I posted in the wedding gown thread that EVERYTHING Priscilla of Boston is on sale at all of their salons AND every salon that carries Priscilla (because the brand is being discontinued.)
Everything is on sale at like 50-60% off or more. Of course what's there varies because they're selling samples only, but it's worth checking out if you're looking for maids dresses or flower girl dresses (and you don't mind buying off the rack):
