Thanks for the answer Kasumilove: the hair doesn't appear at all in the DLC costume, or better doesn't appear at all the option to select another hairstylke: Honoka hair' selection is disabled how it should be for standard in the game.
And yes, I followed the giude and added it on the costumes appearing "black text" in Ink reshuffle.

Great work so far! If only it was possible for you to swap the effect of sakura petals during the teleport of Kasumi while using that outfit with Nyotengu's carrot (from her sexy bunny costume) as it happened in the original DoA1, this would be even more awesome
