Wedding Dresses, Bridesmaid Dresses, Flower Girl, Gowns, Tuxedos, MN

I am helping pick the bridesmaid dresses for my friends’ wedding party. One of the girls will have a 4-5 month old at the time of the wedding, so of course her size at that time is unknown. Does anyone have any advice on how to chose an easily altered design?

I am planning to open a bridal consignment boutique and wold like to start out with a few gowns. I need help in finding wholesale suppliers of bridal, mother of bride and prom gowns, etc. Anyone have info on how to locate wholesalers?
