Don’t get us wrong, we love celebrating the love between two people we’re close with. But with the number of weddings we’ve RSVP’d to this year, we’re ready for a break from buying fancy dresses repeatedly. Anytime we get the chance to shop for casual wedding guest dresses is exciting, because we know we will get to wear them way more than just for that one night.

If you aren’t sure where to start, we recommend reflecting on what your personal style is—do you prefer fitted silhouettes or A-line; do you like neutral colors or perhaps a pattern; are you a fan of long hems or short ones? This will help you narrow down what dresses you’ll feel most comfortable in. After all, the goal is to be able to wear these pieces over again, so you might want to steer clear of something too far out of your comfort zone. Here, 26 casual wedding guest dresses for you to shop right now.

6 Fashion Trends We’re Ready to Say Goodbye to For Fall

lulus scarf dress

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.

Size range: XS to XL

jcrew pink dress

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.

Size range: 00 to 24

french connection

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.

Size range: 0 to 12

abercrombie and fitch trapeze dress
Abercrombie & Fitch

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.

Size range: XXS to XL

jcrew floral

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.

Size range: XXS to 2X

lulus two piece

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.

Size range: XS to XL

abercrombie and fitch blue dress
Abercrombie & Fitch

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.

Size range: XXS to XXL

lulus mauve

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.

Size ranges: XS to XL

reformation green dress
The Reformation

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.

Size range: 0 to 12

zara linen

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.

Size range: XS to L


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.

Size range: 0 to 12


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.

Size range: XXS to XL


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.

Size range: XXS to XXL

zara green

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.

Size range: XS to XXL

reformation blue dress

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.

Size range: 0 to 12

abercrombie and fitch green
Abercrombie & Fitch

16. Abercrombie & Fitch Cinch-front Dress

Best for a Summer Wedding

Size range: XXS to XL

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.

Size range: 12 to 26

asos gingham1

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.

Size range: 0 to 14


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.

Size range: XXS to XL

amanda uprichard

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.

Size range: XXS to XL

lilly pulitzer
Saks Fifth Avenue

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.

Size range: 00 to 16

asos winter dress

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.

Size range: 0 to 14

revolve steve madden

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.

Size range: XS to XL

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.

Size range: XS to XL
