I definitely like the idea of them but I have never been to a wedding that had one so I can't tell if they are a waste of money or if guests really like them. Is anyone having or did anyone have one at their wedding? If so, did they get worn by guests? Where are you getting them [I've looked at Old Navy but so far they don't have our colors [orange/yellow/mint green]]? Do you just get a mix of sizes and hope that they fit everyone?
