vintage Victoria style garments for prom

I know this might be a long shot, but I remember reading something about a store in Morton that had been given bridal dresses/prom dresses for sale. I am in need of a reasonable priced prom dress for a size 0 or 00 for my 17 year old daughter who wasn't blessed in chest area. My daughter is only 5 foot and very petite. If anyone knows where we may find one please let me know. vintage Victoria style garments for prom
