What to Wear to a Wedding When Pregnant

When it comes to maternity wedding guest outfits, there’s a lot to consider. From choosing the right size and accessories to avoiding fashion faux pas, it can all feel a little bit stressful—to say the least. But it doesn’t have to be! Here are some handy tips and tricks to keep in mind when shopping for cute maternity dresses for weddings.

Check the dress code: Always check the invite to see what the dress code is before you make a purchase. If it’s a black-tie event, you’ll need a formal dress; for more laid-back affairs, you can opt for something contemporary and casual.

Consider the season and the location: Once again, check the invite to see where the ceremony and reception will take place. If it’s a summer beach wedding, choose airy, natural fabrics that’ll keep you cool. Alternatively, if you’re attending an outdoor wedding in winter, be sure to wrap up appropriately.

Look for a pregnancy-friendly fabric and silhouette: The style you choose will always come down to personal preference. That being said, there are two classic (and universally flattering) pregnancy dress styles that we love. An empire waist gown (a dress that’s cinched under your bust) is a failsafe option that provides ample room for your bump. A sheath dress (a fitted style with a nipped-in waist) is another wonderful choice for moms-to-be that want to show off their curves. When it comes to fabric, look for breathable material that has a little bit of stretch to ensure a comfortable fit (think: cotton, jersey or chiffon).

Check the size guidelines: If you’re shopping in a store, ask for advice from the in-house experts as you may need to go up a dress size to accommodate your growing baby bump. Alternatively, if you’re shopping online, read the brand’s size guidelines and reach out to customer service if you have any questions.

Wear comfortable shoes: Skip the sky-high heels and go for comfortable, supportive and stylish shoes that you can dance in all night long.

Consider budget: Opting for a maternity wedding guest dress you may only wear once? You will probably want to rein in your budget. However, if you’re going for a style that can be worn during and after pregnancy, you can more readily rationalize the splurge.

Where to Shop for Maternity Wedding Guest Dresses

Searching for dreamy maternity dresses to wear to a wedding? Get ready to celebrate as there are tons of gorgeous options available online. Here are four of our favorite places to rent or buy stylish, party-ready pregnancy apparel.

HATCH Collection: HATCH Collection is always a top choice when it comes to finding high-quality maternity attire. We adore their stunning collection of maxi and midi dresses made from sumptuous fabrics in jewel tones. The best part? Many of the brand’s frocks are post-bump friendly, meaning you get serious cost per wear.

Seraphine: Fashion-conscious mamas will definitely become familiar with Seraphine. This brand, loved by celebrities and royals alike, covers all the bases with a selection of formal, cocktail and casual maternity wedding guest dresses up for grabs.

PinkBlush Maternity: PinkBlush Maternity is the place to shop for trendy maternity wear at affordable prices. We’re big fans of the brand’s lace maxi dresses that come in tons of vibrant colors. Better yet, this brand has a wonderful range of plus-size maternity dresses for wedding guests too.

If you find yourself in that quandary, you’ll be happy to know that Rent The Runway has a section devoted to designer maternity wear. With an unlimited subscription, you can browse endless options for formal maternity dresses, cocktail dresses and more by trimester, and select four items to start with and get unlimited swaps throughout the month.
