The locale: a black-tie bash on a boat
The dress: empire-waist dress with lace-embellished neckline and hem and rhinestone-adorned straps and cap sleeves. eDressMe, $398.
Why it works: "This evening dress has just the right mix of formal and festive touches that make it an ideal choice for nautical nuptials," says eDressMe's founder and style expert Joanne Stoner. "The full, flowing skirt gives it a free, whimsical spirit that is consistent with an outside on-the-water affair. The skirt also camouflages any extra tummy weight, and the cap sleeves cover the part of the arms that some mothers-of-the-bride want to hide."
