I had never heard of this tradition, but my futher MIL insists it is as common as "something old, something new ..."It's like everytime I see her she brings it up. The funny thing is she keeps telling me she DOESN'T want to wear blue. Like "I hope you don't mind! I know you're a very tradtional girl."And I just keep saying, it's fine really! I haven't even heard of this.Is it really as common as she says?
