I am throwing a bridal shower, and the bride and groom aren't going to register for anything. So, I am making the shower a romance themed shower, and would like to suggest to people that they bring "romantic" gifts. I also want to make sure the guests know they aren't expected to bring anything racy - lots of things are romantic, like a picnic basket for two, something the couple can do on a "date night", etc.
Any suggestions on how to word this either on the invitation or on a slip of paper included with the invitation?
