There are a dozen reasons you might choose a plus-size pant suit for a wedding: Maybe you're not keen on wearing dresses for wedding guests, or want something warmer, or simply want to change up your look in the thick of wedding season. Whatever the reason, a dressy pant suit is a fun alternative—but it can't be just any pant suit. To elevate the ensemble for weddings, look for unique elements and design details that set the suit apart from workplace attire: A bold pattern or print, jewelry-inspired detailing, even the ability to go shirtless underneath the blazer. (And don't limit your search to the classic blazer-and-trousers combination; wedding guest jumpsuits, vest-and-pant separates and coordinating sets are all chic options that meld comfort and fit with sophisticated style.) Finally, don't forget to accessorize. Adding a color-pop shoe, statement earrings or a cool clutch can propel the most simple suiting into the wedding-guest-fashion stratosphere.

The Best Plus-Size Pantsuits for Wedding Guests

Not all plus-size wedding pant suits are created equally, and that's a good thing. Shop for suits made from different fabrics and featuring different design elements and silhouettes to find the one that best fits the wedding dress code—think linen separates for beach weddings, a tuxedo for black tie affairs and so on. There are lots of places to buy women's pant suits, so the options are endless. This selection (from a variety of retailers and featuring pieces available in sizes 16-30) has something for every type of "I do."

Tahari ASL Crepe Blazer & Wide-Leg Pants

This chic Tahari suit comes in two fun hues: dreamy pastel Pink Macaroon and bold, vibrant Cobalt. Try the former for a springtime garden wedding and the latter for evening or nightclub-inspired events. Either way, pair it with a fun printed blouse and bold jewelry to elevate the look from business to party. Note that the brand recommends sizing down if you're between sizes or, better yet, stopping by in person to try it on.

Size Range: 14W-24W

Adrianna Papell Plus-Size Flutter One-Shoulder Jumpsuit

Bridging the gap between a dress and pants, this wide-leg jumpsuit makes a fantastic plus-size pant suit for wedding guests. (Psst, brides! It also comes in white—we love it for a chic rehearsal dinner or welcome party look.) It's made with 5% elastane, and on the brand's stretch scale it falls right in the middle, meaning there's a little, but not a lot, of give. Try two sizes if you aren't sure—you'll want room to dance!

Size Range: 14-28

Nina Parker Satin Blazer & Pants

Macy's plus-size pant suits for weddings are hot commodities, and it's easy to see why; this Nina Parker suit is oh-so-party-ready in hot pink satin. Go fully monochromatic with a hot pink tank underneath and accessorize with chunky gold jewelry—then mix and match the separate pieces into your wardrobe for everything from work to girls' night out.

Size Range: 0X-3X (blazer) and 14W-28W (pants)

AW Bridal Lorraine Jumpsuit in Verdant Wilds

Ruched crisscross halter, wide-leg pants and pretty, wedding-ready pattern: This jumpsuit has it all. But the main reason it makes our list is for the inclusive sizing options. Available up to size 30 in ready-to-wear, it's also fully customizable: Shoppers can input their exact measurements and choose the length (and even add pockets!), so the final result fits like a glove.

Size Range: 0-30 (with additional custom sizing options)

FashionNova Pretty in Pink Embroidered Blazer Set

It's essential that plus-size pant suits for weddings stand out from the sea of workplace pantsuits, and this one does just that with a unique embroidered floral pattern set against high-shine fuchsia. Wear the blazer buttoned with nothing underneath, and add an understated necklace (or three). Of note: The suit has rave reviews, but some commenters noted that it runs small or lacks stretch; they recommend sizing up if you're in between.

Size Range: XS-3X

SuitShop Women's Tuxedo in Navy

Women's tuxedos are having a moment, and we love the look for black-tie weddings. SuitShop does them best, and this chic tux comes in black, white or unique navy. (With varying lengths on offer, this is also available as a petite plus-size pant suit for weddings.) Go bold with accessories against the solid canvas: Layer on the gold, silver and diamonds, or add a pop-of-color heel or earrings. Pieces can be shopped separately, but at $224 for the set, the price is right.

Size Range: 00-28 (short, regular and long)

Spanx Carefree Crepe Wrap Blazer & Trousers in Midnight Olive

When it comes to fit and comfort, nobody does it like Spanx. This belted blazer has a relaxed fit with a wrap front to define the waist. Try the coordinating trousers or, for tropical destination weddings, opt for the shorts version and pair the look with metallic lace-up heels and a high party pony.

Size Range: XS-3X (petite, regular and tall)

Lane Bryant Perfect Drape Belted Blazer & Pants in Fiery Red

It's getting hot, hot, hot! Or at least, that's what the hue of this fiery plus-size pant suit for a wedding implies. The blazer is sophisticated with a double-breasted button option, but let it drape and use the wrap tie for a more relaxed and fashion-forward wedding look.

Size Range: 12-28 (regular and petite)

Eloquii Wide Leg Printed Pants & Shoulder Tie Crop Top

We love a bold pattern for destination wedding guest dressing, and these tropical-inspired separates are a unique take on plus-size pants suits for weddings. The wide-leg pants have elastic at the back waist, and the crop top has elastic at the hem, so everything stays put and your look stays put together; pair it with wooden bangles and a blocky wedge or espadrille.

Size Range: 14-32

Lala Satin Playsuit in Wild Woman

Are you a fashion girlie who likes to stand out? Women's plus-size pant suits for weddings—or playsuits like this one, rather—will do just that. From the funky tigers-on-teal print to the extra-long shirt and side-slit pants, this look is full of unique elements that make a statement. It's intentionally oversized, so order based on your usual pants size.

Size Range: XS-3X

Marina Rinaldi Double-Breasted Cady Jacket & Palazzo Pants

Trend alert: This perfectly subdued minty sage hue is in—and we're here for it, especially for spring and fall weddings. The jacket is a splurge, but the quality backs it up: Crafted in Italy, it features hand-sewn pick stitching around the lapel and a comfortable, luxurious cady crepe material. Post-wedding, it can be styled every which way and worn again and again.

Size Range: 12W-22W (jacket); 12W-18W (pants)

Eloquii Pinstripe Blazer & Culottes

Who says plus-size pant suits for a wedding have to be regular pants? This seaside-wedding-ready pinstriped blazer is paired with culottes instead (culottes are trousers that hit just below the knee and are extra wide-legged, to almost appear like a skirt). Pair this with white or blue statement sandals.

Size Range: 14-32

Karen Millen Tailored Denim Look Linen Pants & Blazer

With this chic linen plus-size pantsuit for a wedding, you have two options: Lean into the denim look of the heather blue hue for a Western wedding—we're thinking cowboy boots and lots and lots of cool jewelry—or dress it way up with heeled sandals, bare chest and statement earrings.

Size Range: 14-20 (XL-2XL)

June + Vie Wide-Leg Plisse Jumpsuit

A micro-pleated plisse fabrication dresses up this plus-size pant suit for wedding guests, which comes in two vibrant shades: Dark Sapphire and Vivid Pink. The jumpsuit can be worn loose or cinched at the waist with a removable self-tie belt, and the flutter sleeves and V-neck are flattering details.

Size Range: 10/12-30/32

ASOS Luxe Curve Tailored Suit in Floral Print

Italy is calling! We're obsessed with this limoncello-inspired pant suit: The buttery base color is super on-trend, and the monochromatic watercolor florals add a pop of interest. The fabric is softer and flowier than it looks at first glance, making it comfortable even in warm climates. Pair it with gold jewelry and open-toe sandals.

Size Range: 14-26

Wildfang The Empower High-Waisted V-Neck Jumpsuit

The name says it all: This jumpsuit is like a classic power suit, deconstructed and put back together. The high-waisted pants are wide-leg and roomy, while the attached vest is tailored and fitted. A high-neck collar tops the V-neck and can be worn buttoned or unbuttoned to showcase a necklace. We love this look as an ultra-modern take on traditional suiting.

Size Range: 0-26W

SuitShop Women's Tan Suit Jacket & Pants

A classic neutral is a pretty and polished color choice, especially for fall and winter weddings. This one features a tailored design and an Eco Stretch fabric that allows for movement and comfort. Dress it up with jewel tones (we love a silk scarf with this) and an ankle-height bootie.

Size Range: 00-28 (short, regular or long)

DB Studio Allover Sequin V-Neck Tank Jumpsuit

For evening weddings, we love a little sparkle. This deep, deep green jumpsuit is covered all over with clear sequins to catch the light and shimmer on the dance floor. Its part-spandex fabric composition allows a little stretch, and the pants fall at just the right length to show off a pretty heel.

Size Range: 2-24

Eileen Fisher Linen Vest & Wide-Leg Pants

Pantsuits don't exactly scream "beach wedding," but this Eileen Fisher vest-and-pant combo might just be the exception. Its sandy linen fabric is breathable and perfect for daytime affairs, and the silhouette is on trend. Elevate the look with fine jewelry and a pretty heeled sandal.

Size Range: XXS-3XL

Le Suit Crepe Two-Button Blazer Pant Suit in Celeste Blue

This blue-hued suit is perfect for summer and fall weddings, and the pieces are great for mixing and matching post-wedding. The tailored crepe ensemble actually comes in a variety of jewel tones, though: Try mixing the top and bottom for a fresh, color-blocked look.

Size Range: 14W-24W

Marina Rinaldi Silk Satin Shirt & Trousers

An Italian brand under the Max Mara umbrella, Marina Rinaldi is a go-to for splurge–worthy pant suit separates—and the quality to back up the prices. This silk satin shirt-and-trousers set is stunning and unique in a fuchsia fading-rose print, and the loose, oversized fit is both on-trend and ultra comfortable.

Size Range: IT 15-33 N (US 6-24)

June + Vie Smocked Jumpsuit in Floral Safari

Chinoiserie is trending in wedding decor—so why not in guest attire, too? This plus-size wedding guest jumpsuit brings the pattern to life, with a ruched bodice and halter neck. The long sleeves can be worn off the shoulder or pulled up to create a cool square neckline.

Size Range: 10/12-30/32

Tahari ASL Faux Double Breasted Blazer & Pants in Grenadine

Unique detailing is always a plus for wedding-ready pantsuits. This blazer has double rows of shiny gold buttons and a fun red-orange hue that's great for summer weddings. Wear it with matching trousers for a vibrant monochromatic look, and rewear the jacket again and again over dresses to future weddings.

Size Range: 14W-24W

Jessica London 2-Piece Linen Capri Set

Headed to a beach destination wedding? This lightweight linen set features a sleeveless tunic top and capri pants—ideal for a casual event. It's available in five colors, but our favorite is the gorgeous blue-green.

Size Range: 12-28
