I have my 20th high school reunion (!) in November. Which dress should I wear? It's going to be in a private room in a banquet hall. The invitation says "business attire." I feel like the one shoulder navy is probably too dressy, but I also think people are going to dress above business attire. And once I pick a dress, I have no idea what shoes to wear! I am hopelessly clueless when it comes to fashion, ha!
