Whether it’s your first baby on the way or you are expecting a third child, maternity style always manages to feel slightly complicated when it comes to formal events. Regardless of how cute a baby bump can look all dressed up, finding a fun frock that manages to toe the line between stylish and comfortable is often a challenging quest—but it doesn’t have to be! For insight on finding the perfect formal maternity dress for you, we consulted Tiffany London, the founder of Tiffany Rose Maternity.
"It is absolutely possible to fuse comfort with style, elegance, and glamour–so pregnant wedding guests should look equally as stunning and stylish no matter what stage of pregnancy," she says. London recommends empire waist silhouettes, as it's both flattering and comfortable for your bump. You'll also want to consider the formality, venue, and season of the nuptials to find an outfit that's appropriate for the specific event. The most important thing, however, is that you feel confident, comfortable, and beautiful in whatever you choose.
To help you narrow down your search for maternity guest dresses, we've researched and rounded up the best options with these features in mind. For a formal black-tie affair, we love the Kim and Kai Abigail Off-the-Shoulder Maternity Dress and the Seraphine Maternity Gown With Neckline Tie. Looking for a gorgeous floral frock? You can't go wrong with the River Island Maternity Floral Wrap Dress.

What to Look For in a Maternity Wedding Guest Dress
Comfort and Fabric
There's no need to sacrifice style for comfort when it comes to maternity wedding guest dresses. In fact, there are scores of styles out there that are not only bump-friendly but fashion-forward, too.
"I think everything you would look for in a beautiful dress should stand regardless of whether you’re pregnant or not–today you should not have to compromise one jot," says London. "Of course, I would always say that comfort is paramount and that’s why we make it a huge focus on our own design process at Tiffany Rose."
When shopping for a maternity wedding guest dress, keep in mind that the fabric will play a big role in the overall comfort and fit of the garment. Dresses made of stretch cotton, lace, jersey, and stretch crepe are much more breathable than other fabrics while styles with elastic, adjustable, or no waist require little or no adjustments. Additionally, dresses designed with a stretch lining also make for a relaxed and flattering option that doesn't require too many alterations.
"We would always recommend an empire line silhouette when choosing your perfect maternity occasion dress–simply because it’s the most flattering fit when you’re dressing a bump and so is a great place to start," London recommends. "It also opens up your options in terms of fabrics–like a silk satin floaty design or a figure-hugging jersey style. Either way, get the fit right around your new waist and growing bust, and the rest will follow!"
What are the most maternity-friendly dress silhouettes?
Some universally flattering and bump-friendly silhouettes are empire waist dresses, wrap dresses, muumuus, A-line, and body-skimming dresses. However, finding the right maternity dress is all about choosing a silhouette that flatters your body type and makes you look and feel your best.
What dress fabrics are the most comfortable for pregnant wedding guests?
"The comfiest fabrics are those with soft stretch and are also breathable," says London. "The stretch makes it kinder and softer on your growing curves so they can be accommodated without restriction. During pregnancy, your temperature can fluctuate with many women claiming they feel warmer than usual, so it’s beneficial that any figure-hugging styles are made with breathable fabrics like a viscose/elastane blend."
Can I wear a non-maternity guest dress?
"It is completely fine to choose a non-maternity dress, but word of warning, it can sometimes be more trouble than it’s worth–so you just need to be prepared for that," London advises. "My advice would be that if you want to be the best-dressed guest, choose a style that has been specially designed for pregnancy by a reputable brand/designer. Otherwise, you will run into fit problems further down the line, and then the dress will be wearing you, not the other way around."
She continues, "it’s easy to forget that it’s not just your bump that will grow, your bust size will increase and your rib cage will expand–there’s a lot of subtle changes going on every day!"
