My fiance and I are having an adults-only wedding (with the exception of my niece who is the flower girl) and we are wondering if it would be appropriate to put the fact that it is adults-only on our wedding website. We are following all invitation etiquette and listing specifically who is invited on the invites, but you always have those few who don't get that. Would putting it on the website also be ok? And if so, where would you put it?
