The Best Maternity Wedding Guest Dresses In 2025 For Every Stage Of Pregnancy (And All Seasons)

Hattie Brett, Grazia's Editor-in-chief says: 'I wore a polka dot version of this Asceno dress throughout my pregnancy - but it really delivered for events like weddings and work do's. The volumunious 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 the silk is beautiful quality and that's why - six years later - I still wear my version of this dress for easy, breezy summer holidays and beach days.'

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.'

Specialising in maternity fashion, Seraphine has some lovely dresses that will work during and after your pregnancy, giving you more bang for your buck. This button-through style with subtle puff sleeves has a flattering shaped empire seam at the front, while the elasticated back has a tie you can adjust for maximum comfort. If you're attending a wedding just after you've had your baby, the button-down nature of this dress also makes it perfect for feeding.

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.

Sophie Woodhouse, midwife and sister-in-law to Grazia's Jade Moscrop, wore an ASOS wrap dress to a 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.'

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.

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 pregnancy 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.

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.

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.

This pretty satin midi is actually two dresses in one, thanks to the fact that you can wear it as a twist-front halter neck or with a deep V-neck cinched at the waist. It has a relaxed A-line shape to maintain comfort throughout every stage of your pregnancy, and is available in this striking cobalt colour or a softer blush hue.

This loose-fitting slip dress comes with its own detachable cape, making it ideal for outdoor weddings when you need an extra layer. Size up for extra bump room to ensure it's as comfortable as possible – the position of the frills keep it flattering rather than fussy or overwhelming.

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 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.

All you'd need to do is add gold jewellery to this dress and it's wedding-ready for the minimalists among us. The puff hem adds detail and, pre or post-pregnancy, you could style with a belt if you prefer more of a cinched silhouette. The only thing I would say is that Mango's sizes are terribly limited – the brand considers a 12 to be a large – but hopefully the floaty nature of this particular dress means you could take your normal size. I'd recommend trying on in good time before your event so that you're not left in a state of panic if it doesn't work.

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 a 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.
