What To Wear to a Wedding When Pregnant: 16 Stylish Ideas

Can you guess one of the most famous pregnant wedding guests in recent history?

Clue: the event was live-streamed by 72 million viewers worldwide, and a mom-to-be entertainer/celeb designer in attendance was in the top two among many best-dressed guests on that wedding day.

Answer: “Posh” Spice, aka Victoria Beckham! Expecting her fourth child when Prince William and Duchess Kate got married, Beckham’s dark, dramatic, and sensational look included a sophisticated fascinator and a custom pair of Christian Louboutins.

While her minimalist outfit remains a total fashion do, I don’t think an expectant mom needs to suffer in crazy-high Louboutins!

If you want tips on what to wear as a wedding guest when pregnant, I’ve got some yummy looks to show off your beautiful bump.

But, of course, if you’d rather keep your joyful news a secret, I’ll show you styles to hide your bump too.

We’re Focusing on Fashion Do’s

Gone are the days of tent-wearing moms-to-be, especially in the last trimester of pregnancy. But, of course, some women may want to camouflage their expectant status (remember the “is she or isn’t she” fuss over Meghan Markle at Princess Eugenie’s wedding?).

The focus is on wearing what makes you feel chic and beautiful, whether you want the world to know you’ve got a bundle of joy on the way or you’d rather not disclose your good news for the time being.

As far as what not to wear (again, insanely uncomfortable stilettos are a no-brainer!), I don’t think there are specific wedding guest fashion don’ts for pregnant ladies, no more than what any wedding guest shouldn’t wear out of respect for the bride.

Make It Perfectly Clear With a Bodycon Dress

Price point, comfortable material, exquisite details… everything about this perfect selection is what to wear to a wedding when pregnant!

The front-twist detail above the belly is super-chic, as are the colors available here: from dark green or grey to orange and mint-green, you should find a shade that works with your accessories and skin tone.

Fashion Do: The bodycon fit of this above-the-knee dress is excellent for a summertime, beach, or destination wedding, and the boat neckline is a classier look if you’re wary of showing deeper, distracting cleavage.

A Duster and Dress Makes a Fashionable Maternity Set

Buyers rave about this maternity set that combines function and style in an outfit you can separate and match with other pieces in your wardrobe and easily dress up for special events like weddings!

Check out how they’ve styled this look in navy or pink with sandals and a trendy sun hat. It’s the perfect wedding guest fashion when you’re pregnant.

Fashion Do: The Rayon/Spandex fabric blend includes light brushed cotton, and the dress has a form-fitted silhouette that favors comfort over cling. The loose, open-front duster (cardigan) features convenient side pockets too!

Pretty High-Low Maternity Dress Works for You

I like the color choice in this dress, and the floral pattern against the deep navy is especially pretty.

The fabric is described as super-soft, and that high-low hemline also shows a flash of your lovely legs.

Fashion Do: The expandable waistline works at every stage of your pregnancy and even after you deliver. So you can conceivably wear this dress long after pregnancy with a chic blazer or a wide belt!

An Infinity Dress Highlights Your Beautiful Bump

The longer-length and flowing infinity dress is a hugely popular look for bridesmaids, but it makes an equally stunning style for an expectant mom!

This premium quality dress is a poly-spandex and jersey knit blend that’s comfy and stretchy, highlighting your shapely glow without clinging. I also love the 24 jewel-tone colors available in this selection!

Fashion Do: Infinity dresses can be self-styled to flatter every figure, as shown in this beautiful photo courtesy of one of our Wedding Pioneer vendors!

Fitted Wrap Maternity Dress for a Formal Affair

This selection takes the best things about a bodycon style and an infinity dress to create a lovely look for moms-to-be attending a more formal wedding celebration.

While this is a very fitted dress, the length falls below the knee, so you don’t feel overexposed. The colors are great too, everything from soft pastels to sand, beige, and bright shades of mustard, aqua, and ruby.

Fashion Do: The off-shoulder wrap top offers semi-infinity dress possibilities and accents your collarbone and chest in a feminine way. The designer recommends a “no-show” panty for wearing underneath, and they offer a separate but coordinating slip to wear under this dress.

Get Your Glow on in This Flowing Maternity Dress

I adore this maternity look! With a high waistline, ruffled asymmetrical hem, and off-shoulder flutter sleeves, you get a soft and elegant wedding guest style available in burgundy, baby blue, or striking lime green.

Fashion Do: You will be so pretty in a romantic, flowing dress like this, especially if a bodycon fit makes you a bit self-conscious.

Linen and Cotton Dress With Layered Handkerchief-Hem

This refreshing dress is deceptively casual-looking, and the natural cotton and linen fabric mean day-long comfort.

The mid-length sleeves are effortless to move in as you enjoy the celebration, and there are abundant color choices—you might purchase a few of these dresses in different tones!

Fashion Do: I like how this look is styled with flats because it demonstrates how a layered handkerchief hem and soft, rounded neckline have enough dressy flair when you don’t feel like wearing a heel! This look is also easily accessorized with varying lengths of necklaces or earrings.

High Fashion Evening Dress Scores an A+

This selection is for my fashionista sisters who may want to keep their pregnancy news a secret for the time being. When you slide on this high-fashion design, you can keep your sweet little bump to yourself!

We’ve got another fabulous hem here with a draped, asymmetric billow. The slight open-collared neckline is super-chic, with longer, open-cuffed sleeves on a dress made of 85% comfy cotton.

Fashion Do: this cutting-edge style can be worn on so many occasions, and it’s up to you how much you need to accessorize this look because it’s already breathtaking!

Magical Wintertime Maternity Gown

A regal-looking floor-length dress with long sleeves and a high neckline is also super flattering.

Whether you’re attending a holiday celebration or a wintertime wedding, this dress is perfect for cooler temperatures, and it’s available in rich and extra-festive colors like olive green, silver, and royal blue.

Fashion Do: The glowing jersey velvet fabric will feel beautiful on you and also photograph exceptionally well! In addition, the designer includes a double fold of material built into the bustline, so you’ll feel safe and snug on top without sacrificing comfort or style.

Tencel Dress Gets a 10 for Great Eco-Friendly Fashion

I don’t see much chic maternity fashion made of 100% Tencel, a biodegradable fabric that requires less energy to make into clothing than conventional cotton.

The remarkable thing about Tencel is its soft smoothness, it’s a material you can enjoy wearing, especially when pregnant!

This loose-fitting garment with short sleeves and pockets comes in varied colors like cinnamon, pink, yellow and blue-grey. Extremely well-made, this is a look you can wear again at every stage in life.

Fashion Do: I love how this simple but versatile design is styled with strappy, open-toed sandals or ankle boots. It’s easy to accessorize this dress as a more formal look with glittery flats or get funky with a boho statement collection, including a standout necklace, chunky bracelet, and medallion ring!

Be a Yummy Mummy-To-Be in This Colorful Jumpsuit

When you crave bling blended with chic style, this maternity jumpsuit is two-thumbs-up with its sequined V-neck, bell sleeves just above the wrist, and fabulous, ankle-cuffed bell bottoms.

You’ll look gorgeous in a color choice like aqua, coral, fuchsia, purple, olive green, or yellow on a special occasion!

Fashion Do: The quality mix of polyester-spandex material showcases your pregnancy silhouette in an elegant, feminine way.

Supermom-To-Be in a Fantastic Cape Gown

The California-based designer of this stunning gown and cape says that celebrity fashion inspires them. This inspiration shows because the quality here is definitely celeb-worthy!

Your gown is made from a blend of materials (including bamboo!), and happy clients rave about its flowy, comfortable feel.

Fashion Do: The designer incorporates your custom changes into this design, and you can have it made to any size or length that suits you the best.

Strapless Style for the Mom-To-Be Wedding Guest

Soft and stylish, this quality knit top with black and ivory color blocking is fun, fashionable, and suitable to wear on casual or more formal occasions—now and after your baby arrives!

The stretch fabric provides coverage with a lovely cascading flow that dips lower at the back, and that bow is a sweet and sophisticated detail that really dresses it up.

Fashion Do: Next up, I found some tremendous fashion-forward trousers to pair with this strapless top to create a chic wedding guest look!

Wide Asymmetrical Trousers Are Maternity Fashion

Yes, these wide trousers have a comfy elastic waistband and are ideal for pregnant women. Still, they’re far from the typically casual maternity leggings that sometimes seem like your only choice in separates.

I also love that this style is available in two fabrics: soft, stretchy Lycra for warmer season weddings and a Jersey knit for cooler temperatures.

Fashion Do: The asymmetrical cut is so chic, and if you’d like to add a color splash to your outfit, check out the true red or smokey pink in Lycra and the mustard shade in Jersey knit!

Pretty Pink Maternity Dress Is Maxi Style

Here’s another striking choice of soft-quality knit in a decidedly hot pink color!

The black shoulder straps are on point, with a romantic flared hemline that flows as you move. I like the hint of a hi-low skirt here, too, because you can show off your chic wedding guest footwear.

Fashion Do: My favorite thing about this pretty pink dress is the ability to hide your bump (if you choose) or display it if you’re a bit farther along with your pregnancy. This dress is also a beautiful wear-again outfit for after your baby arrives!

Terrific Trench Coat Dress Offers Infinite Possibilities

It’s such a joy to find and feature gorgeous styles like this trench coat. It’s handcrafted from eucalyptus fibers into a silky, velvety fabric that comes in attractive colors like sand, mustard, dusty pink, or sky blue.

This style is comfortable pregnancy fashion at its finest. In addition, the designer offers free customization (raising or lowering the neckline, making the sleeves shorter, adding up to 12 inches to the length, or changing the waist seam placement). What a stunning choice!

Fashion Do: Yes, this is a trench “coat,” but you can easily accessorize it into a dress with its delicate tie details at the waist and the cuffs, or wear it as a cover-up over a shift dress. Either way, it’s easy to hide or show off your bump in this look!
