The good news is there are ways to get a female DW Eevee now. One of the grottos has a very low chance for an Eevee, and the new Dream World area has Eevee in it.
You can only find Eevee in Grotto's if you participate in the Funfest Mission Japan is only getting.
Woops, forgot about that part. Still, there's Dream World now.
And I believe there's an Imposter Ditto available from grottos without this funfest mission event, even if it is only a 1% chance in one grotto, so all my dreams have come true. --- Pokemon White FC: 3568 3549 8596
