I just typed in "wedding dress no reserve" on Ebay, a few times a week until the strapless dress appeared. It's Nicole Miller, and I have a dress by her so I knew it would fit. So I bid on it. The same day I placed the bid on the Nicole Miller dress, I was visiting a friend. I commented on some of her wedding pictures, and she whipped out her dress. And convinced me to try it on (it's a Jim Hjelm), then refused to let me leave without it. By the end of the day I had two great dresses.
It was a total fluke. If anyone wants the strapless one, pm me and you can have it after my wedding in May. I plan on using for a TTD, so it may not be so perfect. It's a 6.
