Deciphering wedding dress codes can feel like a full-time job. As a bridal stylist, I get questions about them all the time—and of all the instructions printed on wedding invitations, “casual” may be the most misleadingly simple. It rarely means the same thing as it does for a regular Saturday out, and the line between relaxed and underdressed is thinner than many guests realize.

Casual attire usually signals a daytime or more relaxed setting, like a backyard garden party, a seaside ceremony, or an intimate vineyard lunch. That doesn’t mean you can wear whatever you want, though. Denim, shorts, athleisure, head-to-toe sequins, formal gowns, and anything that looks like beachwear are all wrong here. Sneakers are generally off-limits too, as are white, ivory, and anything that could be mistaken for bridal (a rule at every wedding, of course, but worth repeating).

Still, your options are far from limited. Minis are perfectly appropriate as long as they’re polished; a shorter hemline in satin, cotton, or crepe feels celebratory, while a T-shirt dress does not. Modern slips and colorful dresses in flowing shapes are equally good choices, and when in doubt, a little black dress is a safe bet. For accessories, I recommend a low heel, simple sandal, or ballet flat to keep a dressier silhouette grounded; a small shoulder bag and understated jewelry can also dial the formality down a notch. But if you’re truly stuck, ask yourself: Would I wear this to an elegant dinner party? If the answer is yes, you’re on the right track.

Here, browse 24 dresses that strike the right balance, from party-ready minis to LBDs.

Mini Moments
The best mini dresses for casual weddings are elevated but not overly fancy. Kallmeyer’s Elaiza and Staud’s Freda are especially polished standouts, while Chloé’s ruffled number adds a bit of whimsy with a softer palette. Pair any of them with a kitten heel, and you’re set from the ceremony to last call.

– Banana Republic velvet mini dress, $180
– Chloé ruffled mini dress, $4,500
– Staud Freda dress, $595
– Simkhai Tali dress, $445
– A.L.C. Dion dress, $595

Slinky Slips
No surprise that the versatile slip dress works equally well for casual ceremonies—have fun with the streamlined silhouette by choosing one in a bold color. Veronica Beard’s lace-trimmed maxi and Isabel Marant’s tangerine midi are both great options. Just keep your styling simple—a minimalist heel, delicate jewelry, and a small clutch are enough.

– The Great. The Legacy dress, $495
– Veronica Beard Vernon dress, $798
– Stella McCartney lace-trimmed dress, $1,690
– Isabel Marant Nevana dress, $1,190
– Anine Bing Judy dress, $450
– Polo Ralph Lauren satin slip dress, $398

Vivid Hues
A bold palette can make even the simplest silhouette feel special, no embellishment needed. J.Crew’s Natasha short sleeve in deep ruby and Tory Burch’s flared midi in electric blue are prime examples, while COS’This drop-waist dress has a more subtle feel. For accessories, go all out with colorful, contrasting jewelry—or keep it simple with sleek silver pieces.

Classic LBDs
When the choices feel overwhelming, go for a little black dress (personally, this is my go-to for easy wedding guest outfits). Brandon Maxwell’s Sable mini is sleek enough for a late-night, intimate reception at the couple’s favorite restaurant. Khaite’s Scarla adds a bit more movement for a daytime party, and Dôen’s Rivelle is a romantic choice for a garden or vineyard wedding.
