The Alejandra dress from Petal & Pup comes in three colorways — navy, tan, and emerald—all of which would look stunning against an autumnal backdrop. Details worth highlighting include the midi frock’s cowl neckline and subtle-yet-sexy slit up the left thigh. Dancing across the fall-colored base hue is a floral pattern (florals for fall? absolutely), and the piece boasts a satin sheen finish. We especially love this option for mid- to late-September nuptials, when the chill of autumn hasn’t completely overtaken the weather forecast, but you can easily pair the dress with a long coat or cape in brisk temperatures.

For a more low-key affair, this airy bohemian maxi with long sleeves wouldn't look out of place at a rustic farm wedding in October.

Reformation is a favorite destination for wedding-goers for good reason. Boasting a wide range of flattering, on-trend styles and sizes, there's something to suit everyone. We love this sweetheart-neckline midi dress that flares and flatters from the waist down in the perfect fall floral.

Whether the nuptials you’re attending are cocktail or black-tie, this gown will be appropriate for both dress codes. The floor-length silhouette has a slit that starts at the knee, and the dress’s material cascades down the leg with ruffles, giving the skirt more bend and body. And while body-hugging, the body-con garment is made from a blend of polyester and spandex, so it’s comfortable and easy to move around in. What’s more, the dress comes in nine colors, from burgundy to royal blue, so you’re almost guaranteed to find a shade that matches your personal style.

Another option for anyone looking for a fall wedding-guest dress that can be worn again and again is this number from Good American. Good American's sleeveless turtleneck midi is the perfect example of a done-in-one ensemble that can be dressed up or down. Elements like footwear, jewelry, and outerwear will be key to bringing out the dress’s formal side. But even with minimal embellishments, the body-hugging garment is going to make a statement, for no reason other than its sculpting fabric instills a sense of confidence in the wearer. Plus, with the right layering tactics, the turtleneck design can take you into the colder months as well.

Feather accents are seeing a renaissance this season, and the Aurora dress by LPA displays the detail in a tasteful fashion. Consider the garment an LBD with a twist; a neckline that’s flirty and fluffy. Incorporate a pop of color with vibrant or metallic heels, or opt to go classic and monochrome with a chic black pump.
