My fiance and I have everything we need/want. Given that our wedding will cost a lot of money for our friends and family to make it since they're all out of state and it's an expensive time of year, we don't want guests to be burdened with having to buy a wedding gift or giving us money on top of that. Is it okay to just say no gifts necessary on the invitations? I just don't want some ignoring that and bringing a gift anyway, making others feel awkward if they didn't.
