If you decide to reduce the price of your dress, just locate the dress on your "My Listings" page and click "Edit Listing".
Scroll down until you come to the asking price fields. Simply enter the new price and hit update.
Your listing will be marked with a reduced tag in the search results and also shown at the top of the reduced dresses section of the site.
Note: You will not be able to raise your asking price above its original value.
