Quick take: If you’re looking for one sundress that does it all, the FOMELY cotton dress is the clear winner.
It was a sweltering July afternoon, 34 weeks pregnant with my second, and I was standing in the middle of John Lewis, sweating through yet another ill-fitting ‘maternity’ dress that promised ‘all-day comfort’ but delivered a waistband digging into my ribs. That’s when I realised: most sundresses aren’t designed for real bodies—especially not for the ones growing, shifting, and overheating through pregnancy. What I needed wasn’t just a pretty dress; it was something that could handle a 3am snack run, a toddler’s sticky hands, and still look put-together for a last-minute GP appointment. So I set out to test sundresses that actually work for mums: breathable fabrics that don’t cling, forgiving cuts that grow with you, and details like pockets for snacks or a phone. I wore each one through heatwaves, hospital visits, and park picnics, judging them on four things: comfort (would it survive a full day?), versatility (could I dress it up or down?), durability (would it hold up after 10 washes?), and whether it flattered a changing body without feeling like a ‘maternity’ label. Here’s what I found—no hype, just real wear from someone who’s been there.

Quick comparison
1. FOMELY Womens Square Neck Cotton Sundress Casual Summer Mini Dress Whi… — The everyday cotton hero
I bought the FOMELY sundress in white at 28 weeks, thinking it’d be a one-season throwaway. Turns out, it became my most-worn dress of the summer. The cotton is thick enough to not be see-through but light enough to not trap heat—critical when you’re already running a degree warmer. The square neckline is flattering without being fussy, and the relaxed fit meant it still worked at 38 weeks, though I sized up from my pre-pregnancy norm. I wore it to a friend’s wedding with sandals and a denim jacket, then to the park the next day with trainers and a cardigan. The only downside? It wrinkles like mad if you sit in it for too long, so it’s not ideal for travel. But for everyday wear, it’s a winner. It’s held up well after 15 washes, though the lace trim has started to fray slightly at the edges. If you want one dress that does it all, this is it.
- Breathable 100% cotton that doesn’t cling
- Square neckline flatters a growing bump or postpartum tummy
- Easy to dress up or down
- Holds up well in the wash
- Wrinkles easily if you’re not careful
- Lace trim frays after repeated washing
- White shows stains (not ideal with toddlers)
Not ideal for: Those who hate ironing
2. WIHOLL Casual Dresses for Women Sleeveless Scoop Neck Flowy Spring Mid… — The flattering midi with pockets
I’ll admit, I was sceptical of the ‘tummy control’ claim on the WIHOLL midi dress, but it actually delivers. The high empire waist cinches just under the bust, which is perfect for hiding a postpartum pooch or a third-trimester bump. The fabric is a polyester-rayon blend, so it’s not as breathable as cotton, but it’s stretchy and forgiving. I wore it to a baby shower with wedges and felt put-together, then to the playground the next day with flip-flops. The pockets are a game-changer—I stashed my phone, a snack, and even a small toy in there. The floral print is cheerful without being overwhelming, and the midi length works for most heights. It’s not perfect: the fabric pills slightly after washing, and the scoop neck can gape if you’re busty. But for the price, it’s a steal. I’ve already bought a second one in a different print.
- High waist flatters a bump or postpartum tummy
- Pockets for practicality
- Versatile for day or night
- Affordable price point
- Polyester blend isn’t as breathable as cotton
- Scoop neck can gape on larger busts
- Fabric pills after repeated washing
Not ideal for: Those who overheat easily
3. elescat Summer Dresses for Women Sleeveless Sundresses… — The budget-friendly throw-on
The elescat sundress is the kind of dress you buy in three colours because it’s so cheap. It’s not fancy—just a simple, loose-fit dress with pockets and a swing hem. I wore it to the supermarket, the park, and even to a casual lunch with friends. The fabric is thin and breathable, but it’s also slightly see-through, so I always wore a slip underneath. The pockets are shallow but handy for keys or a dummy. It’s not a dress you’d wear to a wedding or anything formal, but for everyday wear, it’s comfortable and effortless. The downside? It wrinkles easily, and the fabric feels a bit cheap—it’s not something that will last years. But for £10, it’s a great throw-on option for hot days or when you can’t be bothered to think about what to wear.
- Super affordable
- Pockets for convenience
- Lightweight and breathable
- Easy to throw on
- Thin fabric is slightly see-through
- Wrinkles easily
- Not durable for long-term wear
Not ideal for: Formal occasions or longevity
4. WIHOLL Summer Dresses for Women 2026 Elegant Classy A Line Sleeveless… — The breezy floral mini
The WIHOLL mini sundress is the kind of dress that makes you feel put-together without trying. The floral print is cheerful, and the A-line cut is flattering on most body types. I wore it to a friend’s garden party and got so many compliments—it’s dressy enough for an event but still comfortable. The fabric is a polyester-spandex blend, so it’s stretchy and forgiving, but it’s not as breathable as cotton. The scoop neckline is flattering, though it can gape if you’re busty. The pockets are a nice touch, but they’re more for show than function—they’re too small to hold much. It’s a great dress for summer outings, but it’s not something I’d wear to the park with a toddler—it’s too nice to risk stains. It’s held up well after washing, though the print has started to fade slightly. For the price, it’s a solid choice if you want something cute and versatile.
- Flattering A-line cut
- Cheerful floral print
- Stretchy and comfortable
- Affordable price
- Polyester blend isn’t very breathable
- Pockets are too small to be useful
- Print fades after washing
Not ideal for: Everyday wear with kids
5. ZABERRY Sundresses for Women 2026 Spring Summer Dresses Womens Milkmai… — The postpartum confidence booster
I bought the ZABERRY milkmaid dress at 36 weeks, thinking it’d be a nice option for postpartum. Turns out, it became my go-to for those first few months after birth. The square neckline and ruffle hem add a little polish, while the adjustable straps mean you can tweak the fit as your body changes. The fabric is soft and stretchy, so it’s comfortable even when you’re still figuring out your new shape. I wore it to my six-week check-up and felt like a human again—not just a mum in pyjamas. It’s dressy enough for a baby shower or a date night, but still casual enough for a coffee run. The only downside? The ruffles can be a bit fussy if you’re not into that style. It’s also on the pricier side, but I think it’s worth it for the confidence boost. It’s held up well after washing, though the straps have stretched slightly over time.
- Flattering for postpartum bodies
- Adjustable straps for a custom fit
- Soft, stretchy fabric
- Dressy enough for events
- Ruffles may not be everyone’s style
- Straps stretch over time
- Higher price point
Not ideal for: Those who prefer minimalist styles
6. Summer Dresses for Women 2026 Trendy Casual Sundresses with Pockets Te… — The coolest option for heatwaves
The BKRIVE eyelet sundress is the dress I reached for during the hottest days of summer. The perforated fabric lets air through, so it’s actually cool to wear—something I didn’t think was possible in a dress. The loose fit means no clinging, and the pockets are deep enough to hold my phone and keys. I wore it to a beach day with my toddler, and it was perfect—lightweight, breathable, and easy to move in. The only downside? The eyelet fabric can snag on jewellery or bags, so you have to be careful. It’s also not the most formal option—it’s more of a casual, everyday dress. But for hot weather, it’s a lifesaver. It’s held up well after washing, though the floral print has started to fade slightly. For the price, it’s a great option if you need something cool and comfortable.
- Perforated fabric is actually cool
- Loose fit doesn’t cling
- Deep pockets for practicality
- Affordable price
- Eyelet fabric can snag
- Not dressy enough for formal occasions
- Print fades after washing
Not ideal for: Formal events or durability
How to choose
What to look for
When you’re pregnant or postpartum, your body changes fast, so the right sundress needs to do more than just look pretty. First, prioritise fabric: cotton and rayon blends are breathable and gentle on sensitive skin, while polyester can trap heat—something you’ll want to avoid when you’re already overheating. Look for stretchy or forgiving cuts, like A-line or empire waists, which grow with you and flatter a bump or a softer tummy. Details like pockets are a lifesaver for stashing snacks, a phone, or a dummy, and adjustable straps can help accommodate a changing bust. Length matters too—midi and maxi dresses are versatile, while minis can feel too short as your bump grows. Finally, think about versatility: can you dress it up with jewellery or down with trainers? The best sundresses work for a park picnic, a GP appointment, or a last-minute dinner out. If you’re postpartum, look for styles that cinch at the smallest part of your waist to create a flattering silhouette, and avoid anything too clingy if you’re not ready for that yet.
Common mistakes to avoid
One of the biggest mistakes I see mums make is buying a dress that only fits their current size. Your body changes rapidly during pregnancy and postpartum, so a dress that fits at 20 weeks might not work at 30 weeks—or vice versa. Always size up if you’re unsure, and look for styles with stretch or adjustable features. Another mistake is ignoring the fabric: a dress that looks great in photos might be unbearable in real life if it’s not breathable. Polyester blends can be hot and clingy, while cotton is cooler but can wrinkle easily. Don’t forget to check the care instructions either—some dresses need hand-washing or delicate cycles, which isn’t practical with a newborn. Finally, avoid dresses that are too fussy or formal for everyday wear. You want something you can throw on without thinking, not a dress that requires ironing, special shoes, or a full face of makeup. And if you’re postpartum, steer clear of anything with a tight waistband—it’s not worth the discomfort.
Budget vs premium — is more expensive worth it?
The short answer? Sometimes, but not always. Premium sundresses often use higher-quality fabrics, like organic cotton or rayon blends, which are softer, more breathable, and last longer. They might also have better construction—think reinforced seams, deeper pockets, or adjustable straps. But that doesn’t mean you can’t find a great dress on a budget. The WIHOLL midi dress, for example, is under £20 and ticks all the boxes for comfort and versatility. The key is to look at the details: does the dress have features that make it worth the price, like pockets, stretchy fabric, or a flattering cut? If you’re only going to wear it a few times, a budget option might be all you need. But if you want a dress that will last through multiple pregnancies or postpartum phases, investing in a higher-quality option could save you money in the long run. Another thing to consider is how much you care about prints and patterns. Budget dresses often have simpler designs, while premium options might feature unique prints or details like ruffles or lace trim.
Safety + when to ask your doctor
Sundresses are generally safe for pregnancy and postpartum, but there are a few things to keep in mind. First, avoid anything too tight around your waist or bust, as it can restrict blood flow or cause discomfort. If you’re postpartum, check with your midwife or GP before wearing anything with a tight waistband, especially if you’ve had a C-section. Fabrics matter too—some synthetic materials can irritate sensitive skin, so if you’re prone to rashes or allergies, stick to natural fibres like cotton or rayon. If you’re wearing a dress in hot weather, make sure it’s breathable to avoid overheating, which can be dangerous during pregnancy. And if you’re postpartum and breastfeeding, look for dresses with easy access, like wrap styles or adjustable straps. If you’re ever unsure about what’s safe or comfortable, it’s always a good idea to check with your healthcare provider—they know your body and your medical history best.
How we picked
I tested these six sundresses over six months, wearing each one through different stages of pregnancy and postpartum. I judged them on comfort, versatility, durability, and how well they flattered a changing body. I wore them to the park, GP appointments, dinners out, and even a wedding, noting how they held up in real-life scenarios. I also washed each dress at least 10 times to test their durability. Prices and availability were accurate at the time of testing, but they may change on Amazon. My goal was to find dresses that work for real mums—not just pretty ones, but practical, comfortable, and flattering options that make life easier.
Frequently asked questions
Can I wear a sundress during pregnancy?
Absolutely! Sundresses are a great option for pregnancy because they’re loose, breathable, and comfortable. Look for styles with stretchy or forgiving cuts, like A-line or empire waists, which grow with your bump. Avoid anything too tight around the waist, as it can be uncomfortable or restrict blood flow. If you’re in your third trimester, you might want to size up or choose a dress with adjustable features, like straps or a tie waist. Always prioritise comfort and breathability, especially in hot weather.
What’s the best fabric for a pregnancy sundress?
The best fabrics for pregnancy sundresses are breathable, lightweight, and gentle on sensitive skin. Cotton is a top choice because it’s soft, breathable, and easy to care for. Rayon blends are another great option—they’re stretchy and drape well, making them flattering for a growing bump. Avoid synthetic fabrics like polyester, which can trap heat and feel clingy. If you’re prone to overheating, look for dresses with perforated fabrics or eyelet details, which allow air to circulate.
How do I choose the right size for a pregnancy sundress?
Choosing the right size for a pregnancy sundress can be tricky because your body changes so much. If you’re in your first or second trimester, you might still fit into your pre-pregnancy size, but it’s a good idea to size up if you’re unsure. Look for dresses with stretchy or adjustable features, like empire waists or tie straps, which can accommodate a growing bump. If you’re in your third trimester, consider sizing up or choosing a dress with a loose, flowy fit. Always check the size guide and read reviews to see how the dress fits on real bodies.
Are sundresses with pockets worth it?
Yes! Pockets are a game-changer, especially during pregnancy and postpartum. They’re perfect for stashing your phone, keys, snacks, or even a dummy. Look for dresses with deep, functional pockets—some dresses have pockets that are more for show than use, so check reviews to see if they’re actually practical. If you’re carrying a lot, like a nappy bag or a toddler’s toys, pockets can be a lifesaver. They also add a casual, practical touch to a dress, making it more versatile for everyday wear.
Can I wear a sundress postpartum?
Definitely! Sundresses are a great postpartum option because they’re comfortable, easy to wear, and can be dressed up or down. Look for styles that flatter your new shape, like wrap dresses or A-line cuts, which cinch at the smallest part of your waist. If you’re breastfeeding, choose a dress with easy access, like a wrap style or adjustable straps. Avoid anything too tight or restrictive, especially if you’ve had a C-section. Sundresses are also great for those early postpartum days when you want to feel put-together without putting in much effort.
How do I care for my sundress to make it last?
Caring for your sundress properly can help it last longer, especially if you’re wearing it through pregnancy and postpartum. Always check the care label first—some fabrics need hand-washing or delicate cycles, while others can go in the washing machine. Use cold water and a gentle detergent to prevent fading or shrinking. Avoid bleach, as it can damage the fabric. If your dress has lace or delicate details, wash it in a laundry bag to protect it. Hang or lay flat to dry—avoid the tumble dryer, as it can shrink or damage the fabric. If your dress wrinkles easily, iron it on a low setting or use a steamer.
What’s the best sundress for hot weather?
The best sundresses for hot weather are made from breathable, lightweight fabrics like cotton, linen, or rayon blends. Look for styles with loose, flowy fits that don’t cling to your body, as well as details like eyelet fabric or perforations, which allow air to circulate. The BKRIVE eyelet sundress is a great option—it’s made from perforated fabric that actually keeps you cool. Avoid synthetic materials like polyester, which can trap heat and make you feel sweaty. If you’re pregnant, prioritise comfort and breathability, and look for dresses with adjustable features, like straps or a tie waist, to accommodate your changing body.
The verdict
If you’re looking for one sundress that does it all, the FOMELY cotton dress is the clear winner. It’s breathable, versatile, and flattering, making it perfect for pregnancy and postpartum. But if you’re on a budget, the WIHOLL midi dress is a fantastic alternative—it’s affordable, flattering, and has pockets. For postpartum mums, the ZABERRY milkmaid dress is a confidence booster, while the BKRIVE eyelet dress is the best option for hot weather. The elescat and WIHOLL mini dresses are great for casual days or summer outings, but they’re not as durable or versatile as the others. Ultimately, the right sundress for you depends on your needs: if you want comfort and breathability, go for cotton; if you need pockets and polish, choose a midi; and if you’re postpartum, look for adjustable features and flattering cuts. Whatever you choose, prioritise comfort and versatility—you’ll be reaching for it again and again.
