Looking For A Pantsuit To Wear On My Day

I never wore dresses or skirts very much and I want to get a very classy and feminin pantsuit to wear to my wedding. I can`t seem to find a plain white(only white, no other color at all) pants suit anywhere. Does anyone know where might be a good place to look? I have checked Dept stores around me as well as thrift stores(i really want something brand new, crisp and clean looking though)...with no luck. Bridal stores do not have white pant suits either. Any suggestions?
