I had this same issue. After you wash it a few times it definately lightens up a bit. Mine was still a touch too dark, but not way too much. I had different issues and didn't end up wearing that piece and ordered a lighter color, but had it just been because of color I would have darkened my own hair just SLIGHTLY darker and it would have matched (no one would have even noticed I darkened my hair). So first wash it a few times and let the factory residue clean off it, then let it dry and see if it matches then. If still slightly dark, just ask whoever will do the cut in if it will be possible to color either the piece or your own hair to match. But wash it first, i was surprised by how much it lightened (though still not quite enough in my case, but enough it didn't worry me).
