So I've been doing a lot of thinking about my money situation and various aspects of the wedding... and I was wondering if it would be 1) tacky and/or 2) cost-efficient if I only used real flowers for my bouquet and my fiance's boutonniere, and used fake flowers for everything else (bridesmaids' bouquets, centerpieces, etc.)? Would I be better off going for all real or all fake? Any suggestions?
