So I don't plan on doing any dress shopping until this spring/summer but I've been thinking about the BM's dresses... I originally wanted them long and formal but now that the wedding is in June, I'm debating if I should go short (it could potentially get pretty hot in STL!)... I know I want the material to be shiny to get the look I'm going for with the champagne color, but which material would be the most "breathable" if I decided to go long?
