I have a sticky issue with the dress code for my wedding. The men in my family have a habit of wearing jeans and a clean t-shirt to all the family events, including weddings, and I would like everyone to wear nice clothes, the kind you would wear to Sunday morning church. How do I tell everyone, on my website, that the dress code for the wedding is going to be nice slacks and a button down shirt, maybe even a tie? And without sounding "snooty"?
