg pair, choose slimmer shoes; chunky sneakers plus a wide hem make the lower half look heavy. It's a cheerful outfit for school pickup, shopping and casual outings, with nothing fussy to manage.
15. Cream Maternity Overalls With Burgundy Sweater
Cream overalls with deep burgundy are the pairing I'd choose for fall photos. Choose soft denim or cotton twill with a roomy straight leg and hardware that adjusts easily. A fine burgundy knit underneath should lie smoothly across the shoulders and arms. The light bib against the dark sweater outlines the bump clearly on camera. Brown suede ankle boots add texture, and a felt hat suits outdoor pictures if you like wearing one. Fair warning: cream shows every grass stain and smudge, so keep it for the photo day rather than the orchard. A small tan bag and fine gold jewelry finish it for showers and family pictures.
The Bathroom Question, and Other Overall Logistics
The honest downside of overalls is that frequent bathroom trips, which come with pregnancy, mean undoing straps every time. A few choices make that much easier. Clip or button straps unfasten faster than tied ones. Side buttons let the whole bib drop without wrestling. Avoid long straps that can trail on the floor when you unclip them; tuck them into the front pocket or knot the extra length.
- Under a coat: metal buckles at the shoulder can press under a heavy bag strap or a fitted coat. Carry a crossbody on the opposite side and choose roomier outerwear.
- Warmth: the bib covers your chest, so the layer underneath can be thinner than you think. A fitted long-sleeve top is often enough under a jacket.
- Washing: fasten the buckles before machine washing so they don't bang around or snag other clothes, and air dry stretch denim to help it keep its shape.
Many of these pairs stay useful after birth too. The adjustable fit suits the months when your body is still changing, and the bib hides a postpartum waist without any squeezing.
Overalls Earn Their Place by the Third Trimester
Overalls keep working long after most maternity pants have stopped, because nothing about them depends on your waist. Start with one comfortable pair, a few soft fitted tops and shoes that feel secure all day, then rotate layers. Classic denim with sneakers and corduroy with boots cover most of fall, and open outerwear keeps you warm without pressure on the bump. When you shop, look for adjustable straps, side buttons or panels, useful pockets and a hem that clears the ground. Get those right, and getting dressed through the season becomes the easy part of your day.
