Why Fall Is the Best Season for Plus Size Wedding Guest Fashion
Fall gives us more to work with than any other season—layering, deeper colors, textured fabrics, and comfort-focused pieces are in, and they naturally work well with plus size fashion. As someone who lives in chunky cardigans, midi skirts, and flowy pants all fall long, I can personally say it’s the easiest time to combine style and comfort.
Another perk? You’re less likely to worry about sweating through your dress or slipping in stilettos on dewy summer grass. Fall gives you permission to rock boots, layers, and cozy chic with full confidence.
10 Show-Stopping Fall Wedding Outfit Guest Plus Size Casual Picks
1. Luxe Lace Dresses
There’s something timeless and romantic about lace, especially in autumn tones like burgundy, forest green, or navy. Lace dresses are perfect for plus size figures because they often come with lining that creates structure while still showing off a touch of skin. They’re great for semi formal or slightly dressy casual weddings.
Style Tip: Add a nude block heel and a soft shawl to stay warm during an outdoor October ceremony.
2. Classy Wide-Leg Pants Ensemble
Wide-leg pants are one of my favorite outfit staples, especially in the fall. They flatter curvy figures by elongating the legs and balancing out proportions. Pair them with a satin blouse or structured peplum top for a classy yet casual vibe.
Perfect For: Semi formal or outdoor weddings that call for comfort without sacrificing polish.
3. Boho Maxi Skirt & Sweater Combo
This look is as comfy as it gets but can be styled up with accessories. Choose a flowy printed maxi skirt and pair it with a cropped knit sweater tucked in just right. It's ideal for rustic weddings or venues like barns and vineyards.
Why I Love It: It’s warm, comfortable, and lets you move and dance freely. Plus, it’s easy to rewear for brunch or date night!
4. Effortless Wrap Dress
The wrap dress has been a plus size holy grail for decades, and for good reason—it accentuates the waist, flatters the bust, and creates an elegant silhouette. Look for one in fall floral prints or jewel tones.
Bonus: You can easily dress it up or down with heels, booties, or even a leather jacket if it’s chilly.
5. Elevated Jeans Look
You might think jeans at a wedding? But hear me out. For a casual fall wedding, especially something outdoors or intimate, dark-wash jeans paired with a silky blouse and blazer can look super chic. I’ve seen this look pulled off with confidence and elegance—just keep your denim clean, dark, and structured.
Style Hack: Add heeled booties and statement earrings for an instant glow-up.
Amazon Product Recommendation #1 Levi's Women’s Classic Straight Jeans
These jeans are the perfect balance of structure and stretch. Designed for curvy bodies, they contour without feeling tight and are a great base for elevated casual wedding looks.
Add these to your wardrobe if you need jeans that are dressy enough for a wedding but comfortable enough for dancing all night.
6. Chic Romper with a Longline Duster
Yes, plus size women can absolutely rock a romper! Look for styles with flowy sleeves and a cinched waist. A rich fall hue like mustard or wine works beautifully in October. Layer with a longline duster or cardigan for extra warmth and dimension.
Style Note: Add a belt and heeled mules to elongate the legs and define your waist.
7. Tunic Top & Leggings Combo
If you're heading to a super casual fall wedding—think backyard or forest setting—a long tunic top with luxe leggings can be surprisingly elegant. Choose fabrics that elevate the look: think faux leather leggings or velvet tunics.
Why It Works: You’ll feel like you're in pajamas but look completely wedding-ready.
Amazon Product Recommendation #2 Popana Made in USA Women’s Plus Size Jersey Long-Sleeve Tunic
Soft, stretchy, and flattering for all shapes, this tunic is long enough to wear with leggings and stylish enough to be dressed up with a chunky necklace and boots.
Grab this if you want an effortless look that transitions from ceremony to reception without fuss.
8. Statement Jumpsuit
For the modern woman who wants to stand out, a jumpsuit is a chic and unexpected choice. Look for one with wide legs, a wrap top, or ruffled sleeves. This look is ideal for a semi formal or evening wedding where you want to bring the drama in the best way.
Pro Tip: Navy, hunter green, and terracotta are fall-friendly colors that also photograph beautifully.
9. Slip Dress + Cardigan Layer
Turn your summer slip dress into a fall-ready outfit by layering a chunky knit cardigan or even a blazer over it. This combination is fashion-forward and cozy. Add some tights and booties if the temperature dips.
Ideal For: Transitional weather in October and layered looks that still feel dressy.
Amazon Product Recommendation #3 ANRABESS Women’s Knit Open Front Cardigan Plus Size
This best-selling Amazon cardigan is buttery soft, lightweight yet warm, and drapes beautifully over dresses and jumpsuits.
It’s the perfect layering piece to keep in your closet for weddings, work, or just running errands in style.
10. Vintage-Inspired Midi Skirt & Blouse
There’s something incredibly elegant about a pleated midi skirt paired with a satin or high-neck blouse. You’ll look like you stepped out of an old movie—refined, graceful, and effortlessly stylish.
