32 Bump-Friendly Wedding Guest Dresses That'll Have You Feeling Fresh, Not Frumpy

Maternity wedding guest dresses require a level of functionality and comfort that you may not otherwise be looking for. And, on top of those considerations, you'll also want to feel pretty and confident, maybe more so than ever. Truthfully, we'll be the first to admit that figuring out what to wear to a wedding—or any fancy event, for that matter—while pregnant is not easy.

As with selecting a wedding guest dress any other time, you'll need to consider the wedding dress code and seasonality first (if you're a fashion-forward dresser, you may also want to consider wedding guest dress trends). Then, you want to think about practicality. Can you easily get in and out of the dress for frequent bathroom breaks? Will it feel comfortable after spending all day (and night) in it? Can you dance?

So if you've been having a hard time getting out of a pregnancy-induced frumpy era, it's time to buy a 'fit from Tuckernuck.

Thankfully, Lulus is an economical option. Plus, we have an exclusive code you can use for even more savings. Use code THEKNOT30 for 30% off (new customers only; select categories; terms apply; US only).

Hatch: Hatch is a popular maternity retailer and the brand has a selection of dresses that are perfect for a wedding. So if you're already doing a big haul from here, add a few dresses to your cart for upcoming weddings.

Club L London: "If the dress code reads cocktail attire, head straight to Club L London," Garvey says. "The brand offers figure-hugging maternity dresses perfect for glamorous moms-to-be." Its gowns come in various fabrics, silhouettes and colors, with plus and petite sizes available, too.

Jenny Yoo: For black-tie attire, the bridal and bridesmaid designer offers maternity takes on some of her most popular dresses. They're crafted in the same high-quality fabrics she uses for her non-maternity styles and are on the pricier end for maternity wear—but for formal or black-tie events, it doesn't get better.

Hill House Home: When you're pregnant, few things sound better than taking a nap. And while it might not be quite appropriate to sleep at someone's wedding, wearing one of Hill House Home's iconic Nap Dresses is a good consolation prize. As the name suggests, they are ultra-comfortable and feel like you're cuddled up for a quick snooze.

How to Choose a Maternity Dress for a Wedding Guest

It can be difficult enough figuring out what to wear to a wedding even when you aren't pregnant. What does the dress code mean? Will I be cold? What's the most comfortable footwear? Add in working around an ever-growing bump, and dressing up gets even more difficult. Here, Garvey makes it easier by offering a few key tips.

Look for bump-friendly silhouettes. "There are no rules for pregnancy fashion, but certain silhouettes do tend to work well," Garvey says. "An empire-waist dress is cinched under the bust and has a free-flowing skirt that allows plenty of room for a baby bump. With a wrap dress, you can adjust the fit for added comfort."

Consider fabric. "In terms of fabric, opt for something soft and breathable," Garvey adds. "Natural materials like silk, cotton and linen work well for spring and summer weddings. For winter celebrations, bring extra layers to keep you warm. Your skin may be more sensitive than usual, so avoid anything with itchy tags or scratchy fabric."

Pair your look with comfortable shoes. Garvey's top tip for attending a wedding while pregnant? Wear sensible wedding guest shoes. "Swollen feet and ankles are common side effects of pregnancy, and uncomfortable footwear may aggravate the symptoms," she says. "So ditch the high heels in favor of comfortable flats like this pair from Birdies."

Photo: Jenny Yoo

It can be hard to feel like yourself when you're pregnant, but nothing quite ups the confidence like putting on a black-tie gown. For something as formal as black-tie, opt for high-quality fabrics like this satin back crepe and look for a dress that's specifically made for maternity rather than sizing up in regular clothing. Jenny Yoo has some stellar options: This maternity wedding guest dress is a favorite, especially in rich jewel tones like hibiscus and emerald.

Hill House Home's cult-favorite nap dress is the perfect maternity wedding attire (though the original style is already bump-friendly, the brand does offer a specific maternity version).

The trending style is actually perfectly on point for pregnant bellies, so this maternity dress for weddings says you haven't given up on fashion.

This isn't the classic "florals for spring" print—instead of watercolor hues, it's rendered in a chic and sophisticated deep red and cream palette. An asymmetrical hemline mirrors the single shoulder and allover draping is both flattering and elevated.

Size range: 4–12

17. Best Non-Maternity Maternity Wedding Guest Dress: Pomander Place Hot Pink Soleil Gown

Photo: Tuckernuck

Quite a few non-maternity styles made our list here, and this style takes the cake thanks to its expansive size range and loose-fitting silhouette. Plus, it's beautifully wedding-ready with an interesting asymmetrical detail and side slit for ease of movement.

20. Best Short Maternity Wedding Guest Dress: H&M Mama Sequined Dress with Low-Cut Back

Photo: H&M

Short dresses for weddings ride a fine line of appropriateness, pregnant or not. If you're going the mini route, make sure other areas are covered—such as with long sleeves, like in this sequined design—and the overall vibe is still formal. We love this for a New Year's Eve wedding with sheer black maternity tights.

Size range: XS–XXL

If you aren't quite ready to announce your pregnancy (or want to wait so you don't steal the couple's moment), look for a loose-fitting but stylish style that will disguise the bump. Reformation's Maribelle Dress is a good example with a fitted bodice and full skirt.

Shirtdresses can sometimes read too casual for weddings—but splash them with a bold print and the look is instantly dressier. This one's exotic print and mid-length sleeves make it a perfect pick for fall weddings; pair it with heeled boots and gold jewelry. (Pss: Note that H&M's Mama collection is only available online.)

Size range: XS–XXL
