How many dresses did you try before you found THE ONE?

I've been dress shopping this past week, and I've tried on 50+ dresses to no avail. The few I have liked, there's always been just ONE THING wrong. (My brother said one reminded him of a lace tablecloth. That was an immediate no-go. Hah. Sigh.) I'm just starting to wonder if my dress is even out there. Did anyone else have a similar experience? Did you eventually find the dress or did you have something made? I feel like I'm running on fumes here. Side note: I know I have plenty of time, but I'm going back to school to finish my degree in the fall, so I'm trying to get as much done before school takes over my life.
