A BM of mine mentioned that a store near her carries the same line of dress I want to go with (we live 10 hours apart), and if she buys it there, the alterations are free. If my other BM's get their dress from one store, and she gets her's there, would that work? I've heard that sometimes the color can be off if they are not from the same dye. Not sure if that is accurate or not. Thanks!
