A Request

I've decided for numerous reasons that I'm going to wear flats for my wedding. I've been looking in stores and online for the past 8 months for simple, white ballet flats--but I can't seem to find any! Surely shoe designers recognize the enormity of the wedding market they are giving up. The only shoe I could find was this one, but while it seems to match my query I can't help but notice that it looks so stiff that it would just fall right off my foot (which could make the walk down the aisle a whole different ball game). Do you know what I mean? And I almost fell in love with this J. Crew shoe with the exception of its ivory color and its price tag!!! I mean seriously, $160 for a ballet flat??? Come on, J. Crew. So does anyone know of any simple, white ballet flats that don't have the absurd price tag? I would be extremely grateful if you'd let me know if you stumble across any.
