Turns out I was a picky bride, this was the third wedding dress I got! Third time's the charm, I suppose. It was purchased with my mom and sister at The Sample Rack in Philadelphia, a great little shop that sells samples for $1300 or less (so I didn't need to pay full retail price but I looked it up for the sake of full information here).
I got married in Washington DC in October 2013, I happily wore the dress for the entire wedding day, including to the reception.
