15 best maternity wedding guest dresses, according to post-partum editors
Wedding guest dresses can be arduous enough to source, never mind the best maternity wedding guest dresses. Unless you're the bride or groom, finding something to wear to upcoming nuptials while adhering to the many codes and formalities can sometimes feel like mission impossible. Add your new and totally unfamiliar body shape to the mix and you might just send yourself into an early labour…
To save you from the stress - which, let's be honest, as mum-to-be, we've already got more than enough of - we've done the hard work for you.
The best maternity wedding guest dresses, at a glance:
Glamour's Senior Beauty Editor, Elle Turner, and Freelance Fashion Editor, Charlie Teather, have both recently become new mums, and we found ourselves in this exact predicament more than a handful of times. With several weddings to attend that saw us on the hunt for bump-friendly occasion dresses that A) make us look and feel great, and B) were super comfy, we took on the challenge so you don't have to.
“It's so hard to find wedding guest dresses specifically for when you're pregnant, but Club L London was one of the few places I came across with modern options designed to accommodate bumps, with non-frumpy silhouettes and pretty colours and patterns. Blue florals are a forever fave, but they also have loads of options in soft pinks, baby blues, butter yellows and more,” Elle says.
The Lita asymmetric maternity maxi dress you see her wearing above comes in four other colours, and also comes in a non-maternity shape (just in case you're looking for summer wedding guest dresses sans bump!). Its premium stretch jersey hugs every curve, boasting a twisted, one-shoulder neckline and a heel-grazing hemline that you could easily pair with comfy heels or flats.
Elsewhere, if you don't mind investing a bit more, Bumpsuit have a gorgeous brushed satin gown that drapes over your figure instead of hugging it. Bonus points: it would be perfect for postpartum, too.
Looking for something a bit more modest, or perhaps a spring wedding guest dress while it's still cooler out? H&M have this balloon-sleeved maxi dress that looks far more expensive than its £65 price tag, while River Island have got you breastfeeding mums covered with this satin maternity wrap midi in baby pink. PSA: It's currently on sale for £20.
So, while you might be contemplating how you're going to get through the speeches and dancing without a glass of fizz in hand, you certainly shouldn't be worrying about what to wear. There are plenty more bump-friendly wedding guest dress options available below, from both dedicated maternity brands as well as your favourite online clothing stores.
Why you can trust us
Glamour's Senior Beauty Editor, Elle Turner, and Freelance Fashion Editor, Charlie Teather, have both become first-time mums over the last year or so, and – alongside, you know, prepping for one of humankind's toughest physical feats and the subsequent life-altering reality of a tiny new human to care for 24/7 – rediscovering how to dress a body that was changing every single day posed a real challenge.
We didn't want to lose our personal style identities, but we also wanted to celebrate and not just ‘disguise’ this incredible moment in our lives. And if we were finding this balance hard to strike, after working our whole adult lives in the fashion and magazine industry, we figured others must be too. So, we made it something of a personal/professional mission to compile the ultimate maternity fashion guides. If for nothing more than for us to refer back to if/when we ever do this pregnancy thing again, because (spoiler alert) baby brain is no joke, people…
How we tested the best maternity wedding guest dresses
Elle and Charlie used their own pregnancies as the perfect excuse to trial run the best maternity styles out there and compile this edit. We all shopped from independent, designer and high street maternity brands during our second and third trimesters (with varying success), and have also asked our well-dressed pregnant pals and new mums for their top tips to find high-quality maternity wear. Not to mention, we've scoured Instagram for the ultimate inspiration too. For mums-to-be, Glamour's edit of the best maternity wedding guest dresses of 2025 is essential reading…
Ahead: pregnant editor-approved maternity wedding guest dresses to wear in 2026.
Why we love it: Effortless, chic, timeless, flattering… Need we say more? This is a really gorgeous option if you're less keen on anything too tight around your bump, and is a really easy one to dress up with a statement necklace and bag, or keep simple and effortless by skipping the accessories. It'll also work just perfectly post-partum too, which is ideal if you're anything like us and have 100,000 weddings on the horizon.
Size range: XS-XL.
Why we love it: For those who tend to steer towards more form-fitting silhouettes in pregnancy (and, spoiler: that's not always exclusively the people who did so pre-prengancy, as we can attest to being completely converted to them once pregnany!) this olive green dress is such a beautiful autumn/winter option. Plus it's high-neck, which is something to make the most of now if you're planning on breastfeeding once the baby's here…
Size range: 8-16.
Why we love it: Red may not be a colour frequently spotted amongst the guests at a wedding, but we'd like to see that change. After all, it is the official colour of love… This one's knotted neckline and draping is super flattering over a baby bump, and the length is perfect for anyone fearful that a full-length number just adds a trip hazard to proceedings.
Size range: XS-XXL.
Why we love it: A classic wedding style dress that's often chosen for bridesmaids (Charlie opted for something very similar for hers), there's something to be said for the universally flattering silhouette of this flowing, slinky dress. It may not be strictly maternity, but that makes it even better. Size up and it should be perfect for you right now and during your postpartum journey.
Size range: 4-18.
Why we love it: This dress screams effortlessness, and is such a comfy thing to throw on without feeling sloppy. The elevated high neck, sleeveless style and draping at the neckline make it feel appropriately fancy for the occasion, while the loose fit and soft fabric ensure maximum comfort.
Size range: 6-20.
Why we love it: While the thin spaghetti straps may scream summer, the deep burgundy hue is perfect for this time of year. Another great one to wear and re-wear, it'd be perfect this season with a similarly deep, sweeping coat or caped scarf, which you can switch out for nothing more than a little sandal come spring. Handily, the gentle stretch of the ruched mesh across your bump will grow as you do.
Size range: XS-XXL.
Why we love it: If you're in the mood for a little Grecian goddess action, this balloon-sleeved maxi is the perfect pick. Flowy and flattering, it may well be the most comfortable maternity wedding guest option out there.
Size range: XS-XXL.

Why we love it: Florals are a classic wedding guest style, but they can often feel a bit cliché or frumpy - particularly when you add a baby bump into the mix. The asymmetry of this one's straps, the modern-feeling twists, and the slim-fit silhouette, however, set this one apart from its contemporaries, and render it the ideal pick for upcoming nuptials.
Size range: UK 8-16.

Why we love it: Appropriately festive without screaming ‘Jingle Bells’ too loudly, this abstract print red dress is a great choice for those who want something comfortably loose-fitting over the bump. The long sleeves are aesthetically appropriate for this cold weather, while the sheer fabric means that they're breezy enough not to overheat a likely-already-overheating pregnant body.
Size range: UK 6-20.

Why we love it: Perfect for summer, this is a great option to buy now if you've just had a summer wedding invitation and found out that your pregnant. You'll have a pretty blooming bump by then, and you'll be grateful to winter-you for planning ahead.
Size range: UK 10-20.

Why we love it: Wrap dresses are so great at this stage of life, because not only do they work throughout the entire pregnancy thanks to the adjustable nature but they're also great postpartum too if you're considering breastfeeding. This pale pink satin iteration is perfect for weddings, as it's soft and romantic but also really comfortable for what is likely going to be a relatively long day.
Size range: UK 6-18.

Why we love it: A really beautiful maternity option, this deep blue floral dress is another one that works well whatever the season. Paired with a long navy coat and pointed court shoe right now, or bought with a summer wedding in mind when you'll be in your third trimester to pair with a strappy (comfortable, crucially!) sandal, it's an effortless silhouette that simultaneously skims and hugs your bump.
Size range: UK 6-20.
Why we love it: If you're expecting a girl next summer, and are feeling sentimental and touch cliché, then this dress should be on the top of your shopping list - whether you've received a wedding invitation or not. The shirring detailing is a nice accent to sit above the bump, or skim over your postpartum belly for any post-baby summer plans.
Size range: XS-XL.
Why we love it: Navy is a popular colour choice for winter weddings, but this polka dot fabric adds a little something extra. With a button-up front, it's another great option to rewear postpartum for those hoping to breastfeed.
Size range: UK 6-20.

Your maternity wedding guest dress FAQs, answered:
Where I can buy a maternity wedding guest dress?
This totally depends on your personal style, but generally H&M and ASOS are both great places to start for more affordable options with a wealth of different maternity silhouettes. If you prefer a super form-fitting shape then Club L London offer some great options, while Bumpsuit has a particularly great selection of strapless, timeless dresses.
What wedding guest dress shape is best in pregnancy?
The beauty of pregnancy dressing is that you can really push the boundaries of your usual style. Sure, you might not want to go too rogue, but our editors found that - despite previously favouring a looser dress shape - pregnancy actually saw them steer towards bump-hugging, form-fitting styles far more often. So don't just presume that because you always wear one shape that that's what you'll stick to throughout pregnancy. No one silhouette works for everyone, never mind during pregnancy, so have some fun with it and experiment with looks you'd never previously have considered.
