Floral prints may not be a usual go-to for fall (they’re more of a spring thing), a painterly, abstract take on the trend is a refreshing way to bring the essence of poppies and dahlias into the cooler months of the year. For an outdoor wedding, in a garden or at a winery, this sleeveless dress will fit right in.

The best thing about an LBD is that you can do so much with it. Want to layer a ton of jewels? No problem. Want to let your designer clutch or splashy new earrings be the star of the show? Easy. This one-shoulder formal dress is available in petite, standard, and plus sizes, so everyone gets to try it out. (Just note that the top tends to run small, per reviewers, so feel free to size up.)
