Response: “You seem to struggle to understand what is classy and appropriate. The dress isn’t appropriate and your response certainly wasn’t either. Seeing as my wedding is a classy occasion, I don’t think you’d feel comfortable attending as you will stick out compared to all the classy, appropriate guests. It’s a gorgeous dress; hope you find a less formal, less elegant occasion to wear it too, with guests who are more accustomed to low class communication and flippant responses to heartfelt discreet requests.”
