I just reviewed your auction and #1, it's in violation of Ebay's policy by having a WEB link, you must remove that. #2 Your Title is lacking keywords: I would have something like:"Strapless Evening Gown-Scott Mclintock-NWT". The description would have all of the measurements and make sure you include the length.
