Hello, I'm struggling with etiquette on my shower. My MOH suggested having a more casual coed shower, backyard grilling style, which my fianc and I really like. But when I went to make our guest list, I'm at about twice her goal of 20 people with just the obligatory invites immediate families, bridal parties and sig others. I know that this is a financial investment on her part, and I don't want to strain that. But I'm also nervous about slighting somebody that will feel hurt if they aren't invited. How should I approach this?
