This is the best idea yet for a fun prom, leave it to Sherri Hill to be the first. Start the evening with an elegant long gown and end it in a fun mini dress. All you have to do is untie the full taffeta over-skirt to reveal the most beautifully beaded and sequined cocktail dress you've ever seen. You'll wear this little beaded dress for years to come, but you'll never forget the night you wore it to your prom. Available in fuchsia, aqua, or white. You can complete the look with some hot Alisha Hill shoes.
