A few weeks my SIL and I were chatting about the two dresses she had bought to wear to the family weddings (DH's cousin got married 2 weeks before us). She mentioned that the one she liked better (and planned to wear to our wedding) was floor-length royal blue and that she had silver sandals to go with it. I must have had a funny look on my face, because she asked if that was ok and I said it was find, but my BMs were wearing floor length royal blue dresses with silver shoes. She wore the other dress to our wedding and the blue dress to the cousin's wedding (and it looked very similar to the BM gowns). If she hadn't mentioned it, I wouldn't have cared, but it would have been noticeavle.
