The Best Maternity Wedding Guest Dresses, Tried And Tested For Every Trimester

Rebecca Holman, Grazia's digital director says, she wore a lot of H&M's Mama range throughout both of her pregnancies. 'I first discovered this maternity range when I was panic buying a dress for a wedding while pregnant with my first child. I ended up finding something that looked a lot like this dress (but was slightly different – this was years ago now!) and not only did I feel completely like myself and really comfortable for the whole day, I also received so many compliments. It was a bit of a fluke but, since then, I've worn several H&M dresses while pregnant and think they're really great in terms of fit and shape.'

Hattie Brett, Grazia's editor-in-chief says, 'I wore a polka dot Asceno dress throughout my pregnancy - it really delivered for events like weddings and work dos. The voluminous shape means it's airy for summer events with a big bump, but the neckline gives it an edge and meant I could still show off a bit of skin, which helped me feel like me in the latter stages of pregnancy. If you're worried about the bra situation, I wore a sports bra, which was also really comfortable. It's expensive for sure, but it's of beautiful quality and that's why - years later - I still wear my version of this dress for easy, breezy summer holidays and beach days.'

Charlotte Rogers, PR director (and friend of Grazia's Hannah Banks-Walker) chose Rixo for a wedding when she was five months pregnant and says: 'I love this dress for the cut and the flow. It’s flattering around the middle, whether you’re pregnant or don’t want something tight-fitting around your tummy. I didn’t want anything tight at this stage in my pregnancy – I wanted something I would normally wear to a wedding. The staff at the Rixo store were incredibly helpful; I told them I was pregnant and they gave me lots of advice without being overbearing. I felt so comfortable in the dress and have since worn it to two other weddings when I haven’t been pregnant. I’m normally a size 10 but bought a 12 in this just so that it was as loose as I wanted it to be. I wish I could buy this in every colour.'

While Charlotte's exact dress is no longer available, Rixo has this very similar midaxi style that has a loose shape which can be adjusted using the waist ties. Just like Charlotte, we'd recommend sizing up if you're after a looser, more comfortable fit.

Anne Lora Scagliusi, fashion commerce writer, says, 'When I was pregnant, I’d head straight to the Nobody’s Child racks to check out their bump-friendly styles. I've never been much of a fan of traditional maternity wear. I’ve always been strategic about picking pieces that grow with me, and one style I absolutely loved was the Nobody’s Child Nova Midi Dress. I adore this dress because it comes in different prints and colourways season after season, remains one of their standout designs, and works beautifully postpartum too, making it a genuinely sustainable choice.

'The Nova Midi is seriously dreamy. Puff sleeves, a square neckline, and a pleated bodice mean it’s flattering without feeling tight around your bump. The shirred back makes it super comfy, and the full A-line skirt with pockets is just so practical. I love it in this romantic black with embroidered florals, made from lightweight 100% organic cotton, it’s perfect for sunny weddings, garden parties, or just a casual summer day out.'

Anne Lora Scagliusi, fashion commerce writer, says, 'I rarely find a dress that makes me feel like my pre-baby self, but this ARRANGE Pop-Pink Corseted Maxi comes close. The vibrant shade is such a mood boost, and while 'corset + bump' sounds scary, the textured bodice gives shape without pinching. The bandeau neckline stays put, the back zip makes it easy, and the whole thing strikes that sweet spot between structured and comfy. Perfect for weddings, date nights or glam brunches, it doesn’t fight your bump, it flatters it, while still feeling like you.'

Sophie Woodhouse, midwife and sister-in-law to Grazia's Jade Moscrop, wore an ASOS wrap dress to Jade's wedding while she was heavily pregnant. She says: 'I was 34 weeks pregnant and, while my dress wasn't actually a maternity dress, it had a tie-side which meant I could wear it during pregnancy and afterwards. It’s great for breastfeeding, too, thanks to the easy access. The chiffon-type material was nice and airy on an extremely hot day. I loved the floral print, perfect for wedding season, and I can easily dress it up with heels or dress it down with Birkenstocks or trainers.'

Anne Lora Scagliusi, fashion commerce writer, says, 'I’m not usually one for overly ‘maternity’ pieces, but the Outline Maxi is one of those dresses that makes you feel instantly put-together. The ruching is genius, it hugs your bump in the right way without feeling clingy, and the stretch jersey moves with you (so no awkward wriggling in and out). Plus, the lemon yellow is such a mood-lifter. I’d wear this for a baby shower or any occasion where you want to feel glamorous but still comfortable, you just throw it on, add some gold jewellery, and honestly, you feel like sunshine.'

If you’re after a maternity wedding guest dress that’s as comfortable as it is chic, this light blue chiffon midi is a winner. The tiered shape gives you plenty of room to grow, while the lightweight fabric ensures you won’t feel weighed down. It won’t cling uncomfortably to your bump, moves effortlessly whether you’re walking or dancing, and layers easily with a shawl or jacket if the weather changes, making it ideal for all-day events.

The best part? It’s breastfeeding-friendly too, so you’ll still get plenty of wear out of it once baby arrives. The soft pastel hue is perfect for summer weddings, garden parties, or even a sunny destination ceremony. It could also be the perfect baby shower dress if you’re after something elegant yet easy to wear. Just add strappy heels or flat sandals and a pair of gold earrings, and you’re ready to go.

A statement-making dress with vibrant patterns and flowing ruffles that move beautifully with every step. The long, strapless silhouette is playful yet elegant, making it perfect for outdoor or summer weddings. Pair with simple sandals or heels to let the dress do all the talking.

The relaxed, off-the-shoulder silhouette and stretchy plissé fabric make it comfortable to wear all day, while the elasticated waistband defines your shape in all the right places. Subtle gold flecks and a delicate lettuce hem catch the light beautifully, making it elegant yet easy to style.

While this isn't specifically maternity wear, the oversized silhouette and curved waist of this dress make it a great choice for weddings or special occasions while you're pregnant. It's lightly lined, so the fabric falls nicely and, as the brand recommends sizing down, you can afford to get your normal size or a size bigger depending on how loose you'd like it to be. You can also wear this way beyond pregnancy – the '70s-inspired shape and details are timeless.

This one is pure romance and so easy to wear. The soft lilac hue feels dreamy, and the elasticated bodice means it gently stretches over your bump without digging in. Adjustable straps keep it comfy as you grow, and the floaty maxi skirt moves beautifully. It’s one of those dresses that turns heads but feels effortless, you and your little one will both be glowing in this.

Who says maternity dressing has to mean floaty and shapeless? The Darcie proves otherwise. This is the dress for when you still want all the sleek lines, all the drama, and all the comfort in one go. With its asymmetric neckline and chic double-strap detail, it’s giving instant wow without even trying. The fit is gloriously figure-skimming, hugging your bump in just the right way, while the clever side ruching means it grows with you through every trimester. Made from sustainable viscose, it’s one of those rare maternity pieces that feels as good as it looks.

The Shiloh feels like the kind of dress you can actually live in while still feeling effortlessly chic. I love how the fabric drapes over your bump without feeling tight or awkward, it just skims in all the right places. Honestly, this one makes you feel polished without trying too hard. Its relaxed, easy silhouette works perfectly for a summer wedding, a party, or even a brunch when I want to feel a little extra special.

If you want free, flowy, and fabulous, this is it. The Mango Mambo Maxi has such a playful vibe with its floral-adorned top and pleated skirt that swishes with every step. The smocked back gives you stretch where you need it, so the bump has space to breathe, while the V-neckline keeps it flattering and feminine. Each dress has its own unique tie-dye finish too, which makes it feel that bit more special.

If you're looking for an oversized dress that you can wear during and after pregnancy, this & Other Stories has the perfect loose fit that will work for any stage of pregnancy – and any season, for that matter. Designed to be roomy, if you're heavily pregnant and want even more space, opt for the size up. You could always have it taken in afterwards, so you can continue wearing it for weddings in the future.

Sometimes all you want is a dress that lifts your mood the second you slip it on, and this FARM Rio maxi does exactly that. The bold red and playful eyelet detailing make it a real standout, while the puffed sleeves add a festive, dramatic touch without going over the top. The best bit? It doesn’t restrict the bump area at all, so you feel comfortable as well as fabulous. The square neckline keeps everything balanced and elegant. I love that it has that dreamy ‘holiday evening’ vibe, but it’s just as perfect for sunny summer days when you want to look effortlessly dressed up with zero effort.

Not only is this super glamorous, it's also one-size-fits-all, which means you can wear it while pregnant, postpartum and beyond. Don't let the idea of one size put you off, though – this dress comfortably fits those who are between a size XSmall-XXLarge and all body shapes. The fabric is lightweight, which will be particularly comfortable during pregnancy, as it's 100% linen. You will need to ensure you invest in a great strapless bra, however, to provide good support.

Sister Jane is my go-to when I want something fabulous but bump-friendly, and their puffball hem dress and empire waistline selection never disappoint. The River Flower Midi has this soft woven fabric that just skims over the bump without any fuss, and the crochet flower trims add such a pretty, girly touch. It’s the kind of dress that makes you feel fresh and feminine even on days when you’re not feeling your best. I love that it’s versatile too, you can wear it to brunch, a party, or just out in the sunshine and still feel like you’ve made an effort.

If you buy this dress in a size bigger than usual (or even two if you're very pregnant and want something oversized and breezy for hot weather), you'll find this will be perfect for summer or destination weddings. All you need to add is a pair of flat sandals, a chunky gold necklace and you're ready to go.

Due to the V-neck and gathered detail under the bust, you'll find this is great for a growing bump, although you may need to choose a size larger than usual. The half length puff sleeves and earthy tones make it an ideal choice for autumn weddings, as Hannah Banks-Walker suggests: 'While I'm not pregnant, I do have several of Farm Rio's dresses and can attest to their high quality. They feel so lovely to wear and, what I love about this dress in particular is that you could dress it up or down for various events, whether you're pregnant or not.'

With its long sleeves, moody florals and black bow details, this dress would be an ideal choice for any winter weddings. It has a fairly flowy silhouette but you may still want to size up for comfort during your pregnancy. Just add maternity tights and some black pointed flats.

Whether you're in the early or late stages of pregnancy, this dress will be just as comfortable. It's brilliantly oversized with an off-shoulder neckline that ensures it doesn't become shapeless or unflattering, realised in a beautiful dark green taffeta perfect for any kind of wedding throughout the year. You can add a cropped jacket when it's colder or just wear with flat sandals for summer events.

Dressed up with gold jewellery and great shoes, this easy gingham dress from New Look's maternity range would make a great wedding guest dress. It will also be brilliant for hot summer days when you just want to be comfortable, plus it will work postpartum, too. Not bad for a dress that's under £40.

The brand many celebrities turn to during pregnancy, Bumpsuit doesn't just make great maternity basics, there's a selection of evening dresses, too. Made from a super-soft stretchy jersey, this off-shoulder dress is, like all of Bumpsuit's pieces, made to gently stretch with the body through the stages of pregnancy. This means you can wear it pre, during and post-pregnancy (the brand recommends taking your usual size), giving you great value for money. It's also double lined for extra support.

With a high waistline, cape silhouette and pleats, this dress offers a stylish way to dress your bump that won't feel in any way restrictive or uncomfortable. It's a very wedding-friendly rose pink and is available in sizes 4-30, too.

Club L London has a dedicated maternity section that's full of dresses in classic shapes and colours to suit any kind of wedding. This square neck midi is made of premium stretch jersey for extra comfort and has a timeless shape with pretty bow details on the cap sleeves. The brand's size range is not as extensive as it could be – it offers this dress in sizes 8-16.

With its naturally loose shape, this dress will work pre, during and post-pregnancy, whether you're attending weddings or going on holiday. It comes with a slip to wear underneath which is more form fitting, so while pregnant you may want to wear your own maternity slip for extra comfort. It's made of a light, breathable cotton and the pretty jacquard detail makes it feel extra special.

You will need to size up in this dress if you want to wear it throughout pregnancy, but there is 2% elastane added to the cotton so it has some stretch if not a lot. The ruched detail around the waist, however, will frame your bump in the best kind of way, while the lightweight cotton is breathable (read: comfortable on warm/hot days). You don't have to save it for summer either – just add an oversized jacket in colder months and it still works.

A dropped waist, interestingly, offers a timeless silhouette that's also great for accommodating a pregnancy. The V-neckline has a pretty tie detail (mirrored on the back) and you'll find you'll want to wear this for weddings for years to come – it's easy, comfortable and super-stylish. Take the size up if you're unsure; it's meant to be slightly oversized anyway.

Hannah Banks-Walker, head of fashion commerce, says, 'I've come to rely on Sister Jane for events as the brand makes stand-out dresses that are unique and timeless. I've worn several styles to various weddings and always receive compliments. This style would be ideal if you're pregnant – it's oversized enough to accommodate your bump but far more fabulous than a lot of the maternity options I've seen on offer.'

Made from recycled polyester, this dress can be worn on or off the shoulder, depending on how you feel or which season you're in. Also available in mauve and a light floral print, the red iteration is great for weddings and means you can afford to keep the rest of your outfit fairly pared back. The silhouette allows room for your bump, plus the elasticated neckline makes this dress a good option for events post-pregnancy if you're breastfeeding.
