So my mom is freaking out about what to wear for my wedding. She is very uncomfortable shopping in stores, so I'd like to find somewhere online that sells size - 30ish or 3-4x (she hardly ever buys clothes so doesn't know her size) dresses that would be appropriate for mother of the bride. It's a daytime wedding in May, so fairly casual. I'm at a loss because MOB isn't really my style and the places I can think of (Lane Bryant type) aren't hers. Help?
