I bought it at David's Bridal in November 2013. I normally wear a 12, so it's actually true to size. It's only been worn for about 6 hours total. Before that and after, it's been kept in the original garment bag. With alternations (plain sash instead of the beaded one it came with and putting in a bustle) it ended up costing about $800.
Included with dress: additional beaded sash & original garment bag.
