grandmother of the bride dresses

I need advice or guidence with my wedding. I only have two of the million things planned. I really need to kick it into high gear since I have 9 months. I haven't completely settled on the location due to more then half the people who were invited said they can't travel to seldovia. Where and what is the best place for bridemaid dresses in a decent price range(reniassance feel), best place for a suit/tux, anything else for a calm, rustic(garden/reniassance themed) wedding. grandmother of the bride dresses

Ps. Scared getting dresses from online hate getting attatched to a look and its not in all sizes needed.
