This may be superficial (or even crazy), but I really don't want guests showing up underdressed for our wedding. I have a few family members who I don't think will really get the whole "semiformal" dress code. We are paying a lot of money for this wedding, and we don't want guests to misinterpret the dress code and show up in khaki pants and a polo shirt (or worse...jeans!) How can I make absolutely sure they know what to wear? Should I include the guidelines from the knot's cheat sheet on my wedding website or on my invitations:
"The invite says: "Semiformal" or "Dressy Casual"
Depending on the time of the event, you'll want to dress somewhere between formal and casual. Wear darker, more formal hues for an evening fete; opt for light colors and fabrics for a daytime wedding.He should wear: A suit and tie, dark or light depending on the season and time of day.She should wear: A cocktail dress or a dressy skirt and top."
And what if someone does show up in khakis and a polo shirt (or jeans)? Should I have security turn them away? Are there other options for this sort of dress code mishap?
P.S. - I understand that some people cannot afford to buy a whole new suit just for my wedding...but there are people who underdress just because they don't like to wear a suit or a skirt. So, please, no nasty remarks.
