17 Best Plus-Size Wedding Guest Dresses to Wear This Season

We've named Reformation dresses best overall in previous wedding guest outfit roundups, and this gorgeous fitted silk gown is no exception. A light green and cream floral combo makes it ideal for a full-length outdoor wedding dress, and the high-neck halter neckline is simply perfection. It's lightweight for breathability and can be worn with a strapless bra. While it has a higher price tag, Reformation is known for its sustainable approach to fashion so you will both look and feel good in this dress.

Torrid makes clothing for curvy bodies and offers sizes 10 through 30. We love this babydoll silhouette, and so do customers as this dress has a 4.5-star rating online and close to three dozen customer reviews. The textured fabric is super cute while the v-shaped neckline, slight balloon sleeves and cinched waist elevate the look. It's also a total steal and could be worn to work events or other intimate gatherings, making it that much more of a great value to your closet.

At just under $60, this full-length V-neck pleated evening gown is available in over 12 colors. Made of non-stretch material, this style runs slightly small so Amazon reviewers say it's best to go up one size. It is, however, fully lined and has a zipper in the back, although it lacks padding in the bust area. Still, five-star reviews call it an "amazing dress" with one writing, "I bought this dress to wear to a special event. I sized up because that’s what I read in the reviews. The dress is beautiful, well done and comfortable."

This showstopper has detailed embellishments on the front and back so you can shine and sparkle from every direction. The tulle bottom adds an elegant touch and allows for movement for when you hit the dance floor with friends and family. It has an almost perfect five-star rating online and while multiple five-star reviews call it a beautiful dress, some note that the length can run long.

Bring this bright two-tone maxi dress out of the closet for your next beach or garden wedding. The pleats add a fun touch and the asymmetrical hem will make this look extra fun to twirl and twist in all night long. It has moderate stretch, per ASOS's product description, which adds to the comfort factor. It's easy, breezy beach vibes all day long with this dress.

Show a little shoulder with this black evening dress. The shoulder cutouts make it more stylish than your average LBD, and the high slit adds subtle sex appeal. It's available in eight different colors, including embellished wine and glitter finishes. A 4.3-star Amazon rating and glowing customer reviews mean you'll likely also love the dress. One customer who wore the gown to her son's wedding writes, "Plus-size formals can be so matronly looking and I am far from matronly! The dress was stunning and I had compliments all night long!"

Lane Bryant is a woman-founded brand built on a can-do attitude that applies its philosophy to its fit and fashion. This jumpsuit is actually named after the brand's founder, pioneer Lena Bryant, and gives off the same energy which the clothing brand was founded on. It's the perfect one-piece outfit, thanks to a wide pant leg, self-tie belt and short sleeves. Pair with a bold necklace and strappy heels to dress it up or slip on a pair of espadrilles and a floppy hat if it's a more casual wedding.

Vintage-themed wedding on your horizon? Say hello to your new favorite dress that will take you back in time with a classic sweetheart neckline and adorable cap sleeves. It has a flattering fit-and-flare silhouette and a buttoned bodice for that extra chic touch. The fabric combo is designed to have some stretch to it. Customers say it fits like a "forgiving glove." While you may not pair the dress with gloves (although it does give that vibe), we think the four out of 5-star rating means you will agree with the rave reviews.

You can go all out formal and still stick to a budget thanks to this full-length gown by Dia&Co. Beautiful woven chiffon and a detailed, beaded belt make it perfect for formal events like weddings and proms. The long sleeves will flutter in the evening wind while keeping you warmer than a sleeveless gown. Choose from eight colors, whether you want burgundy for a fall wedding or light pink for a spring ceremony.

You may be surprised to learn that Amazon has a good selection of plus-size dresses that can certainly function for a wedding. Although this maxi dress is a bit more informal, we think it makes the perfect fit for a backyard wedding (and all future summer activities). The dress has a 4.3-star rating on Amazon and over 8.4K customer reviews with multiple five-star reviews noting how flattering and pretty the dress is. We appreciate the variety of colors and patterns available, as well as the soft and smooth material that will feel comfortable while you are sitting in (let's be honest) a not-so-comfortable chair.

Sizes: 1X-6X | Colors: Black (pictured), burgundy, navy, dark yellow, peach, light olive, jade green, charcoal feather, black confetti print, blue ditsy floral, brown floral, green floral, black confetti, black/dark camel, green vine/leaf, navy/pink abstract, rust orange, blue, bright pink, navy abstract, red/white ditsy floral | Material: Rayon, elastane

Lightweight woven chiffon, flutter sleeves and a high fitted empire waist make this dress look a lot more expensive than $100 but in fact it is under that price point! Over 200 online customer reviews rave about the color and quality of the dress, saying that you won't have any issues with it being see-through. One customer does note that the hidden back zipper kept getting stuck, though. Still, the fitted floor-length dress can be worn to a fancier destination wedding while saving you money for those tickets to the ceremony and reception. We do wish the burgundy color was available in plus sizes too.

Sizes: 1X-3X | Colors: Sage brush (pictured) | Material: Polyester

This one-shoulder dress has a "perennial silhouette," per the brand's description, and we have to agree with this distinction. The deep red color fits the color palette for any season and the midi length combined with short sleeves mean you can stay relatively cool at a warmer ceremony or layer with tights at a winter wedding. It's made from stretchy polyester and spandex, and is fitted through the bust, waist and hips for a flattering fit. Pair with your favorite pair of heels and you can even repurpose this dress for work.

Whether you're attending a summer wedding when the sun will be beating down on you during the ceremony or you just prefer mini to full-length dresses, consider this babydoll number with puff sleeves that gather at the bottom and a square neckline. The skirt will blow in the wind and you will shine bright like a gem (hence the name). Keep in mind the manufacturer recommends you hand wash the dress.

The cut-outs on this citron yellow dress make it perfect for a spring or summer wedding fit. Bubble blouson sleeves and a front tie will help you subtly stand out among guests without diverting too much attention from the bride, of course. You can wear it with or without a bra, per the manufacturer, and one customer who wore it to a black-tie, Southern wedding says, "it was so incredibly comfortable, I didn't have to wear any tight fitting undergarment since the sewn in slip was perfect coverage." We only wish it came in more colors.

We have included Spanx's products in previous roundups for its flattering tummy-smoothing shape-wear, bathing suits and more. Thick ponte fabric is designed to have a smoothing effect, making it a great option if you want to slim your tummy area. One five star review says, "The fabric has a Spanx feel of holding but not squeezing." The simple silhouette is versatile for all evening gatherings, whether that be a city wedding reception or happy hour with friends. We appreciate the wide shoulder straps that can hide bra straps and that the dress is machine washable for easy cleaning.

Sizes: 1X-3X | Colors: Classic black (pictured), true red | Material: Premium ponte fabric

If you haven't already heard of Rent the Runway, let us introduce you to your one-way ticket to a designer wardrobe on a budget. Shop à la carte for a singular look or subscribe to one of its plans and receive five items at various intervals each month. We love how the website has a wedding-specific category that makes scrolling through its vast inventory a little less intimidating. This bright mid-length dress with spaghetti straps and side slits is made for a summertime wedding on a rooftop bar. If you decide not to sign up for a plan (which can range between $69 and $149 per month), you can get this dress as a one-time rental for as low as $30 or buy it for $306.
