I am loving the dress-with the orange sash-beautiful. I already purchased a dress and didn't have a train on it-darn it. What are your prices for these items? That may help too.
Isn't the wedding shower gift the gift? Doesn't that mean you already gave them a gift? I am trying to figure out the dilemma. As for the etiquette-they should have sent you a real invite-not a fb message-in my opinion.
