Need A Wedding Gown

I have been looking for a wedding gown for quite a while. A lot of the dresses look very similar, but I would like to have something extraordinary. Does anyone know where I can find that? Also, I heard that once a year there is a sale for the floor sample designer wedding gowns? Does anyone know how to find information about that? I live in San Diego, but I can travel to Los Angeles or so. Or maybe someone had gown that I need. I am size 0-2 in regular clothes. Thank you so much.

P.S. I am looking for a white dress.
