5 ways to turn your LBD into the perfect Halloween costume

We all have an LBD, our favorite black dress that we reach for whenever an occasion calls for dressing up. You can make it professional for the office, and add some accessories for a glamorous night out -- and now you can turn it into your Halloween costume.

The best part? These 5 ideas make for the perfect last-minute costumes because you can either borrow from the closet you already have, or borrow from the greatest closet ever -- also known as Rent the Runway. If your LBD isn't perfect for turning you into Audrey Hepburn or a '20s flapper girl, you can rent the look from Rent the Runway (last minute planning? They offer rush shipping!) and get dressed to the nines for much, much less.
