Pretty good.
This is what a defiantly what a Non-Adult Dress up game should be like. Organized clothing/hair/etc, Everything just clips on, and a good selection of colors for everything.
Music and scenery are my main issues.
While the music is great, it's only has one song and that can get boring fast when you want to flip around and play with different sort of outfit combinations.
Scenery.. you only have three scenes. None of them were bad but it just didn't go well with the idea of a vampire hunter (The graveyard scene didn't cut it for me.) I think you should add more scenes and rethink on the ones you do have.
