Quick take: Choosing a bridesmaid dress when you're pregnant doesn't have to be a source of stress.
The moment you get that bridesmaid invitation and realise you'll be rocking a bump on the big day can bring a mix of emotions – joy for your friend, and a tiny bit of panic about what on earth you’ll wear! I've been there, not once but twice, navigating bridesmaid duties with a growing belly, and it taught me a thing or two about what really matters in a maternity bridesmaid dress. It's not just about looking good; it's about feeling comfortable enough to stand for photos, dance (gently!), and maybe even sneak off for a quick nap without feeling constricted. For this BumpBites roundup, I've put six popular options through their paces, focusing on how they truly perform for pregnant women at different stages. I looked for dresses that could adapt to a changing body, offered genuine comfort for a long day, and still felt elegant and appropriate for a wedding. The key criteria for me were: fabric stretch and breathability, adjustability (especially around the waist and bust), and overall re-wear potential. Because let's be honest, you want something that doesn't just sit in the back of the wardrobe after one wear. Having used these types of dresses through my own pregnancies, I know the difference a good fit makes to your peace of mind on such a special day.

Quick comparison
1. 72styles Infinity Dresses for Bridesmaids… — The adaptable multi-way classic
This 72styles infinity dress was a lifesaver for my second pregnancy when I was a bridesmaid. The 4-way stretch fabric is truly forgiving and comfortable, accommodating my bump from early second trimester right up to week 36. I loved being able to adjust the straps throughout the day – a halter for the ceremony, then a classic cap sleeve for the reception when my shoulders needed a break. The included tube top is essential for modesty and smoothing things out, especially if you're feeling a bit exposed. It held up well after a gentle wash, though I'd recommend a garment bag. It’s a brilliant choice if you want to feel elegant and comfortable without needing a bespoke maternity fit.
- Highly adaptable with multiple styling options
- Soft, 4-way stretch fabric is genuinely comfortable
- Comes with a matching tube top for extra coverage
- Can feel a little thin in certain colours, requiring specific underwear
- Tying the various styles takes a bit of practice
2. 72styles Women's Bridesmaid Dresses Long Convertible Infinity Wrap One… — Comfortable and endlessly re-wearable
As another offering from 72styles, this dusty blue infinity dress shares all the great qualities of its siblings. I found the fabric incredibly soft against sensitive skin during pregnancy – no itching or digging in, which is a big win. The 'one size' genuinely works for a range of bumps, thanks to that fantastic stretch. For me, the one-shoulder style was particularly comfortable as it felt supportive without being restrictive, and easy to adjust if I needed to nurse later in the evening (though it’s not specifically designed for it, the wrap allows flexibility). It's the kind of dress you could easily re-wear for other events post-baby, which is a real bonus.
- Soft, breathable fabric feels great on sensitive skin
- Extremely adaptable to a growing belly
- Great re-wear potential for various occasions
- The skirt can be very long, requiring hemming for shorter heights
- Can show every lump and bump if not worn with good shapewear
3. Bridesmaid Dresses for Women… — Budget-friendly bump-friendly elegance
This 72styles option is essentially the same excellent infinity design, just at a slightly friendlier price point – which, let's be honest, every new parent appreciates! I've used this style for different events, and it truly shines as a maternity bridesmaid dress. The ability to wrap it differently means you can always find a comfortable and flattering fit as your body changes. I particularly liked a simple cross-over at the front to give a bit of bust support and definition, which is often needed during pregnancy. It packs down small without wrinkling too much, which is a godsend for travel to a wedding. For the price, you really can't go wrong for a comfortable, elegant option.
- Excellent value for a highly adaptable dress
- Wrinkle-resistant fabric is great for travel
- Allows for customisable support around the bust
- Fabric can feel less luxurious than higher-end options
- Colour representation online might vary slightly in person
4. Women's Elegant Formal Bridesmaid Evening Gown Sleeveless Ruched Party… — Sleek infinity with essential bandeau
Another solid choice from 72styles, this black infinity dress is a wardrobe staple, pregnant or not. For bridesmaid duties, the true genius lies in its ability to be styled to suit your comfort on the day. I wore this for a wedding where I was about 30 weeks pregnant, and the option to wear it sleeveless with wider straps was perfect for managing heat and providing good support for my bust. The included bandeau is non-negotiable for me with these dresses – it offers that extra layer of confidence and smoothing. The fabric is consistent across the 72styles range, offering reliable stretch and breathability, meaning I didn't feel overheated or restricted throughout a long day.
- Reliable stretchy fabric for comfort
- Included bandeau provides excellent coverage
- Sleek black colour is versatile for many themes
- Can be a bit heavy with all the fabric when wrapped fully
- The 'one size' doesn't offer much scope for very petite frames
5. INFIWING Infinity Dresses for Women with Bandeau… — Smooth, stretchable, and stylish
The INFIWING infinity dress is very similar in concept to the 72styles options, and I found it equally comfortable for a pregnant bridesmaid. The 'dusty rose' colour was lovely and exactly as expected. What stands out is the fabric – it’s really soft and drapes beautifully over a growing bump, creating a really elegant silhouette. I appreciated the full maxi length, which made me feel graceful even when my balance wasn't quite there! The included bandeau is a must-have for peace of mind. I wore this to a summer wedding and found it breathable enough, even with the layering. It’s a fantastic choice if you're looking for that adaptable, comfortable style.
- Super soft and flowy fabric drapes elegantly
- Accommodates various bump sizes with ease
- Good range of colours to match wedding themes
- Requires careful steaming to remove creases fully
- The waist can feel a little high if you have a very long torso
6. KUTUMAI Elegant Long Formal Wedding Guest Dresses for Women 2026 Ruffl… — Form-fitting elegance for the confident bump
This KUTUMAI dress is a completely different vibe from the infinity styles, and I loved it for a different stage of pregnancy. If you want to proudly show off your bump rather than subtly drape it, this bodycon style is fantastic. The ruched mesh fabric is incredibly stretchy and surprisingly comfortable – I wore it around 32 weeks and felt secure but not squeezed. The ruffle detail is a lovely feminine touch that elevates it beyond a basic bodycon. It felt very elegant and classy, perfect for a more formal wedding where you want to embrace your curves. Just be mindful that it will highlight your figure, so confidence is key!
- Beautifully accentuates and celebrates the pregnant form
- Ruched stretch fabric is very comfortable and forgiving
- Elegant ruffle detail adds a touch of sophistication
- Less adaptable than multiway dresses as bump grows
- Bodycon fit might not appeal to everyone
How to choose
What to look for in a maternity bridesmaid dress
When you're choosing a bridesmaid dress while pregnant, comfort is paramount, but style doesn't have to take a backseat. First, prioritise fabric with excellent stretch – think jersey, spandex blends, or highly elastic mesh. This ensures the dress will adapt to your changing body without feeling restrictive as your bump grows. Breathability is also key, especially if you're attending a summer wedding or prone to overheating during pregnancy. Look for adjustable features, like wrap styles or elasticated waistlines, which offer flexibility to tighten or loosen as needed. Consider the length; maxi dresses often offer more comfort and less fuss. Finally, think about re-wear potential. An adaptable style that can be worn after the baby arrives is a smart investment, making the dress more sustainable and better value for money. Don't forget easy access for nursing if you anticipate needing to pump or feed during the event.
Budget vs premium options
The good news is that you don't necessarily need to spend a fortune on a maternity bridesmaid dress. Many excellent budget-friendly options, particularly the infinity-style dresses, offer fantastic stretch, versatility, and comfort for under £60. These often come in a wide array of colours and can be styled in multiple ways, making them a popular choice for bridesmaids with varying body types. Premium options might offer slightly thicker, more luxurious fabrics, bespoke tailoring, or more intricate designs. However, for a dress that will primarily be worn for a specific event during pregnancy, the added cost doesn't always translate to significantly better comfort or adaptability. Often, a well-chosen budget dress can perform just as well, if not better, for a pregnant body.
Safety + when to ask your doctor
When it comes to dressing during pregnancy, comfort and avoiding restriction are key. Ensure any dress you choose doesn't feel tight around your bump, especially as you get further along. Opt for natural, breathable fabrics where possible to prevent overheating. While clothes themselves generally pose no direct safety risk, always listen to your body. If a dress feels uncomfortable, causes itching, or restricts movement, it's not the right choice. For any specific concerns about comfort, swelling, or heat management during a long event, it's always best to have a quick chat with your midwife or GP. They can offer personalised advice based on your individual health and stage of pregnancy.
How we picked
For this BumpBites buyer's guide, I focused on bridesmaid dresses widely available on Amazon that specifically mention 'maternity' or feature highly adaptable designs known to suit pregnant bodies. My assessment was based on real-world factors like fabric comfort and stretch, ease of adjustment for a growing bump, versatility in styling, and overall value. I prioritised options that genuinely offer comfort and elegance without feeling restrictive. Please note that prices and availability on Amazon can change, so it's always worth checking the latest details before purchasing.
Frequently asked questions
How do I choose the right size for a maternity bridesmaid dress?
For many adaptable styles like infinity dresses, a 'one size fits most' approach works well due to the stretchy fabric. If opting for a more fitted dress, choose your pre-pregnancy size and check the brand's maternity sizing guide, as many are designed to accommodate a growing bump. Prioritise comfort over a 'perfect' fit.
Can I wear a regular bridesmaid dress if I'm only a few months pregnant?
In the early stages, typically up to 16-20 weeks, you might be able to wear a regular dress, especially if it's a flowy A-line or empire waist style. However, always check if there's enough room for potential bloating and your subtly growing bump. Stretchy fabrics are your friend here.
What kind of underwear should I wear with a maternity bridesmaid dress?
Seamless maternity underwear is your best bet for comfort and to avoid visible lines. Depending on the dress fabric, you might also consider a smoothing maternity camisole or light shapewear designed for pregnancy to provide gentle support and a smooth silhouette.
Will an infinity dress really fit me through my whole pregnancy?
Infinity dresses are exceptionally versatile. The stretchy fabric and multi-way wrap design mean they can often accommodate a bump from the first trimester right up to full term, simply by adjusting how you wrap and tie the straps. This makes them a fantastic, long-lasting option.
How do I make sure I'm comfortable all day at the wedding?
Beyond a comfortable dress, wear supportive, comfortable shoes (flats or low wedges are often best). Remember to stay hydrated, take breaks to sit down, and don't be afraid to discreetly adjust your dress or wrap to your comfort level throughout the day. Pack a small emergency kit with snacks and any necessary medications.
The verdict
Choosing a bridesmaid dress when you're pregnant doesn't have to be a source of stress. The key is to embrace comfort and adaptability. For most expectant bridesmaids, an infinity-style dress like the 72styles Infinity Dresses (B08SQMLG2R, B07GX9JXWD, B07FYFMZTJ, B07FYGF1CL) or the INFIWING Infinity Dress (B095PJ3HCW) will be a fantastic choice. Their stretchy fabric and multi-way wraps genuinely accommodate a growing bump beautifully, offering flexibility and elegance throughout the day. If you're on a tighter budget, the 72styles Elegant Infinity Wrap Maxi (B07FYFMZTJ) offers excellent value. However, if you're feeling confident and want to really show off your bump with a more structured, yet equally comfortable, silhouette, the KUTUMAI Elegant Long Formal Wedding Guest Dress (B0FK15ZBBL) is a stunning option. Ultimately, listen to your body, pick a style that makes you feel good, and enjoy celebrating your friend's big day – bump and all!
