Dressing a changing body during the final stretch of pregnancy can feel like a daily puzzle, but your third trimester wardrobe doesn't have to be a source of stress. As your bump takes center stage, the right maternity outfit ideas for the third trimester can keep you feeling comfortable, confident, and genuinely like yourself. This is the chapter where breathable fabrics, stretchy waistbands, and bump-accommodating silhouettes become your best friends—whether you're heading to work, running errands, or celebrating at a baby shower. I've pulled together 20 head-to-toe looks that blend function with real-world style, so you can spend less time staring at your closet and more time nesting, resting, and soaking in those final weeks before baby arrives.
1. Maternity Leggings and Oversized Sweater
Is there anything more satisfying than pulling on buttery-soft maternity leggings when your bump feels heavy and nothing else fits quite right? This combo is a third-trimester hero for a reason. Reach for over-the-belly leggings with a supportive panel—they stay put without rolling down. On top, an oversized knit sweater in cream or oatmeal falls loosely over your hips, giving coverage without clinging. Chunky white sneakers keep the look grounded and practical, while a long pendant necklace draws the eye vertically for a lengthening effect. A messy bun and delicate gold hoop earrings finish things off with an effortless, "I woke up like this" energy. Perfect for coffee runs, prenatal appointments, or just lounging in style.
2. Maternity Wrap Dress
A wrap dress might just be the most versatile piece you own during the third trimester. The adjustable tie lets you customize the fit as your body changes week by week, while a V-neckline subtly frames the face. Look for a midi-length style in soft jersey or a ribbed knit with plenty of stretch. Deep jewel tones like emerald or burgundy read polished without trying too hard. Slide into low-block-heel mules or comfortable ballet flats, and add a structured crossbody bag in a complementary neutral. A light swipe of tinted lip balm and simple stud earrings polish the look. This outfit transitions seamlessly from a work meeting to dinner with friends.
3. Maternity Overalls
Overalls during pregnancy feel like a playful throwback with a decidedly grown-up twist. Soft denim or stretchy twill maternity overalls with adjustable side buttons give your belly room to breathe while maintaining a cute, structured silhouette. Pair them with a fitted long-sleeve striped tee underneath—the horizontal lines create a subtle contrast against the vertical straps. White leather sneakers or canvas slip-ons keep the look fresh and casual. Roll the cuffs slightly for an intentional, relaxed vibe. A lightweight canvas tote and a baseball cap add a sporty, weekend-ready feel. This outfit works beautifully for farmers market strolls, casual brunches, or simply tackling your third-trimester to-do list in style.
4. Maternity Jumpsuit
A one-and-done jumpsuit is a gift when bending over to coordinate separates feels like a workout. Look for a stretchy knit or jersey maternity jumpsuit with a smocked bodice or empire waistline that sits above your bump. Wide-leg silhouettes balance proportions beautifully and allow airflow on warmer days. A sleeveless style in olive or black gives you a clean canvas to accessorize. Layer a cropped denim jacket over the shoulders and slip into flat leather sandals or espadrilles. Add a pair of oversized sunglasses, a woven clutch, and a swipe of cream blush for a look that feels effortlessly polished—perfect for a baby shower, a date afternoon, or elevated everyday wear.
5. Maternity Sweater Dress
When temperatures drop, a sweater dress becomes your cold-weather uniform. Choose a ribbed or cable-knit maternity sweater dress that hits just below the knee, with enough stretch to skim your bump without feeling restrictive. A turtleneck style in charcoal grey or camel feels timeless and cozy. Layer it under an open-front longline cardigan for extra warmth and vertical lines that elongate your frame. Pull on opaque maternity tights and knee-high flat boots for a streamlined look. A wool fedora and a structured leather satchel add texture and polish. This outfit works for holiday gatherings, winter baby showers, or any chilly day when you want warmth and style.
6. Maternity Blazer and Pants
You can absolutely bring boss energy to the third trimester without sacrificing comfort. Start with over-the-belly maternity trousers in a stretchy ponte knit—black or navy anchors the look. A soft, long-sleeve fitted tee or lightweight cashmere crewneck tucks smoothly above your bump. The star of the show is an oversized boyfriend blazer, worn open to frame your silhouette without constricting. Pointed-toe flats or low kitten heels keep it office-appropriate while being kind to swollen feet. Layer a delicate chain necklace and grab a structured tote bag to complete the ensemble. This outfit commands the conference room and transitions beautifully to after-work gatherings.
7. Maternity Maxi Dress
Nothing says third-trimester ease quite like a flowing maxi dress. An empire-waist or A-line maxi in breathable cotton, modal, or rayon gives your bump plenty of room while keeping you cool. A floral print or soft watercolor pattern adds visual interest without overwhelming your frame. Pair it with flat strappy sandals or cushioned slide sandals for all-day wearability. A denim jacket tied at the waist or draped over the shoulders adds a casual layer for cooler evenings. A wide-brim straw hat, layered beaded bracelets, and a roomy market tote complete the look. Ideal for warm-weather baby showers, outdoor dinners, or any day you want maximum comfort with minimal effort.
8. Maternity Jeans and Tunic
A great pair of maternity jeans with an over-the-belly panel can restore a sense of normalcy when your pre-pregnancy denim is a distant memory. Choose a slim or straight-leg style in a medium wash. On top, reach for a long tunic in a soft, drapey fabric—think modal or rayon blends that fall to mid-thigh. A tunic with side slits or a curved hem adds movement and prevents the fabric from pulling across your hips. Slip into pointed-toe flats or low-heel booties to elongate the leg line. Add a lightweight scarf, a quilted crossbody bag, and subtle drop earrings. This outfit nails casual-chic for lunch dates, shopping trips, or low-key weekends.
9. Maternity Bodycon Dress
If you want to celebrate your bump rather than hide it, a maternity bodycon dress is your answer. Look for a midi-length ribbed knit dress with ruching along the sides—the gathering detail stretches with you and creates a flattering, contoured silhouette. Solid neutrals like taupe, black, or burgundy work beautifully. Layer a longline utility jacket or cropped moto jacket over top for texture and a bit of edge. White low-top sneakers or flat ankle boots keep the vibe modern and grounded. A sleek low bun, minimalist gold cuff bracelet, and a leather backpack complete the look. This outfit is perfect for maternity photos, casual dinner dates, or whenever you want to feel a little extra.
10. Maternity Linen Pants Outfit
When summer heat and third-trimester swelling collide, linen pants are a breath of fresh air—literally. Choose wide-leg maternity linen pants with a soft, under-the-belly waistband that won't dig or roll. A fitted ribbed tank top in white or cream tucks neatly above the waistband and shows off your bump. The contrast between the structured top and flowy bottom creates a balanced silhouette. Slide into woven leather sandals or espadrille flats for an airy finish. A straw circle bag, delicate anklet, and oversized round sunglasses complete the warm-weather look. Perfect for outdoor brunches, beachside strolls, or any scorching afternoon when you need to stay cool and look put-together.
11. Maternity Cardigan and Dress
A lightweight cardigan thrown over a simple dress creates instant layering magic during the third trimester. Start with a soft cotton or jersey tank dress that skims your curves without clinging. A knee-length or midi style in heathered grey or soft blush serves as the base. Drape a longline open-front cardigan in oatmeal or camel over the top—the vertical lines slim and elongate. Pair with cushioned ballet flats or low-block-heel sandals in a nude tone. A long pendant necklace, dainty stack rings, and a roomy leather tote pull it all together. This outfit transitions easily from a prenatal yoga class to coffee with friends, offering comfort without looking like you've given up on style.
12. Maternity Shirt Dress
A button-down shirt dress brings structure and polish to your third-trimester wardrobe without sacrificing comfort. Look for a relaxed-fit style in lightweight cotton or chambray with a self-tie belt you can position above your bump to create an empire silhouette. Roll the sleeves to three-quarter length for a casual, intentional feel. White sneakers or tan slide sandals keep the look approachable, while a woven belt bag worn crossbody adds a modern, hands-free touch. A simple gold pendant, tortoiseshell sunglasses, and a fresh lip color polish things off. This outfit is a go-to for casual Fridays at the office, weekend errands, or any occasion that calls for looking pulled-together with minimal effort.
13. Maternity Ribbed Knit Dress
Ribbed knit dresses are like a warm hug for your third-trimester body—soft, supportive, and endlessly stretchy. A midi-length sleeveless style in a neutral like charcoal, olive, or sand adapts beautifully as your bump grows. The vertical ribbing creates a lengthening effect, while side slits at the hem allow easy movement. Layer a cropped boxy jacket or a soft shacket on cooler days. White leather sneakers bring a sporty contrast, or swap in flat mules for a dressier take. A minimalist watch, small hoop earrings, and a sleek shoulder bag keep the look clean and modern. Wear it to appointments, casual gatherings, or simply to feel polished while nesting at home.
14. Maternity Two Piece Set
Matching two-piece sets take the guesswork out of getting dressed, which is a win when you're in the third trimester. Look for a coordinated knit lounge set—a relaxed long-sleeve top or crewneck paired with wide-leg pants in soft ribbed jersey. Neutral shades like oatmeal, sage green, or soft black feel elevated and intentional. The pull-on pants with a wide, over-the-belly panel offer comfort without looking sloppy. White platform sneakers and a sleek puffer vest add modern structure. A baseball cap, gold hoop earrings, and a large canvas tote complete the athleisure-inspired look. Ideal for travel days, weekend errands, or anytime you want to look cohesive with zero effort.
15. Maternity Off Shoulder Dress
An off-shoulder dress brings a touch of romance to late pregnancy. Look for a midi or maxi style in soft jersey or smocked cotton with an elasticized neckline that stays put. A solid blush, dusty blue, or classic black keeps the look refined. The off-shoulder cut frames your collarbone and adds visual interest above the bump. Pair with delicate heeled sandals or embellished flats for a dressy finish. A slim clutch, sparkly drop earrings, and a soft wave in your hair elevate the ensemble. This outfit is ideal for a baby shower, maternity photos, or a special dinner. You'll feel feminine, radiant, and perfectly dressed for the occasion.
16. Maternity Biker Shorts and Sweatshirt
For those days when only soft fabrics and zero waistbands will do, maternity biker shorts and an oversized sweatshirt feel like a style win. Choose bike shorts with a supportive over-the-belly panel in black. On top, go for a roomy crewneck sweatshirt in a faded vintage wash or a bold color-block design. The mix of sporty and slouchy reads intentional and on-trend. Chunky crew socks and platform sneakers ground the look with a street-style edge. A nylon belt bag worn crossbody, thick headband, and minimal makeup keep the vibe cool and unfussy. Perfect for casual walks, coffee pickups, or lounging at home while still feeling put-together.
17. Maternity Wide Leg Pants Outfit
Wide-leg pants offer a fashion-forward alternative to leggings when you want a change of silhouette. Choose maternity wide-leg trousers in a flowy crepe or soft woven fabric with an over-the-belly panel or a comfortable under-bump waistband. A fitted scoop-neck tank or short-sleeve knit top balances the volume on the bottom. Tuck the top in slightly above your bump to define the waistline. Slide into flat mules or sleek sneakers depending on the occasion. A structured tote, layered pendant necklaces, and a tailored blazer worn open over the shoulders complete the ensemble. This outfit works for creative offices, brunch dates, or any time you want to look polished and modern.
18. Maternity Denim Jacket Outfit
A classic denim jacket is the ultimate third-trimester layering piece—it adds structure without restricting your bump. Start with a soft floral midi dress or a solid tank dress in a stretchy jersey fabric. Layer an oversized light-wash denim jacket over the top, worn open to frame your bump casually. White canvas sneakers or tan leather slides anchor the look, depending on the season. Add a canvas tote bag, a silk scarf tied around the handle, and tortoiseshell hoop earrings for a touch of personality. This laid-back outfit works beautifully for transitional weather, weekend outings, or anytime you want an easy, breezy layer that ties the whole look together.
19. Maternity Tunic and Leggings
When you want the comfort of leggings but a slightly more polished look, a long tunic is your best friend. Choose cotton maternity leggings with full belly coverage. On top, a printed or solid tunic in a fluid fabric that falls to mid-thigh elongates your silhouette. Look for details like a gentle V-neck or subtle embroidery that elevate the look above basic loungewear. Slip into comfortable ballet flats or cushioned loafers. A long pendant necklace, a cozy wrap scarf, and a leather crossbody bag add polish. This outfit is ideal for casual Fridays, travel days, or any occasion where you want to feel pulled-together while prioritizing comfort above all else.
20. Maternity Babydoll Dress
A babydoll dress brings an effortless feminine feel to third-trimester dressing. With its empire waistline sitting just below the bust, the silhouette floats away from the body, giving your bump plenty of room without any tightness. Look for a floral print or soft solid hue in lightweight cotton or rayon. Short puff sleeves or delicate ruffled cap sleeves add charm. Pair with flat sandals or simple white sneakers for an easy daytime look. A woven crossbody bag, dainty layered necklaces, and a swipe of cream blush complete the ensemble. Wear this to a casual baby shower, a picnic in the park, or any sunny afternoon when you want to feel pretty and comfortable at the same time.
