So, this never occured to me until I started reading this board, but now I'm wondering...
I've added a FAQ section to my wedding website. One of the questions I added (because of course I've heard it a billion times) is "What should I wear?". We're not having a true black-tie wedding, but hope to keep it fairly formal, so have been directing people to dress up. Is this rude? I haven't added it to the invitations or any formal stationery, etc.
