Bodycon, but make it totally wedding-appropriate. This floral column dress would be so cute with strappy heels and a statement bag.
A black-and-white polka dot print is the easiest way to spice up a basic black dress without going full maximalist. Plus, the cowl maxi silhouette never goes out of style.
