26 Casual Wedding Guest Dresses for More Informal Nuptials

1. Lulus Forever Mesmerizing Scarf Dress

Best Scarf Dress

A fun mini dress is a great option for a casual event. This one has a bold pattern and a halter neckline, which is great for a summer wedding. The lightweight satin will keep you nice and cool, and you’ll definitely be able to wear this one again.

2. Crew Gwen Cupro Slip Dress

Best Pink Dress

Pink will always be a summer favorite, and if you’re into Barbiecore, you should totally consider this slip dress. The cupro material feels like silk (but is more durable and machine washable). We would pair this frock with a set of white heels for an ultimate summery color palette.

3. French Connection Whisper Light Sheath Dress

Best Square Neckline

This baby pink shade is undoubtedly going to highlight your summer glow, and the fitted waist and slightly A-line skirt will show off your curves. Contrast the minimalist aesthetic with your accessories—a show-stopping pair of heels and bold jewelry should do the trick.

4. Abercrombie & Fitch Trapeze Mini Dress

Best Trapeze Dress

If you’re looking for something comfortable, look no further. This flowy, mini silhouette has adjustable straps and is made of a lightweight cotton blend for those warm August and September days.

5. J.crew Tie-shoulder Dress

Best Floral Dress

Not only is this dress adorable for a spring or summer wedding, but it’s also made of a comfortable, breathable cotton. Wear your hair up to let the ruffles and ties around the neck be the stars of the show.

6. Lulus Sweet & Flirty Two-piece Dress

Best Two-Piece

A flowy two-piece set is a great pick for a backyard or barn wedding. The subtle sage color is flattering on all skin tones and we love the hint of midriff for a subtly sexy vibe.

7. Abercrombie & Fitch Asymmetrical Maxi Dress

Best Maxi Dress

You can’t go wrong with a basic maxi dress. The tiered sections will create the illusion of longer legs and are just so fun for twirling around in.

8. Lulus Super Sweet Mini Dress

Best Smocked Dress

Smocked dresses provide a comfortable, stretchy fit around the bodice, which is great for larger busts. This dusty rose color is also so feminine and lovely.

9. Reformation Catarina Dress

Best Babydoll Dress

Babydoll styles are all the rage right now (thanks, Bridgerton). Our favorite part of this dress? The adjustable tie straps. They connect at the top of the bodice on the back and add a long, dainty bow to each shoulder.

10. Zara Linen Blend Mini Halter Dress

Best for a Beach Wedding

Linen is obviously a summer favorite, and this dress would be a great choice for a beach wedding, where the stark blue will look beautiful in photos and the lightweight linen will keep you nice and cool.

11. Mango Linen Dress

Best Linen Dress

Made of 100 percent linen, this breezy dress is a wonderful choice for an outdoor wedding. The ring detail in the center is very ‘90s and if you couldn’t tell, we’re loving green at the moment. The sides also have small cut-outs to show a little extra skin.

12. Everlane The Seersucker Dress

We’ve never met a dress with pockets we didn’t like, and this seersucker option is no exception. The elbow-length sleeves make this one an excellent option as we head into fall, though it’s breathable enough to wear right this second.

13. Cece Tiered Baby Doll Dress

Best Ruffled Dress

Ruffles and florals are a feminine dynamic duo we always fall for. Pair this sweet mini dress with metallic heels for a wedding or with some white sneakers for a more casual look.

14. Zara Draped Dress

Best Shoulder Detailing

This sleeveless option features subtle shoulder pads for some extra volume and drama. The sleek silhouette has ruching on one side to emphasize the waist and this lime green would look gorgeous on so many skin tones.

15. Reformation Gavin Dress

Best for a Courthouse Wedding

From the high slit to the cap sleeves, this style has us totally captivated. Don’t be fooled by the high coverage on the front, because there’s a cute cutout on the lower back with a keyhole opening at the top.

16. Abercrombie & Fitch Cinch-front Dress

Best for a Summer Wedding

Between the light olive-green shade and the spaghetti straps, this one is our top pick for a casual summer wedding. The straps are adjustable and you can tighten or loosen the ties at the bust depending on your style.

17. Asos Curve Mini Sundress

Best LBD

You truly can’t go wrong with an LBD, and this flowy sundress is too cute to pass up. The sweetheart neckline is very flattering on small and large chests alike, and the straps are adjustable for a customizable length.

18. Asos Design Skater Sundress

Best for a Backyard Wedding

The fun print and frilly design of this mini dress make it a great option for a backyard wedding. It has a super casual yet cute aesthetic and gingham is one of our favorite summer patterns.

19. Majorelle Baker Mini Dress

Best Halter Dress

Nothing says summer casual like a halter mini dress—especially in a bright color like this yellow shade. This one has a tie-dye print and tassels at the ends of the halter ties.

20. Amanda Uprichard Adelene Midi Dress

Best Knee-Length Dress

We love the intricate print on this dress and the blue and white color palette. We’d add a pair of strappy white heels to elongate the legs and complement the white detailing in the dress.

21. Lilly Pulitzer Asteria Eyelet Minidress

Best Yellow Dress

If adorable is what you’re going for, this is the dress for you. We love the bright shade and the eyelet pattern. The neckline has a slight slit in the front and the straps can sit atop the shoulders or slightly off.

22. Asos Design Frill Neck Mini Dress

Best for a Fall Wedding

From the deep, cranberry red to the frilled long sleeves, this dress is a perfect fall wedding choice. The material is lightweight enough that you won’t overheat, and the decorative ruffles are a great detail if you don’t feel like wearing jewelry.

23. Steve Madden Citrus Dream Dress

Best for a Spring Wedding

This patterned midi has us wishing for springtime already. We love the blue, green and orange color palette and the bow tie straps. It’s 100 percent cotton, so you won’t feel like you’re overheating.

24. Saylor Joanie Dress

Best Tiered Dress

This funky design has metallic threading throughout for an unexpected pop. The straps are also adjustable, so you’ll have no issue customizing their length to your liking.

25. Lulus Shift And Shout Dress

Best Shift Dress

You’ll have so much fun accessorizing this basic mini with a bold pair of heels and statement jewelry. We also love the added interest of the contrasting zipper down the back.

26. Bp Easy Crewneck Sweater Dress

Best for a Winter Wedding

A casual winter wedding calls for a chic sweater dress. Swap out the combat boots above for a sleek over-the-knee pair to dress things up. One thing to note: Customers say it runs a smidge big, so you may want to size down if you’re looking for a more fitted silhouette.
